>> then a contentious spike lee on "chi-raq" and chicago. >> i didn't get off the turnip truck. >> let me finish. >> and as the leaders of the free world race to try and save the planet in paris, ted cruz held his own climate summit in d.c. today into this is a hearing on the science behind claims of global warming. > "all in" starts now. good evening from new york. i'm chris hayes. donald trump is now putting the republican party on notice. that if they don't treat hip better, he may run as an independent. today he reiterated support for his widely condemned proposal to ban all muslims coming into the u.s. >> what it is is common sense. now, remember this. until our country's representatives can figure out what is going on, we're not talking about the japanese internment camps. not at all. but we have to get our hand around a very serious problem. it's getting worse. >> do you regret urban on muslims which some people think is un-american? >> not at all. we have to do the right thing. somebody in this country has to say what's right. it's short-term. let our country get its act together. >> earlier today, trump tweeted a new poll indicates 68% of my supporters would vote for me if i ran as an independent based and a new poll from "usa today." that wouldn't be enough to win a general election but the threat he began making at the beginning of his campaign and sort of put to rest when he signed the rnc pledge to support the eventual republican nominee and not run as an independent candidate. he held a press conference specifically to show off that signed piece of paper and that the event in early september, i asked him why we should believe he'll stand by the pledge. >> you bragged in the past about how when it suits you, you used bankruptcy laws. you joked to the audience independence alabama about taking the money and screwing them afterwards. why would anyone think this means anything? >> this is a self-funded campaign. we have our heart and soul in it. i don't need money. this is going to be a campaign like i think no other. >> in other words, he did not answer the question. and since then, he's made noises about the importance of being treated fairly. today in the wake of gentle to strong criticism of had his call to ban all muslims coming to the u.s., trump reprised his they're the with that tweet. it may have been triggered by reince priebus who after remaining silent yesterday today told the washington examiner about trump's policy, i don't agree. we need to take on islamic terrorism but not at the expense of our american values. when asked about the implications of trump's plan on the future of the gop, reince said that's as far as i'm going to go. just moments ago, presidential candidate hillary clinton slammed trump's proposal. >> this is both a shameless and a dangerous idea. at a time when america should be doing everything we can to lead the fight to defeat isis and other radical jihadists, donald trump is playing right into their hands. and some of his republican candidates are saying that his latest comments have gone too far. but the truth is, many of them have also said extreme things. they are all driving the exact narrative that have jihadists want to advance. >> today, republican leaders in both the house and senate distanced themselves from trump's position. >> with regard to the remarks by one of the presidential candidates about restricting muslim travel to the united states, let me just first say that would be completely inconsistent with american values. >> this is not conservatism. what was proposed yesterday is not what this party stands for. and more importantly, it's not what the this country stands for. >> other republicans speaking out against the trump proposal include senator john mccain, former senator bob dole, john boehner, former vice president dick cheney and mitt romney. here's the important point. they have stopped short of saying they would not support trump if he were the nominee. sometimes by insisting he will not be the nominee. some republican presidential candidates notably bush and kasich have criticized trump vociferously and others like ted cruz simply said they don't agree with him. >> i disagree with that proposal. i like donald trump. a lot of our friends have encouraged my to criticize and attack donald trump. i'm not interested in doing so. but i believe we need a plan that is focused on the direct threat and the threat we're facing is radical islamic terrorism. >> bear in mind that cruz was holding a press conference on his proposed bill the terrorist refugee infiltration act which is notable. while many republicans are trying to distance themselves from trump and his proposal, his call to ban muslims entering this country is combining two gop policies for syrian refugees and applying them more broadly. senator ted cruz, jeb bush and mike huckabee all favored some sort of religious test for refugee entrance in the wake of the paris attacks. the republican-led house voted last month to pause emitting it syrian and iraqi refugees. trump has taken the religious test and temporary ban and applied it more broadly to anyone seeking to enter the country. now everyone is wondering what will the next step be on his road to what we're calling here -- joining me now former governor and dnc chair howard dean. msnbc political analyst. well, howard, where to start with this. >> another unbelievable day on the campaign trail. >> yeah, i mean. >> unbelievable. >> deeply disturbing. let's start with the reince priebus. you headed up the dnc for a while. there's some level which the head of the party has to remain neutral while a campaign is going on, while a primary is going on. at the same time, you have a candidate floating an idea that's so obviously odious. so sort of toxic that you think they would be stronger. what do you think of reince priebus' statement? >> i think he probably did what he had to do. you're right. i would never have said anything like that. i don't have candidates like trump and cruz to have to worry about. so you know, his problem is he fears for the future of the republican party as he should. so rule number one is, you've got to the stay completely neutral. rule number two is save your party when you're the chairman. i think that's what he chose to do. the two rules conflicted with each other and he did what he had to do. i think that was the right thing to do. >> there's two ways i think of viewing what's happening here. one is that donald trump is tapping into some part of the republican base that is sort of caught up in this nationalist xenophobic fear and suspicion. and you know, he's being condemned by other people in the republican party. the other wave looking at it is, the republican party has laid the groundwork in many ways. >> that's right. >> in the mainstream for what donald trump is proposing. how do you see it? >> i see it as the second. i think this goes all the way back to the southern strategy of richard nixon who made it a deliberate strategy to pull the southern democrats who were racist out of the democratic party into the republican party. and that will really -- that swing group then became republican and that kind of thing has been going on for a long time, even ronald reagan who many people really like used 0 to dog whistle stuff about welfare people driving around in cadillacs. i don't think people were white that he was talking about. i mean, there's a lot of that kind of stuff that has been going on ever since 196 and now it's coming home to roost. this is the election where the republicans have to decide whether they want to appeal to young people who aren't going to put up with any of this stuff no matter how conservative they are economically or whether had he want to ride this pony off into the dust. that's where they're headed right now. >> there's also a debate whether trump is tapping into something specific to this moment in american politics. there's some conservatives attempting to blame barack obama for donald trump's rise. or whether he's just taking advantage of this new landscape both in terms of money and funding and media and the decline of the party's strong institutions to sort of channel a voting bloc that's been there a very long time. >> trump is a master showman. he really is. i don't think he would have gone this way unless he knew what he was doing. one of the things i have counted him out at least eight times since this all started last march or whenever it was. the guy knows what he's doing. the only problem is what he's doing is a not good for the country and probably not a good strategy to win a general election. he could win the republican nomination. >> you really think that? >> i do. i think donald trump right now, he wouldn't get to 50% of the odds because there's so many candidates but he has the best odds of winning the republican nomination of any candidate out there. that doesn't mean he will. but i think he's got a good shot. >> we should note that there are a lot of people speculating part of his announcement yesterday had to do with a in you poll showing him behind in iowa to ted cruz. although polling out today showing him with a pretty commanding lead in new hampshire. howard dean, thank you very much. >> thank you. joining me now john cassidy staff writer for the new yorker who wrote a piece donald trump's is now america's maureen le pen. national front in france just enjoyed a huge victory in the elections there. what do you mean by making this parallel? >> france has long had a national front people which appeals to the disaffected white guy and runs as a separate party. on sunday, they actually won enough seats in regional elections to end up running six major departments in france. so they're actually going to be running a lot of local governments. the message they've been running on is very similar to what trump's been running on, close the borders, marin la pen says no more immigration, no legal and illegal immigration. number one close our borders and shut down islamic mosques, have a crackdown on suspected muslims. generally take a very authoritarian approach similar to what donald trump's been talking about here. >> and one of the things we're seeing here that i think is worrisome is the migration of things that were fringe towards the center. so "the new york times" yesterday i think in writing up trump's proposal had a great clause that said an idea normally associated with hate groups which is a diplomatic way of saying that this is sort of fundamentally odious. and we've seen that. are you watching that happen here in american politics? >> trump has a genius for pushing the envelope. it's working for him. and trump is basically a gambler. he'll stick with it when this strategy as long as he thinks it's winning. first he says let's deport 11 million undocumented -- >> his first day he says they're all rapists and criminals. >> completely impractical policy. everybody says he's crazy. it takes him to the top of the polls. last month or so, it looked like he was dipping a bit and then the french terrorist attack starts. as you mentioned, ted cruz was challenging him in iowa. it wasn't -- ben carson was doing well. if you're trump, you're thinking i need to do something to reassert my lead. bang, france bo blows up. he says let's have a registry of muslims. president obama is not protecting the country. let's crack down on the muslims. that works. all the other candidates support that and he's not differentiating himself. >> the registry of muslims. >> he backed off a bit and said a database. >> a lot of people said -- we shouldn't say all candidates agree with him. >> they agree with the database of suspected radicals. the fact is they went some way in his direction. he had an incentive to go further and comes up with this idea of banning travel to all muslims. we'll have to see if it works in the polls. there's no immediate indication it's going to damage him. >> part of the problem is the logic that's been created and the rhetoric joined by many people in the media and politics in the wake of paris or san bernardino, makes this not as insane or offensive as it might have been. because if you keep look at these people. next question becomes syed farook was an american citizen. so what are you going to do about that? right? you can imagine he's already in favor of rounding up and deporting 11 million other folks. i mean who knows. >> two things need to be said. number one, there's a legitimate worry which lots of people have got they're going to be some crazy guys going around shooting americans in shopping malls. theaters. that's perfectly legitimate. it's perfectly legitimate for people who say what's the government going to do about it. trump takes that legitimate concern and twists it in a very particular direction where he knows the rest of the party can't really follow him because this is such a clear violation of american values, maybe a violation of the religious freedoms under the constitution. he's talking about american servicemen not being able to re-enter the country because of their religion. it's crazy. you think it's crazy. but actually it may be politically quite smart because there is a rebel of concern out there that sort of goes to the trump's central strength which people don't think of him as a regular politician. he'll say anything and do anything. one lesson is howard dean said this, people have been looking for the breaking point forever from almost the first day. there is no breaking point. i don't think this will be a breaking point. some percentage of people want this. he's giving it to them, a. b, whether it's politically smart or not, there are real genuine consequences both around the world and here. we're going to be talking about some of that when people start talking like this. yuan cassidy, a great pleasure, thank you. coming up, the industry of islamaphobia and debunking the poll that will donald trump touts at the reason to keep muslims out of in irk. plus a former george w. bush official who has been accused of being a secret muslim radical will join me. and later spike lee gets candid about his latest film "chi-raq." my interview ahead. >> part of the objection to that term -- mom. the twins. aunt alice... you didn't tell me aunt alice was coming. of course. don't forget grandpa. can the test drive be over now? maybe just head back to the dealership? don't you want to meet my family? yep, totally. it's practically yours, but we still need your signature. the volkswagen sign then drive event. zero due at signing, zero down, zero deposit, and zero first months payment on a new jetta and other select models. if a cold keeps you the up at nightis... you can't just catch up on sleep the next day. new alka-seltzer plus night cold & cough liquid relieves tough cold symptoms and quiets coughs for up to 8 hours... ...to help you sleep at night. new alka-seltzer plus night liquid. great change comes from doing the right thing. like the radical idea that health isn't an industry. it's a cause. so we do things differently. we combine care and coverage. and believe prevention is the most powerful of cures. so forgive us for not going with the flow. we just think the flow should go with us. which makes us rebels with one cause. your health. he's taken a page from the playbook of hitler. donald trump is literally trying to radicalize our fellow americans against our american muslim and international muslim brothers and sisters. >> he feels that we are at war. >> he's an [ bleep ] hole. i mean, i apologize, reverends. >> that was philadelphia mayor michael nutter with a response to donald trump's proposal to ban muslim visitors to the country and immigrants. the press conference was held alongside the leaders of the philly religious community after, this is important, a bloody pig's head was found thrown at a local mosque overnight, an incident that was captured on surveillance tape. also it's not the only potential hate crime reported today. a somali restaurant in south dakota was set on fire where nazi graffiti had been painted on the exterior. we'll take a deeper look at islamic xenophobia next. this is the one place we're not afraid to fail. some of these experiments may not work. but a few might shape the future. like turning algae into biofuel... ...new technology for capturing co2 emissions... ...and cars twice as efficient as the average car today. ideas exxonmobil scientists are working on to make energy go further... ...no matter how many tries it takes. energy lives here. this was from the center for security policy, very highly respected group of people who i know actually. this is people living in this country. 25% of those polls agreed violence against americans is justified. as muslims. 25%. >> unveiling his plan to keep muslims out of country last night, donald trump cited polling that claims to show large members of muslim americans support jihad against the west which is terrifying if true but of course, it's a terrible poll. as georgetown's university points out it was a nonprobability based on this survey conducted online by a conservative polling firm which means the results don't really mean anything in any scientific sense. there's the matter of the group that commissioned the poll. the center for security policy which trump up calls highly respected is run by a man named frank gaffney, a former reagan official who is called one of the nation's most notorious islamaphobes. he's advancing the campaign against the so-called ground zero mosque in new york spreading the theory the american muslims are plotting to replace the constitution with sharia law and accuse the obama administration as being a front for the muslim brotherhood and calling for mccarthy style hearings to root out the infiltrators. among the specific individuals he's charged hillary clinton's aide huma abedin, supreme court justice elena kagan and perhaps most head scratchingly anti-tax crusader grover norquist. gaffney wrote a whole book accusing other republicans of forming an islamist front group. that was enough to get him barred from cpac, the annual conservative gathering. the center for security policy stood by the poll findings trump cited and said the southern policy law center by slanderously americans who raise warnings about islam is aiding jihad's perpetrator is by suppressing speech that is critical to them. >> this is not a fringe figure. some of the presidential candidates participated in a forum he already hosted over the summer in new hampshire. he's holding another one in las vegas on monday on the eve of the next republican debate. we will be waiting to see just who attends. joining me now, a former official in the second bush administration who has been accused by frank gaffney of having ties to the muslim brotherhood. those are spurious allegations to be clear. suhail, i want to hear from you the connection between the groundwork that's been laid by individuals by frank gaffney and what trump did yesterday. >> hanks for having me on. absolutely, frank gaffney for over a decade has been insidiously smearing the good name of americans in public service, folks as you pointed out on both the republican and democratic side of the aisle just because of their faith and because of these efforts, he's been marginalized by members of congress, by senators, by various groups particularly conservative groups who has paul ryan has rightly pointed out about trump's comments that there is no place for such bigotry within the conservative movement. unfortunately, unfortunately, he has been able to take his bigotry to presidential candidates like dr. carson and now donald trump and has pushed this bigotry out into the mainstream of the campaign. unfortunately these candidates have taken his bigotry and this bogus data and pushed it out there. if bigotry is a disease, frank gaffney is the patient zero and he's really the bob you'll of politics if i can mix my metaphors. his hatred has become mainstream with some in the presidential field. i'm confident the vast majority of all americans will reject this bigotry very soon when it comes time to vote. >> you quoted paul ryan who gave a fairly impassioned and definitive thorough speech about trump's proposal. there's no place for bigotry in conservatism. that strikes me as an aspirational statement rather than a descriptive one. donald trump is running in a republican primary getting 25, 30%. there is a market for this. frank gaffney didn't just appear out you have nowhere. there is some portion of the republican base and it's backed up by lots of polling. you've got, you know, lots of american republicans telling pollsters they think islam is incompatible with american democracy, a slim plurality in certain states saying it should be illegal. >> first donald trump, dr. carson, they've been successful so far in this primary season largely because they're outsiders, they're taking rang of very anti-washington establishment sentiment out there. that feeling obviously is real. we just saw the change in the speaker in the house due to a significant segment of house members feeling they wanted a change in leadership. but i would argue that people like frank gaffney are taking advantage of that popularity, taking advantage of that anti-washington establishment sentiment out there and latching on with this anti-muslim and anti-immigrant type of hysteria. unfortunately, i'm not letting dr. carson or mr. trump off the hook. they are completely responsible for putting this hate out there. but we need to be aware, as you rightly pointed out in the beginning of the segment there is a genesis for this and that is hate groups like mr. gaffney's that are pushing this out and getting candidates to adopt this and pushing them out into traffic on this type of bigotry. >> part of the issue is this sort of suspicion that has waxed and waned how it blankets muslim americans. when someone accuses you suhail khan that you have the name you have and the faith tradition you have and you must be some cryptoplant of jihadis, what does that feel like? >> when he first started coming after me and my family, i can't lie. there was a sting to that hatred and that bigotry particularly because it wasn't true. but having a good circle of friends and support both from my family and my friends here in washington, d.c., i've come to brush off those accusations. it hasn't hurt me professionally or personally. what does hurt meet is when innocent people in public service are the next targets. that's why i've always felt that it's important for me to stand up in defense of those and in defense of innocent people. if you're a young american thinking about getting into public service and you see that there are these bigots out there targeting you, trying to demean you and your family, traditions, just because as loyal as american you may be because you might follow traditions that might be a little different, that i think is most reprehensible and why i feel it's important to stand up to that bigotry because in fact we are americans and we are under attack here. there are vicious violent terrorists who want to do us harm. we saw that in san bernardino. we need to stand together against this bigotry and only give in to the terrorist biz dividing ourselves based on religion, but instead we should join together as americans regardless of our ethnic and religious background to fight this enemy and defeat them. >> thank you. >> thank you, chris. >> still to come, my interview with spike leon his new controversial movie "chi-raq." what he said happened in his meeting with chicago mayor ram emmanuel. >> he was trying to convince me to change the title "chi-raq." first of all, i didn't come up with the title. local chicago rappers came up with the title. his reasons for changing the title were troubling to me. i'll be programming at ge. oh i got a job too, at zazzies. (friends gasp) the app where you put fruit hats on animals? i love that! guys, i'll be writing code that helps machines communicate. (interrupting) i just zazzied you. (phone vibrates) look at it!

[ speaking foreign language ] this morning he was under attack on his own side of the atlantic for suggesting muslims should be banned from coming to the u.s. [ speaking foreign language ] >> republican front-runners plan to bar muslims from entering the u.s. has been almost as big a news story around the world as here. trump has at least one international supporter, gert wilders the head of the far right dutch freedom party who tweeted i hope donald trump will be the next u.s. president. good for america, good for europe. we need brave leaders. for the most part reaction around the world has been overwhelmingly negative. representatives of the french and british governments condemned the proposal. egypt said it amounted to hate rhetoric. londoners were incensed at trump's comments about no go zones in their city. >> we have places in london and other places so radicalized that the police are afraid for their own lives. we have to be very smart and very vigilant. >> london mayor released a statement crime has been falling steadily in london and new york. the only reason i wouldn't go to new york is the real risk of meeting donald trump. even the london police weighted in, we would not normally dignify such comments with a response. however, we think it's important to state to londoners that he could not be more wrong. any candidate for the presidential election in the united states of america is welcome to receive a briefing from the met police on the reality of policing london. then there was this from fellow brit, j.k. rowling. how you horrible. voldemort was nowhere near as bad. i use what's already inside me to reach my goals. so i liked when my doctor told me i may reach my blood sugar and a1c goals by activating what's within me. with once-weekly trulicity. trulicity is not insulin. it helps activate my body to do what it's supposed to do release its own insulin. trulicity responds when my blood sugar rises. i take it once a week, and it works 24/7. it comes in an easy-to-use pen and i may even lose a little weight. trulicity is a once-weekly injectable prescription medicine to improve blood sugar in adults with type 2 diabetes. it should be used along with diet and exercise. trulicity is not recommended as the first medicine to treat diabetes and should not be used by people with severe stomach or intestinal problems, or people with type i diabetes or diabetic ketoacidosis. trulicity is not insulin and has not been studied with long-acting insulin. do not take trulicity if you or anyone in your family has had medullary thyroid cancer or multiple endocrine neoplasia syndrome type 2 or if you are allergic to trulicity or its ingredients. stop using trulicity and call your doctor right away if you have symptoms of an allergic reaction, such as itching, rash, or difficulty breathing; if you have signs of pancreatitis such as severe stomach pain that will not go away and may move to your back, with or without vomiting; or if you have symptoms of thyroid cancer, which may include a lump or swelling in your neck, hoarseness, trouble swallowing, or shortness of breath. medicines like trulicity may cause stomach problems, which could be severe. tell your doctor about all your medical conditions and any medicines you take. taking trulicity with a sulfonylurea or insulin may increase your risk for low blood sugar. common side effects include nausea, diarrhea, vomiting, decreased appetite, and indigestion. some side effects can lead to dehydration, which may cause kidney failure. with trulicity, i click to activate what's within me. if you want help improving your a1c and blood sugar numbers with a non-insulin option, ask your doctor about once-weekly trulicity. and click to activate your within. you can't breathed. through your nose. suddenly, you're a mouthbreather. a mouthbreather! how can anyone sleep like that? well, just put on a breathe right strip and pow! it instantly opens your nose up to 38% more than cold medicine alone. so you can breathe and sleep. shut your mouth and say goodnight mouthbreathers. breathe right >> dude, this is about life and death, about a community that's a wreck. and you want to sit here and talk about how women behave? fool, we try too long free these slaves, slaves to the madness, slaves to this violence and what you just want us to silence? we're going to make sure these fools put down these guns. and stop thinking that this craziness is fun. >> spike lee's new movie is called "chi-raq"". it is a fantastical mythical modern adaption of lysistrata. where women band together for a sex strike to put an end to the gang violence in their chicago neighborhoods. film has been controversial from the start from the title which conjures up the images of a distant war zone to the premise criticized as an front to residents of chicago where gun violence is a deeply serious reality. i sat down with spike lee to talk about the movie, including a series of tweets from chance the rapper who is father is ram emmanuel's chief staff and the director of the mayor's office of public engagement. i asked spike if this movie is really about the city of chicago into this is about america because a big take away for me for the film is guns. and it's a question that we've, i don't know if we're afraid to deal with it or don't want to deal with it. i don't know what it is, but i think that it is insane. it's complete insanity that 88 americans die every day due to gun violence in this supposed civilized country that we live in. >> i mean part of what i think the some of the criticism of the film has received particularly from folks in chicago, let's just stipulate if you make a movie, if you're from a place people are going to be why did you make a movie about this place. >> also if you're me. >> there's a certain amount that comes with the territory. >> i understand that. >> when i watched the movie i thought to myself, this is -- it's a myth. it's a myth. it is a mythological film as much as it is a realistic depiction of actual urban violence. >> i use the term heightened reality. just the fact that we took this play written by the great greek playwright aristophanes. he wrote in 4 b.c. and moved to southside of chicago where the premise is women take control by withholding sex. i mean, it's heightened reality. >> what do you mean by that? >> is that people are not going to start breaking into song and dance singing and people aren't going to walk around today speaking in verse and rhyme. so this is a heightened reality. >> chance the rapper who is from chicago and as he was coming up before he became big was rapping a lot about this issue about violence in chicago, went off. he said the idea that women abstaining from sex would stop murder. a slop in the face to any mother who lost a child. you don't live here. you've never watched someone die here. don't tell me to be calm. >> first chance rap will say full disclosure. his father works for the mayor. he's the chief of staff whatever the title is. his father is the chief of staff. show me any criticism, if he's so concerned about chicago, do your research. show me where he's made a criticism about the mayor. i think your findings will be surprising. he has not criticized the mayor. why? his father works for the mayor. and on top of that, jennifer hudson is in the film. she plays a pivotal role. her mother, brother, and nephew were murdered in chicago. why would she be part of a film if -- if what chance rapper is saying is true why would she be in the film? >>age you just mentioned the mayor. the mayor is under tremendous -- >> the feds are in town. the feds are in the city of broad shoulders. >> now. >> the feds. f-e-d-s. >> you met with the mayor before you started filming. > we met in preproduction. >> what was that meeting like? >> it wasn't good. >> he was not happy. >> he was not happy. he never said spike, you can't make this film. he couldn't do that. he said he liked my films in the past. but he also said that he wish -- he was trying to convince me to change the title of "chi-raq"". first of all, i didn't come up with the title. local chicago rap areas came up with the title. his reasons for changing the title were troubling to me. he said the title "chi-raq"" would hurt tourism and economic development. >> but understand why you know, and i recognize that "chi-raq" spike lee "chi-raq." it comes from folks in chicago. you recognize that term, part of the objection to that term is sometimes when we talk about urban violence and i'm talking about us, me, the media, okay? >> all right. >> you can talk about west side of chicago, detroit, a lot of places. it's very easy in communicating how bad it is and how traumatic it is to live there to make it seem like some other place. that's not us. that's "chi-raq." that's some other place. >> i totally disagree with that. if you saw the film angela bassett, you might have forgotten, angela bassett has a scene where she says is, people don't know what they're talking about. a character in the movie says she hates the word "chi-raq." >> you have characters ins the movie saying everything. >> people have to have a right. they want to see the different viewpoints. as a filmmaker, i'm not going to have every character in my movie say what i believe. >> right, now. >> that's what he artists do. >> so the other reason i think -- this has true before people saw the film. like my impressions going in and what the film were were not the same is that in the wake of the last two years of black lives matter protests, one of the things we hear all the time is black on black crime. you guys are protesting because you know, a cop shot this young black man but young black men kill young black men all the time. there's a sense in which people feel like that is a disingenuous misdirection. >> people look at my body of my work. i made ma'am malcolm x, do the right thing. look at the board certified work. i didn't get off the turnip truck. let me finish. >> right, right. >> sir, it doesn't matter to me what color or complexion that pulls the trigger. as an artist, i'm going to look at both sides. there's a specific scene where samuel jackson talks about it. there's a gang banger on one side and chicago cop on other. if you're a parent -- whether your child got killed by a gang banger or cop, you still feel the same. >> right. >> your child is dead and your child is never coming back to you forever and for the rest of your life, you are going to have a hole in your owl. oh it doesn't matter. i'm going -- it doesn't matter to me. as a cowriter, director, producer of this film, it doesn't matter. we dealt with both in this film. >> spike lee's "chi-raq" is now playing in theaters nationwide. i can honestly say it is unlike anything i've seen in a very long time possibly ever. still ahead, as world leaders work against the clock at the climate change summit in paris, these unbelievable images out of china where the levels of air pollution have triggered a red alert in the capital city. all that's coming up. when you've got a house full of guests on the way and a cold ws pressure, you need fast relief. alka-seltzer plus severe sinus congestion and cough liquid gels rush relief to your tough symptoms. to put you back in control. [doorbell] woman: coming! alka-seltzer plus sinus. at ally bank no branches equals great rates. it's a fact. kind of like shopping hungry equals overshopping. as world leader race to avert full on climate crisis, republican lawmakers in america exercise full-on denial. that's next. ♪ ♪ today, right now, nearly 150 world leaders are gathered in paris racing to get a deal on global carbon emissions that could save the planet from climate catastrophe. back in washington, texas senator ted cruz hoping to join the ranks of those world leaders just wrapped up a senate subcommittee titled data or dag ma. >> i believe that public policy should follow the actual science and the actual data and evidence and not political and partisan claims that run contrary to the science and data and evidence. >> gop presidential hopeful follows in the footsteps of his fellow republicans in the house who have used the platform of the science committee to spread junk science and misinformation. democratic senators slammed the hearing and senator markey dubbed cruz a sub cult of deniers. the witness list of the hearing bears that out. there were three scientists notable climate deniers plus a right wing author with no scientific credentials and one lone scientist who affirms the consensus that the planet is warming in part due to human activity. if we don't do anything to change the status quo, we'll be faced with the catastrophic consequences of our action. that lone scientists was invited to testify on the committee. senator gary peters ranking democrat on spice science and competitiveness. senator, what was this hearing about today? there were not that many people there. this seemed to me like essentially a ted cruz campaign event held in the capitol. >> well, i think that's pretty accurate description. you had some folks testifying who were basically denying that climate change is caused by humans and is a significant threat. it's a debate that seems to continue to go on in the halls of congress but as you mentioned in opening the segment, it's not happening in the world community. that's why we've got nearly 190 countries coming together in paris. we have 97% of the scientists climate scientists in this country who believe that climate change is real and not only is it real, humans have a significant play in it and we have deal with it. we also have the major companies in this country that have all come out to deal with it. to have senator cruz put this show together is really disappointing particularly to use the science committee. we should be talking about how do we deal with this issue? we know we have potentially catastrophic impact as a result of climate change. we should look at how do we further study this so we can put together the kind of public policy that can mitigate this. we can deal with it but have to put our best minds to trying to solve it as opposed to trying to deny its existence. >> do hearings like this one and there have been many hearings in the house committee that have drawn a lot of criticism for essentially being used to harass scientists, do hearings like this one do tangible harm or are they just a sideshow? >> it's somewhat of a sideshow in the fact we've got to keep moving forward. got to be able to put ideas forward. in dealing with climate change, as well, this is an opportunity for us to be looking at economic development, as well. in my state of michigan, solar, wind, economic drivers. this is about what's doing good for the economy. creating a sustainable economy while addressing the climate change issue. for whatever reason, senator cruz believes this good politics for him. i'm sure it is with parts of his republican base. but it is bad public policy and for someone who aspires to be the president to think you would be making public policy when 97% of the scientific community says that what you're trying to do is wrong to me really is a testament to his lack of ability to provide the leadership necessary for this country. >> is denial disqualifying to be president of the united states in your mind? >> i think it is. if you are not willing to work with the vast majority of the scientific community to figure out how to deal with this issue, this is a national security issue. our witness was a former admiral in the navy in charge of meteorological services for the u.s. neighbor. he made the comparison which i thought was very important. if you're a military commander, making decisions and you're using intelligence to help determine whether or not your operation goes forward, if you had 97% certainty, you would definitely act. in fact, it would be malpractice not to act. you could lose your whole army if you don't act when you have 97% certainty. this is something that we need to deal with and to have someone who wants to be a commander in chief but doesn't understand how important it is and how much evidence is behind i think is very telling. > thanks for joining me. appreciate it. we will go live to paris to see how the negotiations are going on there be next. this is the one place we're not afraid to fail. some of these experiments may not work. but a few might shape the future. like turning algae into biofuel... ...new technology for capturing co2 emissions... ...and cars twice as efficient as the average car today. ideas exxonmobil scientists are working on to make energy go further... ...no matter how many tries it takes. energy lives here. by day, they must stay warm. challenges to the feet. but by night, beautiful, smoother and ready to impress the other party animals. dr. scholl's dreamwalk express pedi when a moment spontaneously turns romantic, why pause to take a pill?
