Support of the African American senator, tim scott. Help me welcome marco rubio. Reporter like a prize fighter entering a ring, marco rubio took shot at president obama. With a well worn line. Were going to undo the damage that barack obama has done to this country. [applause] now, when i say this, and i say that more than once, then the press says hes repeating himself. Trying to undue the disaster he made at the New Hampshire debate, saying a phrase four times. He seems to have roiferred and threcovered andthe endorsement. Haley healy. I hope hes going to win the state with a tail wind. Recent policies suggests bush remains near the bottom of the republican field in the sait with donald trumstatewith donal. I think hes the most mature guy, the youngest but the most mature. Hes not shouting, yelling and he knows his stuff. Bringing america back to what it was originally, fixing what is wrong. Sounds like donald trump. No, hes too hotheaded. The florida senator is hoping for second place in front of true. That gives him the opportunity to continue to fundraise, to continue the try to run a Strong Campaign in the supertuesday states. Hes touting an inclusive ine brand of conservatism. To become the president of the United States. Did they just have a game on the score board or is that the 45th president of the United States . Both marco rubio and nikki haley, mentioned as a possible Vice President ial pick. John. Lisa, thank you. Republican joe watt scins a wata former you white house aide. Joe take a look at this lates poll from South Carolina, from mon monmon moth university. They choose donald trump way out in front 35 to 19 or 17, depends on whether its cruz or rubio. It seems to me this poll shows just how close it is for second place, right . Oh yeah, second place clearly is a very hot race right now. And although ted cruz is trying to mix it up with donald trump. It really is going to be a race between marco rubio and ted cruz. Especially with the endorsement of nikki haley. Ted cruz has raised a significant amount of money for staff people and all those important states for supertuesday. You still cant discount that. Even if he comes in third in South Carolina hes still going to be aforce to be reckoned with come supertuesday. And jeb bush rave raised a lf money. In South Carolina, donald trump has really gone after jeb bush and the bush family an senator Lindsay Graham who supported bush. Just take a look at what trump said about Lindsay Graham. You have a guy hes one of the dumbest human beings ive ever seen. I saw him on television and i think he lost it. He said donald trump, he couldnt even speak, he back shaking. He went donald trump, ah ah ah, nut job. He knows so much about the military . I could push him over with a little thimble, boom. What do you say about that joe . Well normally in a political cycle, that kind of a response would not help a candidate. But donald trump has done extraordinarily well. Ive been saying since the summer now, that donald trump is a candidate to be taken seriously. Right now, if you look at all the polling data hes very well positioned to be the front runner as we head towards the nomination process. Hes positioned to win South Carolina substantially and to do very, very well on supertuesday. Hes in great position now and its really his race to lose. Lindsay graham apparently hasnt helped jeb bush, if you look at the polls, Lindsay Graham, he was wooed by Family Members, apparently george w. Bush and his wife laura has tried to convince nikki haley to go with jeb bush but shes gone with marco rubio. What do you think thereafter . That perhaps rubio has more momentum, clearly jeb bush has somebody that have executive leadership, having been the chief executive of florida for two terms, despite fact his father was president and brother was president , he himself has been chief executive but thats not playing well. If he comes in second or third in South Carolina, that will be a big victory for him. If he comes in fourth that means hes still in contention. I expect he has to there were rumors today and you know, political rumors a dime a dozen but there are rumors that jeb bush might get out and throw his support to marco rubio. Is that a logical scenario in your mind . Well, all things being equal it would seem that he would support marco rubio, who has been for whom he has been a marco rubio was a protege, the reality is that im not sure that given some of the bad blood between the two of them, that jeb bush would pull out of the race at this juncture still having significant money in his Political Action committee and throw support behind marco rubio. Its possible some point he could but im thought convinced woe do that. Im not convinced that one he would get out so quickly and two, im certainly not convinced he would throw his support behind marco rubio. The longer he stays in this race, lets play this out, doesnt it help Donald Trumps campaign every single day . Hard to say. The nomination is about delegates, amassing enough delegates to become nominee. If you have a candidate that does well but doesnt alast enough delegates to be the partys obvious nominee then theres always a chance for a brokered convention. If you are still able to stick around through march and april and still be a contender and in the game, you have a chance of being at the brokered convention. The thought is to stick it out be there for a long haulen there there for the voters and the delegates you amass. Thats the most important thing in this business, well be looking at who has the most delegates in march and april, may and june. Well talk again, thanks very much. Thanks john. With the mother of sandra bland, the woman found dead in a texas jail, last summer, clinton and Bernie Sanders are battling for crucial minority voters. Ashhar quraishi reports. Reporter at a rally to get out the vote in the citys historic bronzeville report, Hillary Clinton finds support from a mother. I present to you Hillary Clinton, our nations next president. Arrested in Waller County texas, later found handing in her jail cell. We owe it to them to Reform Police practices, to maim sure that no other young woman like sandra bland is ever pulled out of a car for no good reason and thrown into a jail, where she is found dead. Reporter while clinton is polling strong with chicagos black voters, some are still on the fence. My mind is not with it but i feel her heart is in it. After a double digit loss to Bernie Sanders in New Hampshire, clinton is looking to shore up her support in black voters. To outline what i intend to do to break down the barriers, its important that we look at everything that holds people back, and yesterday my poor emphasis ant commitment was to hold down the barriers of African Americans. Both clinton and sanders were criticized by the black lives movement. Last weeks milwaukee debate she rebuked sanders for not standing staunchly with the president. Today senator sanders said president obama failed the president ial leadership test and this is not first time that he has criticized president obama. In the past he has called him weak, hes called him a disappointment. One of us ran against barack obama, i was not that candidate. It is a strategy some political watchers say could help her in the political primary a month from now. Its not lost on the black americans that he chose her to be his first secretary of state. So that association is very strong, very wise strategy for her to hue closely to the president s agenda and to hue close to the president s policies. And there is a winning strategy. Reporter for now, clinton maintains a huge edge going into the next primary. Unlike earchl america african a, its important for the democratic candidate to be well beyond the primaries. Ashhar quraishi, al jazeera, chicago. The Nevada Democratic caucuses are just three days away, the polls show clinton and sanders locked in a tight race. Both candidates are courting the latino population, tristan atone reports. Our culture is the lake. Thats where we get our culture from. And so we do everything we can to protect our water. Reporter autumn harry is a member of the lake hear payute tribe. It would be great to come to our reservations and come to our communities to actually see what were trying to protect and what we want them to invest in. Reporter native people make up less than 2 of nevadas population, spread across 32 tribal communities. The voting block is so small that useful data barely exists. What is known is native americans have at a the lowest voter turnout of any group in the United States. If candidates don voters doesne candidates dont visit. Our messages are never brought up. Cody and her sisters, are enlisted in a program for aspiring native activists. They want programs that speak to them and their issues. I think we do have a sort of a different perspective on voting. Theres life after us, that we need to be thinking about. And its a lot more urgent than other people might feel. And i think that does affect our votes. Reporter what are you hoping to hear from candidates right now . I think that they can do a lot more. Especially in meeting with tribal leaders, and establishing a dialogue between them and the tribal leaders. One thing i know, we keep politics, money and church out of the office. Reporter we asked Charlotte Mann to break her no talk of politics rule. She was styling elaine duncans hair at the salon she owns on the pyramid lake payute reservation. Anyone that is currently in power that would visit our people, i dont feel were part of the political process. High reply held tribal lands and years of december enfranchisement. A nightmare for native american voters. Hello senator sanders. The irony native americans in swing states like nevada could be key in deciding a president ial election or who wins the caucus if the candidates reach out to the voters and they get to the polls. I think bernies ideology is similar to our communalism or tribalism. I think bernie is like a warrior for our people. Try to recruit caucus voters. We should at the very least peerpt in the system if theyre going to give us a shot to change it. We could be a deciding factor and thats really important. Reporter some have political reasons not to vote at all like cody. He prioritizes his tribal leadership ahead of american leadership. Is he good to affirm rights to Self Determination and coloniacolonialization. Is anybody even thinking republican . No about. Why not . None of the republican candidates what they stand for are in line with any of my viewpoints. Just ideology and that leaves Hillary Clinton and Bernie Sanders vying for attention even if there are questions about their sincerity. The challenge now, how to get the vote out in communities that have traditionally been excluded. The elk river Chemical Spill in west virginia. Freedom industries was blamed for that leak. Today, the companys former president was sentenced to 30 days in federal president with six months of parole to follow. Robert ray is in west virginia. Robert. You know its all over for former president of Freedom Industries, gearp gar gary soutt that doan mean th doesnt mean e residents are happy with the sentence. He pled guilty to the Chemical Spill, forcing tap water to be shut off for 300,000 residents. Tell me do you think the state of the people of charleston, i know this is a nervous day for you but is there anything you can say to us . Nothing at all, sir . Dont you think you owe it to the people of charleston just to make some sort of apology or comment for 300,000 people that couldnt drink water, dont you think . Dont you think sir . Sir . Cant you answer . Cant you answer the questions . Can you answer the questions . After nearly two hours inside the courtroom a federal judge handed down southerns sentence. He will spend 30 days in federal prison if florida . , have six months of supervised release and pay a 20,000 fine. Federal judges have now sentenced, southern was the last, the others received sentence is ranging from probation to fines to 30 days in jail. But many residents and local Officials Say the sentences are too light. To me it does seem like a slap on the wrist. And it was disheartening to hear that he was taking a private plane back to florida while he coughecaused a lot of devastatio the community. I have mixed feelings. Southern had faced the harshest penalty to all the officials. Up to three years in prison and 300,000 in fines. Federal prosecutors recommended a sentence of 21 to 27 months and Freedom Industries which filed bankruptcy was fined 900,000. The judge said it was symbolic because the company doesnt exist anymore. John, the judge also said that gary southern was not a criminal today. We should point out these were misdemeanor charges these executives were at and thats why these sentences were so minimal. The 20,000 fine, the 30 days in a minimum security prison. We should also note that gary southern today in court did apologize not for the Chemical Spill but for his behavior, when before the press corps he stood with a bottle of water, all the while the residents couldnt drink it, he said he wasnt feeling well and he cut the press conference short. Thats what he apologized for. He took a private plane back to his residence. John. Thank you robert. Coming up the popes visit to a Mexican Border city, juarez, where the crowds have been following the pope and his mass tonight, where it has been completed. Large crowds lining the roads to get to see pope francis. Plus, my conversation with the brother of ted kazinski and how he became the unibomber. Pope francis completed his visit to mexico tonight with a politically charged visit to the border. The pope prayed, laid flowers at the border in honor of those who died trying cross it. Howheidi zhoucastro is in mexio tonight. Heidi. The pope issued his blessing across the International Boundary through the border fence and to the community in the United States which he turns was one family with the brothers and sisters here in juarez, mexico. The pope matched that symbolism, that image equally strong with his words, directed at the migrants who made a perilous journey to reach the United States. Translator a step, a path, loaded with terrible injustices. Victims of slavery of kidnapping and extortion. Many of our brothers and sisters are the products of human trafficking. Reporter and the pope called for compassion for the hundreds of thousands of Central Americans who have made that journey. And he also compared them, the polite of those Central Americans to refugees around the world, calling the Current Situation not only a humanitarian crisis john but a humanitarian tragedy. Did he also talk about the violence in juarez . Reporter certainly that has been the other message he has been sharing on this trip to mexico. Today in his mass saying that it is 00 not to be complacent, that it is time for change here in juarez which just until recently was known as the mow dangerous city in the world most dangerous city in the world. In juarez more than 100,000 people have died in the last years from drug wars. The pope is says it is now time to publicly denounce the drug trade. Its hard to measure crowds but can you give us a sense how many people turned out for this . Reporter i think its easy to measure when you cant move your elbows, john. This place was packed. Im hearing just 200,000 people filled this viewing area alone. Not counting the hundreds of thousands more who lined the streets of juarez waiting to catch just a glimpse of the pope and of course, on the u. S. Side there was the Sun Bowl Stadium that also filled with spectators trt americafrom the american si. Heidi zhoucastro, thank you very much. Now to the South China Sea, where it appears that the chinese has deployed missiles on undisputed lands. Jamie mcintire has more from the pentagon. Reporter john, the timing would not seem to be a coincidence, coming as it was three weeks after choifn disputed a sailby by a u. S. Ship, and president obama convened the meeting of Southeast Asian countries. On woody island, china claims as its sovereign territory. Woody islands is one of the parasails, an archipelago in the South China Sea which china, japan all claim. A range of 125 miles, drew an immediate rebuke from the u. S. Which says putting military hardware on a disputed island, rebukes a statement made by xi jinping last year. When president xi stood in the rose garden, he said china will not militarize in the schiepts. Thersouthchina sea. But there is evidence every day of militarization of one kind or another. Within 12 nautical miles of another island, to challenge chinas Excessive Military claim. China argues that it has every right to set up what chinas foreign minister called limited necessary and self defense compounds. Territorial claims in the South China Sea, which also includes building up reefs and converting them into man made islands. The u. S. Takes no position on the sovereignty disp
