What their scandals and responses say about all of us. And see something, do something. A new group helping ordinary people perform extraordinary acts for strangers. Were going to meet the 22 founder of todays big idea. First, though, we start with that deadly shooting in florida. Police are right now trying to figure out why a gunman shot and killed six people at an apartment complex overnight. Two other hostages were rescued by police. Very bad night for these people in this building, for this neighborhood. I mean, it was very scared and they had every reason to be. But everything ended eight hours later but it did end with the shooter being killed by police. Nbcs mark potter for us right now near miami. Mark, for of all, what can you tell us about where the investigation is . The investigation is under way, although we are told that soon, within half hour, we will hear a statement from the Police Department right behind me here from the spokesman right at 2 30 eastern time. At least thats what hes saying. Let me show you the scene here. This is the fivestory Apartment Building in a working class area right near miami where the incident began around dinner time yesterday. It came to a conclusion in the wee hours of the morning today when police shot the gunman. Now, what were able to put together so far unofficially from talking to police, to witnesses, and a family member, is that this may have been b a dispute between a tenant and the management here. And that led to this shooting. And what we are hearing again unofficially from witnesses is that the older couple managing the building went to the apartment of a man living there with his mother, a man who had been a problem in the apartment for a while. They registered a complaint. There was a discussion, and as they turned to leave, were told the man opened fire killing them in the hallway. He then again, according to witnesses, ran to the side of the building downstairs, shot across the street and killed another man who was there with two children. Went back into the building, up stairs to another apartment, broke into the apartment of a man who was also a Maintenance Man here at the building, killing him, his wife, and the mans stepdaughter. Then went to another floor, another apartment, broke in, and held two people hostage. The police by then had arrived. They tried to negotiate with him. We are told at some point a decision was made that that was going nowhere. That the couple was in danger. They opened fire and killed him. And now were waiting for the official details again within half hour. Craig . Mark potter for us. Keep us posted after that news conference. Thank you, sir. To political headlines now. Nbc news has learned president obama will go to capitol hill wednesday to meet with house and senate democrats. Theyll talk about the economy. President obama will also hit the road again next week touting his plan to help middle class americans which he touched on in his weekly address. Over the next several weeks, in cities and towns across the country, ill continue to layout my ideas in each of these areas, because reversing the forces that have conspired against the middle class for decades will require more than shortterm thinking. It will require a longterm american strategy based on steady, persistent effort. In the republican weekly address House Majority leader eric cantor linked obama care to one of the most unpopular groups in america right now, the irs. They want to make sure the americans know the irs is responsible for implementing part of president obamas health care plan. On top of the negative economic and Health Consequences of obamacare, the law we requ e requires an unholy union between the irs and your protected health information. Recently all of us have been finding out more about the irs, its activities, and its databases. The Doctors Office is the last place anyone would ant to find the irs.

So how big does a scandal have to be to push a politician from public life . This week we were treated to two such spec tabls. New york mayoral county Anthony Weiner with his wife by his side saying he is staying in the race despite new revelations about sex messages to a number of women long after he had claimed to have changed. Meanwhile, san diego mayor bob filner went public after seven women accused him of Sexual Harassment despite pressure from democrats to resign, he announced he would begin two weeks of intensive therapy for his behavior but would not quit. Malika henderson is here from the Washington Post. Dive weigel a mr. A. Political reporter for slate. Com and msnbc contributor as well and Alexander Burns is at politico. Good to see all of you on a saturday. Malika, we like the new specs. Nice look. Well see. We will start with you first. Weiner has been desperately trying to focus the campaign on the issues. This is the reaction that he got from one resident in particular. The matter which you find yours, my job would have been gone. In the privacy of my home. I respect that. With reactions like that, dave weigel, do you think that he can stay in the race and be competitive . We can stay in the race because what is his option if he drops out . Further disgrace, further humiliation, even probably lower earning potential because he had been doing well and his wife had been doing well as consultants using connections when everyone had forgotten about them. I think look, this is a guy who feeds off attention. I dont think we need to provide yet more evidence. He probably will soon that he feeds off of attention. Hes going to slug it out until the september primary. And if he gets into the runoff, i think democrats would appreciate having him around and having him as an embarrassment. Hes the one person anyone in the field can defeat. But you saw huge if you look at the polls of this week, a huge dropoff from people who had been forgiving him for the scandal. Not just beating him down by nine points but favorables had been ticking up. People had been buying the narrative his marriage had been solved and they had gotten passed their problems. Being told they were all lied to by the weiner family, 20point dip in his favorable numbers. I dont think he will recover from that. Malika, there is, of course, a long history of publicized sex scandals involving politicians but the weiner scandal, even though it involves virtual relationships, so to speak, its stunned Many Political observers. Just one of his explanations this week. Take a listen. Its not dozens, just like i told the post who made a big headline out of it. Its not dozens and dozen, it is six to ten, i suppose, but i cant tell you absolutely what someone else is going to consider inappropriate or not. Were they sexual . How many conversations did you have with women after you resigned that were sexual in nature . I dont believe i had any more than three. I dont believe i had any more how effective has weiner been at just pure damage control . He hasnt been very effective. His first big pitch at damage control was that People Magazine article and the New York TimesMagazine Article after that. I think that was in april or so. But as dave said, he has been unable to sort of stanch the flow of this because he crafted that as sort of im a newm man now and my marriage is perfect. We know that isnt the case. To her credit or disgrace, however you want to see it, and i think women see it in different ways, stood up for her husband in that unbelievable press conference and essentially said i trust him. You should trust him, too. Its hard to see him rebounding in the polls. Again, i think one theory of the case is that this is his attempt at sort of cleansing the pallete, getting all of this out of the public system and then even if he loses, perhaps he can resurrect a career sometime later. Alexander, malika just mentioned huma, lets talk about her. Former Hillary Clinton aide. Shes been brought at the forefront of this. Lets listen to what she had to say. Here it is. Anthony has made some horrible mistakes, both before he resigned from congress and after. But i do very strongly believe that that is between us and our marriage. We discussed all of this before anthony decided he would run for mayor. Alexander, is her motivation purely political or is there more to it than this . Well, craig, obviously i would hesitate to try to read her mind but i do think that she had ended up in a situation thats probably a little bit more precarious than the traditional political spouse dealing with this scandal. As nia just mentioned she was an essential part of putting forward this good face to the world, that anthony is a changed man, our marriage is doing just fine after he resigned, he really got his act together. You know, weve learned now that is very, very much not the case. And i think that clip you played before where he was saying, look, there may be six to ten women but who knows how people are going to define whats inappropriate. Theres clearly more that could come out. So, you know, huma has now put herself in a position of being a character witness for a guy who clearly doesnt have the record to back that up. Dave, your take on this is especially unique. Huma abedin, a lot of comparisons between her and Hillary Clinton. You write, though, quote, the weinerabedin marriage is to the clinton marriage as shark nato is to jaws. How are they how are they different, dave . One sharknado difference before it was banned from pop culture. Theyve been compared for years to the clinton marriage. Huma abedins political career was based on years as body man and adviser to Hillary Clinton. In this campaign reported widely the one reason weiner was doing well is that huma was lining up donors with the message that whatever you think of my husband, whatever you think of his chances to win, if you ant to keep on the clinton train you should probably help and donate to this campaign right now. They have been compared to, you know, another couple with a very public marital struggle with the difference being the clintons are respected by liberals because theyre uniquely politically talented. Hillary clinton was getting a lot done in her 20s before she settled down in arkansas. Abedins reputation was inflated for reasons not clear to us who are not in, quote, unquote, this town. I think in that press conference, now shes asking for us to forget how she was asking for us to adore their marriage and what they had put together and then to consider it to be private again. I dont think that holds up. I feel like a lot of sympathy for her which was based on very little faded away this week. Before we get out of here i dont want to forget the west coast. Bob filner under pressure to get out after several accusations of Sexual Harassment. Four women came forward on local tv thursday alone to accuse the mayor of inappropriate behavior. A total of seven have gone public. Theres a 1800 number thats been set up for other women to call in. This is what the mayor said yesterday. Beginning on august 5th i will be entering a behavior counseling clinic to undergo two weeks of intensive therapy to begin the process of addressing my behavior. During this time period i will be at the clinic full time. Every morning and evening i will be briefed on city activities. How can bob filner not step down at this point . Its going to be tough. Youve got these recall efforts that are out there now. People questioning whether or not you can only spend two weeks in therapy and then be cure of this habit. You would think it would take longer than that to be cured of an addiction to chocolate. So he has a real problem here. You have the head of the dnc calling for him to step down. Hard to see how he weathers this. He is testing the limits of the publics acceptance of this. Are they going to get enough signatures . I think they need 100,000 in the next 40 or so days to mount those recall efforts. Well see. Big thanks to all of you. Thank you. Coming up, the fight for black men and boys. We cannot let this happen to anybody elses child. Recent events have sparked major conversations in this country on race, justice, and t voting rights. Where does the conversation go from here .

Shutting down the government just because im for keeping it open, thats not an economic plan. Threatening that you wont pay the bills in this country when weve already racked up those bills, thats not an economic plan. Thats just being a dead beat. A dead beat. That was president obama in florida thursday. It was one of several speeches that he gave on the road addressing the economy and the middle class. Hes got more schedule tond horizon. Whats the message . Joying me now is former Obama Administration economist and contributor bernstein and economics officer and cnbc contributor. Ron, i want to start with you. Right off the bat here. What kind of tangible effects is president obama hoping to achieve out of these addresses and real liistically what can ho without Congress Help . List executive orders to allow for some projects to go forward. I dont think given the inability for the Immigration Reform to go forward, with respect to infrastructure and education, are going get a broad hearing in congress, particularly in the house. So while he sounded out these things before and i dont dit disagree that we need improvements in education, we need a massive overall of the grid, as its called, as trillion dollar project that should be undertaken. I dont hold out a lot of hope that well see progress on this front any time soon. So then what happens to the grid . Well, listen, the grid is being billed out in private sector activity and in being improved slowly. But as a National Infrastructure program and ive been talking about this since 2009 and girard knows this very well. I think the government should spend the trillion dollars with a 6 yield on the bonds they use to borrow the money. Investor, bank, Insurance Companies would buy those. It will become a capitals asset of the government that draws an income as opposed to expenditures that would tilt the fiscal balance in an inappropriate way. The president gave these addresses wednesday in illinois where he also spoke when he was a u. S. Senator. You wrote object this. You write in part, quote, what is different is that in 2005 he was saying, heres what a president should do. In 2013 hes saying, heres what i would be doing if we had a functional political system. He still sees a clear role for government in the economy but he now sees Something Else that he could not t have foreseen eight years ago. The political barriers to ifr memem implementing that vision. Why is the president putting so much focus on the republican roadblocks and when he does that does he risk losing the support of continuing the strategy of beating his head against the wall on this . I dont think that he loses support. He doesnt have much support to begin with on this stuff, especially from House Republicans as monday ron just mentioned. He has lots of support from democrats both in the senate and the house but theyre not enough to move legislation. I think the reason one of the reasons you hear him going where hes going comes from the clip that you played to introduce this segment, where he wants to make very clear to the American People who are the obstructionists who are standing between them and at least, as he perceives it, their employment and their opportunities. And by the way, i think hes right. A very good idea like you just heard ron articulate takes advantage of the fact that theres a lot of infrastructure that needs to be built out in this country, the cost of borrowing is quite low. The president just like he did eight years ago has the correct diagnosis and the correct prescription. As i wrote earlier in the week, the political barriers, the obstruction is whats holding him back. Ron, lets talk about the middle class in this country and the simplest of terms, no spin here. Just facts. What has happened over the past few years, over the past decade or even 20 years, whats happened to the middle class in america . A lot. If you want to go back 20 or 30 years and you talk about globalization does have the benefits to the macro economy. Textiles have left the United States for a period of time like auto manufacturing and a whole host of other industries. That because of these free trade agreements, weve seen jobs leave and go to plac
