0 good morning from washington. it's june 28, 2013. this is "the daily rundown." in for chuck todd, who's traveling with president obama in africa. first, the big news on capitol hill. the senate has approved the most significant reform for the most imcombination loss in a generation. now it's over to the house. with all 100 senators present and voting from their desk and vice president joe biden presiding, the senate passed a comprehensive immigration bill. undocumented students watching in the senate chamber cheered the vote. >> yes, we can! yes, we can! >> sergeant at arms will restore order in the gallery. >> after the vote, republican members of the gang of eight urged the house to consider the bill. >> my father had someone actually phonetically write on a little piece of paper the words so their entire lives, this issue has been percolating. it's important for the house to do its own work. each committee that has a responsibility is working on yipds. you'll probably see more things that deal with interior enforcement, meaning if people overstay visas or work situations with things called e-verify. those things will be to the forefront, along with border security. speaker bainer is saying he wants a majority of republicans to be on board and, in part, that make as eventual bill, if ones pa, have some ownership for republicans too. we never saw that with the health care law. that's had so much citel is attached to it in part because they didn't have their fingerprints and their ownership on it. so we'll see what happens. it will be a longer fight but the house wants to have a sense of authorship on this. not just taking the senate's plan and voting on it. >> i want to follow up, because john boehner has made it clear he wants the majority of the -- to support any immigration legislation. i know we're only 15 hours removed from the senate vote. any sense that commitment is wavering at all among house republican leaders? >> i think this one test will be this week ahead with the recess for the july 4th period when members will be home. this is fresh on the minds of the voters. especially people who turn out at things like town hall meetings and local parades. is there something blowing in the wind, a sense of how republicans will vote. so much don't have a reason in their own districts to change their minds on immigration. but could there be a movement? they hope there is that sort of national conversation that creates more pressure and also the demographic sense in the country, looking to try to get on the right side of history as the country changes. we had one big victory in the senate side in terms of them accomplishing something. and now we've got to see how does the country feel? that's always a good gauge. >> a great point, kelly o'donnell, i hope you get some rest this weekend. gosh knows you've earned it. now to an nbc news exclusive. retired marine general james cartwright, the former vice chairman of the chiefs staff, has been notified he's the target a justice department criminal investigation into the leak of a covert soocyber attac. an investigation president demanded last year. nbc news correspondent michael i isokof joins me. what have you learned? i know you've been on it. where does it stand today? >> where we stand today is we have a very high profile target. what was really the most politically sensitive and closely watched of all these justice department leaked probes. this was one that went very close to the white house. in fact, there were a lot of very nervous people in the white house who retained counsel, who were getting questions about their contacts with david sanger of the "new york times" who broke the story about the stuxnet computer virus. the initial demands came from charges among republicans last year that this whole story was leaked by people, senior people, to sold of bolster president obama's national security credentials during the campaign, that this made him look forceful that he used this new form of sign warfare to disable the iranian nuclear program. i've spoke to a lot of people involved in this investigation. late last year, lawyers got word that the probe was moving away from the white house and into another building. that building turned out to be the pentagon, where general cartwright was vice chairman of the joint chiefs of staff. he was, by the way, very close to president. so this does go, in some ways, into the white house. he was one of the top advisers. he's now the target. he hasn't been charged, but he's clearly in the justice department's crosshairs right now. >> thank you. turning now to our friday daily rundown roundup of all things 2016. this week's historic developments on same-sex marriage, voting rights and immigration set the stage for the coming 2016 fight. it's coming sooner than you think. vice president joe biden voted for doma when he served in the senate and neither barack obama nor hillary clinton supported gay marriage during the 2008 presidential campaign. but if it wasn't already clear after this week, it definitely should be. support for same-sex marriage is an absolute prerequisite for anyone who wants a chance at the 2016 nomination. clinton who announced her support for gay marriage in march, welcomed the decision with her husband former president bill clinton saying, recognizes that discrimination against any group holds us back in an effort to form a more perfect union. in his audio series, the vice president, whose unscripted announcement a year ago that he was in favor of gay marriage pushed the president to announce his support days later, related the story of a gay friend and adviser whose marriage will now be recognized. >> americans are way ahead of their political leadership now. now we can look each other in the eye and say we're on the road to absolute fairness and equity. >> but though wednesday's rulings are further proof that oppose the right of gay people to marry is increasingly a losing political proposition, for republicans eyeing the 2016 race the issue on gay marriage is complicated. christie blasted the court's decision. >> i don't think the ruling was appropriate. i think it was wrong. i thought that justice kennedy's opinion in many respects was incredibly insulting. he basically said the only reason to pass that bill was to demean people. that's a heck of a thing to say about bill clinton and the republican congress back in the '90s. >> here with me now, nbc news deputy political editor. let's talk about first of all the sort of broad movement in the country. it's remarkable. we said in the opening that hillary clinton and barack obama -- they didn't support it till 2012, gay marriage. >> that's right. bill clinton, the person who signed it into law, and coming out with his wife saying that, you know, this is something that is akin to civil rights. so you have seen a major shift. but, you know, color us skeptical that politicians would move with the public opinion but that is what happens. i think democrats, you know, in supporting civil unions back in -- way back in 2008, you know, they thought that was one way that they could walk this line and say to gay rights advocates, look, we're on your side, but we just can't win if we're pro-gay marriage. now that's all changed. >> the thing that's important, we showed the numbers, nbc/"wall street journal" poll, 30% in 2004 favored same sex marriage. the number in those numbers. republicans remain. they remain opposed. and that's why it's such a tough nut for many people looking at the presidential race to crack. here's what moreco rubio had to say. this is about immigration but it's the same problem. you have conservatives. conservatives want one thing. the center of the country seems to be moving in a very different direction. let's play this rubio bite and talk more broadly about that. >> they love to focus on the politic, of all this. for me, this isn't about catering to any group for political gain. it would have been a lot easier to sit back, vote against any proposal and give speeches about how i would have done it differently. finally, this is certainly not about gaining support for future office. >> okay, everything is about some positioning at some level. this is the line. rubio, rand paul, on immigration, on same sex marriage. how do they -- you can't win the general election, right, till you win the republican primary for president. how do they do both? >> i think that line that rubio had in talking about, you know, it could have been easier for me to sit back and say how i would have done it differently seeps to be a little bit a shot at rand paul. >> cruz too -- >> i don't know if he's going to run for president. >> good point. >> i think you'll see rand paul and rubio potentially squaring off and you can see this debate on a stage we'll pay attention to. so i think that is a very difficult thing. i think he thought he could sell it to conservatives. he's tired of it and he's getting flack from the right. in that same speech, talk about all the things that are untruths in the bill and be a truth teller. >> he's having to do that and he'll continue to have to do it no matter where the bill goes. happy friday, thank you. up next, the house call, the fight to become the majority in congress. and we're keeping our eye on the courtroom in florida where the george zimmerman trial continues today. our legal team is standing by and we will bring you new news as it happens. plus, president obama is en route to south africa where nelson mandela remains hospitalized in critical condition. we'll go live to pretoria coming up. first, a look ahead at today's politics planner.
