Good morning. Im steve kornacki. We are 152 days and counting now until election day. Topping the agenda right now, the big meeting. President obama set to sit down with Bernie Sanders just over two hours from now. This as the Democratic Party tries to move on from its primary season. It was a healthy thing for the Democratic Party to have a contested primary. I thought that Bernie Sanders brought enormous energy and new ideas. He pushed the party and challenged them. I thought it made hillary a better candidate. What are they going to talk about in that meeting today . Could it be the beginning of the end of sanders bid and the start of Democratic Unity or something else. Sanders on board the plane now to washington. Chris jansing was with him and with his Campaign Last night. Brandnew information from her on how the Sanders Campaign is reacting to what obama said on the tonight show last night and what theyre expecting out of that meeting just two hours from now. Also on the agend areports that Elizabeth Warren is ready to get off the sidelines and endorse Hillary Clinton. Warren has been one of the sharpest critics of donald trump so far. A small, insecure money grubber who doesnt care who gets hurt so long as he makes a profit off it. What kind of a man does that . A man who will never be president of the united states. Warren has been the lone female senator not to endorse Hillary Clinton in the primary process. This another sign of a Democratic Party trying to come together after the primaries come to an end. When will warren do it and why did it take her so long . That is still ahead. Rounding out our agendjengendag republicaning wondering if its too late to dump donald trump. Official he hes not our nominee. That wont happen until the middle of july. I want to make sure he renounces what he says at least in regards to this judge. Donald trump trying to shut down talk like that. First with that subdued address he gave on tuesday night. Now today, hes going to be meeting with Top Republican party donors. Well have all the details on that and much more still ahead. Were going to begin with our top story. Bernie sanders about to get on board a charter plane in burlington, vermont. Hes going to fly down to the Nations Capital to washington, d. C. And there he will meet at 11 15 in the morning in the white house with president obama. And the president had been eager, it seems, to endorse Hillary Clinton as the Democratic Partys presumptive nominee, but he has remained on the sidelines throughout the primary process trying to be neutral. The president saying last night on the tonight show with jimmy fallon with clinton officially clinching the nomination this week hes going to encourage a quick end and an endorsement from sanders today at that meeting. My hope is over the next couple of weeks were able to pull things together. And what happens during primaries, you get a little ouchy. Is bernie going to endorse hillary . Im sure theyll have a conversation. Is he ever going to drop out . Is he going to stay in and im going to be talking to him tomorrow. Hes going to be coming to the white house. And the main role im going to be playing in this process is to remind the American People this is a serious job. This is not reality tv. Nbcs Chris Jansing was on board the plane yesterday with Bernie Sanders getting a read on how theyre reacting to all of this. The meeting is about two hours from right now. We know this is a meet, sanders and obama, done at sanders request. What do we know about what Bernie Sanders wants to talk about . Whats going to be discussed here . Lets make no mistake. This is a pivotal meeting. And Bernie Sanders and his senior staff, some of the other Staff Members ive talked to, have been extremely appreciative of the public stance of president obama. That he has gone out, as we heard him on jimmy fallon, praising what he has done what sanders has done in this campaign. And notice the word he used that over the next couple of weeks. Thats exactly the wording that ive heard from two senior staffers over the last 24 hours that this is not a decision. This is not a move thats going to happen overnight. Hes not going to come out of this meeting today and suddenly decide hes going to drop out of the race. He is committed to tuesday, which is the primary here in d. C. He has a rally here tonight. Having said that, these discussions have gotten under way. What he calls the assessment period. After what happened in california, after what happened in those other states, he walked away with just two of the six states. He had hoped it would be the other way. Now he really has to look and see how does he move forward . So thats going to be a focus of this meeting. What is at stake here . Obviously, for the president , its making sure that his legacy is assured. That he is able to see that we have a strong they have the strongest possible candidate. Ive been told to move forward. Having said that, this is a very delegate dance. Yesterday we saw Bernie Sanders seemed to be getting tired. Didnt want to speak to the press, which is highly unusual. Local press was there. He talked to some supporters gubugot back in his car and left. Then called his senior staff. There was a meeting at his house last night with the senator and jane sanders. Jeff weaver, his campaign manager. No readout on what exactly happened in that meet, but we do know whats really important to him, and you have to believe its going to be a topic of discussion here is what he wants in terms of the platform. We have a list. Some of the things that ive been told are very recently are really priorities for him. The minimum wage, family medical leave which is a bill that kefrten gillibrand has. Big bank reform, expanding health care. Free Higher Education and fracking and a carbon tax. This isnt going to be easy. Its not going to be quick. But this meeting could set the stage as could the meeting with harry reid this afternoon because that would be about what his role could be moving forward in the senate. He still has a couple of years on his term. Such a delicate dance for democrats. Neutral, maybe like the president has been, trying to get Bernie Sanders toward unite with Hillary Clinton. How they talk about the next few weeks and whats ahead for Bernie Sanders is key. Vice President Biden was asked this question yesterday. Let me play that and ask you about it. Mr. Vice president , can i ask you is it time for Bernie Sanders to drop out of the race . Be a little graceful. Let the man have his own pace. I think Hillary Clinton is going to be a great president. Obviously very intentional trying to show public respect for Bernie Sanders. Yeah, he wants respect, and he wants influence. And thats where harry reid comes in as well. He really likes joe biden. He really likes harry reid. One of the senior staffers told me every other week he was in the senate saying i really loved harry reid. Even though they had that flap over the nevada convention, they have a Mutual Understanding and a mutual respect. And this is something that happened has happened every time before when you have a race like this. Happened to Hillary Clinton. Took her a couple of days to come around to the idea that she needed to drop out. But also remember, this is a very different situation. First of all, Hillary Clinton had been a Democratic Party insider. Hes been an independent, a socialist for his time throughout the senate, even though he caucused with the democrats. She wanted to run again. Thats not going to happen with Bernie Sanders who is 74 years old. So theres a little different trajectory here. He also feels a real affinity for and with the 10 million 10. 5 Million People who have voted for him. The 1. 5 million who have come out to these rallies so far. The 8 million or more individual donors have given to his campaign. So what does he have that they want . One, the support of those voters who really love Bernie Sanders. And secondly, he has a list, a very valuable list so far. Hes only used it to the benefit of a handful of down ticket folks, steve. Chris jansing at the white house. That meeting two hours away. Bernie sanders sitting down with president obama. Chris, thank you for that. Hillary clinton, meanwhile, is going to try to follow up that speech she delivered against donald trump last week on the subject of National Security with one about the economy and donald trump. Telling the wall street journal, he may have some catchy sound bites, his statements on the economy are dangerously incoherent. Clinton also expecting to receive the endorsement of senator Elizabeth Warren shortly. Sources telling nbc news the announcement could come as early as monday. Let me bring in Kristen Welker at the white house. We say as early as monday, but the story with Elizabeth Warren in endorsing Hillary Clinton is this is very late. This is midjune. Every other female democratic senator for instance endorsed Hillary Clinton at the very beginning. A big show of unity at the start of this campaign. Elizabeth warren was the lone holdout. Conspicuous then. Whats taken her so long . Elizabeth warren, of course, is a progressive fire brand. She is someone whose ideals line up very closely with senator sanders. At the same time, shes the only female senator who hasnt endorsed secretary clinton. Shes wanted to walk a very fine line, steve, for this very moment. So that she hasnt alienated any of senator sanders supporters. If she and when she does endorse secretary clinton, shell do it at a moment this race is over. After all of the votes essentially have been cast and secretary clinton has officially won her partys nomination. That will put her in a stronger position to really try to rally some of senator sanders supporters. Right now about onethird of them saying theyll not support secretary clinton. So the timing of this so incredibly critical. Weve been talking about the delicate dance thats going to happen at the white house. Its similar for senator Elizabeth Warren. Weve been watching her closely. Shes proven to be one of the more effective attack dogs against donald trump. And were told at an event in d. C. , shes going to have more strong words for him. Let me read you a little bit of the excerpts were getting that we expect to hear from senator warren. In one she says paul ryan condemned Trumps Campaign for its attacks on judge curiels integrity. Great. Wheres his condemnation of the blockade, the inn timidation smears. And then shell use the term racism. Donald trump chose racism as his weapon but his aim is exactly the same as the rest of the republicans, pound the courts into submission to the rich and powerful. Now as all of this unfolds in this very big day at the white house, theres increasing buzz about whether the Clinton Campaign might have Elizabeth Warren at the top of its list for potential vp pick. Shes not ruling her out. Senator warren not ruling out the possibility as well. But, of course, the question, is the country ready for two women on the top ticket . Well have to see. Some strong words expected from Elizabeth Warren as shes poised to endorse secretary clinton. Kristen welker at the white house, thank you. Joining us, congressman peter welch from vermont. He supports Bernie Sanders for president. Thanks for joining us. Let me ask you. You are a brs suppopercent perc suppoBernie Sanders supporter. Are you at a place now where youre ready to say, been a Great Campaign for Bernie Sanders but im going to endorse Hillary Clinton . I think vice President Bidens got it right. Lets have a little grace here. Lets give bernie the time and space he needs. Bernie is a very pragmatic person. I knew him when he got elected mayor in 1981. Beat a democrat by ten votes. Youd have thought the sky had fallen. He was a socialist then. When he became mayor, he paid attention to the things that need to be done. When it snowed he plowed the streets and focused on keeping property taxes low. He worked with developers on projects important to the city. Hes an Incredible Campaign are with fierce rhetoric and commitment and a practical person who knows what the real situation is. His goal, obviously, and i think rightly so is respect for what hes accomplished. He really sent a jolt of electricity through the Democratic Party. In respect for the folks who have worked so hard for him. A couple hundred million in small contributions. I think its about 12 million votes. Hes got to stay involved. We need humim. The party needs him. Were just finding a way that can be done in a really effective way. When you say respect, what exactly is that going to mean . Respect, i think, for bernie is about acknowledging the importance of our party to commit itself to economic, social and environmental justice. You know, bernie is not looking for something for himself. Hes not a transactional politician. Not like he wants a k street lobbying job. He wants the party to stand up against the 1 , to jolt this country out of its were this wh stagnant economy is accepted as natural law. It happened as a result of policies we have to result. Thats what bernie has so effectively talked about. Thats the dream he does not want to die. What about the process here itself . The primary process. Weve heard so many complaints from him, from his supporters about the superdelegates. Hes still talking about them right now. Party leaders, like you, elected officials who automatically get to vote at the convention. At the start of this proercess, not a single vote was cast and 400 superdelegates were already on board with Hillary Clinton. Is he going to push to get rid of superdelegates Going Forward for the Democratic Party . Im not sure whether he will. Im not a huge fan of superdelegates. It creates a dissidence with the rank and file folks who vote. But i think the issue for bernie is going to be less about process, less about who is the head of the dnc and whether and how we have superdelegates. I think hell focus to some extent on that but whether the party itself is going to mobilize to fight for economic, social and environmental justice. This party, by the way, Hillary Clinton has done a good job embracing much of the sanders message. Shes done a great job that she genuinely respects what shes done. What were going to see as the best path for unity is respect for that accomplishment of Bernie Sanders and his support. Thats real. So its not a pat on the head situation. This is something thats organic to the future prospects of this party if were going to succeed in getting our nominee elected and this is a huge deal for democrats and bernie. He said on his her aor hillarys worst day, theyre 100 times better than trump. Congressman, thanks for the time. Coming up, with news about Elizabeth Warren getting on board with Hillary Clinton soon, theres the question everybody is asking now. We heard Kristen Welker talk about it a minute ago. Could there be a Clinton Warren ticket . Well look at some of the pros and some of the cons of putting Elizabeth Warren on the democratic ticket. Donald trump meeting with some of the Republican Partys biggest money people. Fundraisers, wealthy donors. This just one day after trying to back away from his claim that he would need to raise a billion dollars to win. Is he actually behind in the money game . Do you really know what it means . No. The answer is no. Because its complicated and sciencey. But with my nutrition mixes, you dont have to worry about the science. You can just put it in your pie hole. Planters. Nutrition starts with nut. vo on thtrane test range, you learn what makes our heating d cooling syems so reliabl if theres a breing point, wel find it. Its hard to stop a trane. Really hard.
