fresh off a bruising -- what took place. night,ff a bruising bernie sanders went to a coffee shop for an historic scone. with president obama, saying that while he will be competing in the primary next week, he will ultimately do everything he can to stop donald j trump from becoming president. i spoke briefly to secretary clinton on tuesday night and congratulated her on her very strong campaign. i look forward to meeting with her in the near future to see to we can work together defeat donald trump and to create a government that represents all of us and not just the 1%. a couple of hours after sanders spoke came the big news of the day. the clinton campaign released a three minute video produced by them in conjunction with the white house of president obama expressing his unequivocal support of her run for the white house. mr. obama: i want to hillary clinton for becoming the presumptive nominee for president of the united states. i know how hard this job can be. that's why i know hillary will be so good at it. in fact, i don't think there has ever been someone so qualified to hold this office. she has the courage, the compassion, and the heart to get the job done. and i say that a somebody who had to debate her more than 20 times. i am fired up, and i cannot wait to get out there and campaign for hillary. john: in fact, president obama and hillary clinton are expected to hold their first joint campaign event on wednesday in green bay, wisconsin. thisresumptive nominee had to say about getting her old boss support. -- itlinton: it took some meant so much to have a strong, substantive endorsement from the president. aviously, i value his opinion great deal, personally, and has i have -- as i have said repeatedly on the campaign trail, i think he has been a successful president who has made our country stronger and fairer. over the years of knowing each other, we have gone from fierce competitors to true friends. john: big day on the democratic side of the aisle. what do you think the immediate implications are of this endorsement of hillary clinton in her effort to unify the democratic party? mark: it makes it much harder for bernie sanders to go forward in any significant way. it makes it much more likely the convention is united. it will be difficult for donald match.o she will raise a lot of money .ith the presidents help the coordination between this president and his chosen successor is tighter on a staff level van anyone -- than anyone in modern history. my understanding is president obama has been itching to do this. the president has wanted to endorse basically from that moment forward. he wanted to endorse sunday or monday, but he was deferential to what the clinton campaign wanted. be campaign wanted this to orchestrated in some degree of negotiation with the sanders campaign. they wanted to give sanders and time. even so, the urgency of this was high. hours after the big elections on tuesday, exactly where barack obama wanted to be, exactly where the clinton campaign wanted him to be, and senators sanders behaving in a pretty cooperative place. i don't think you could imagine is whole thing could have gone better from hillary clinton's point of view or the democratic to bes point of view where we are now just 48 hours after we got the results of the california primary. mark: no. it did not take long for donald trump to respond to the news of the presidents endorsement. he turned to his favorite medium microphone and tweeted this. clinton quickly tweeted back at trump what is considered by many millenial's to be the ultimate iss.ter des what are the implications for trump and clinton in the general election from this endorsement? wen: there was a long time all thought the republican party was in disarray and the democratic party would be united relatively easily. then, it looked like donald trump was uniting the republican party and the democratic party appeared to be in disarray. now the democratic party is moving toward unity and the republican party is exhibiting more lack of unity than it has in many weeks. bad for donald trump. the president has over a 50% approval rating. nothing about this is good for the presumptive nominee. if you are running to succeed a president of your own party, there can be to areas of psychodrama, one with the last remaining opponent, and one with the incumbent president. president obama today in one news cycle ended those two potential psychodrama's. john: and as you know, donald trump has been trying to make mischief for a while, suggesting sanders should run as an independent, should challenge hillary clinton. happen,ot going to obviously. it's all good for the democratic side and nothing good about this for the republicans. again, it's happened more quickly, and i think it bodes well. you will see hillary clinton get a polling bump pretty quickly as democrats begin to come home as republicans have for trump. if half of the bernie donors and half of the obama donors who have not given to clinton give to her, that is a serious bit of cash. and i think she can enlist bernie sanders before too long to help her raise money and put on donaldpressure trump. clinton will have bernie sanders, her husband, the the obama's, all out there for her. donald trump will have surrogates, but no one on the level she will have. john: having barack obama and bernie sanders raise money for you is a big deal for the clinton campaign. good for them and good for us. on hillarye more clinton next and what she said about elizabeth warren after this quick break. ♪ in off the campaign trail, bernie sanders had a busy day in washington, d.c. today. he talked about the economy. then he met with reporters and told them he would do whatever it takes to defeat donald trump in november. he then went to capitol hill and met with harry reid and chuck schumer, who is expected to replace harry reid the top democrat on the senate. tonight, sanders is holding a rally on capitol hill, leading washington,uesday's d.c. primary, in which he still says he is going to campaign hard even as he wraps up his campaign. what does he want and what can he get? john: we have come full circle on the sanders campaign. we are now back to the original impetus that got him into the race in the first place, which is to press forward on the progressive issues he cares about. he has convictions about how he wants to change the democratic nominating process, about same day, easy registration, open primaries, eliminating the role of superdelegates, and i think hillary clinton and the democratic party are likely to give him what he wants. they recognize that those things are necessary in the new age and they don't have a stake in holding on to the new system. mark: secretary clinton got to the campaign having finessed saying that he theyo liberal and that don't agree on anything. he has now gotten his issues into the party, raising it the minimum wage, reducing the influence of special interest money on politics. all of it. democrats take control of the senate, he has a good chance to be the head of an important committee. right. think that's he has always been a gadfly on capitol hill. he now has a lot of the democratic leadership who, if he handles this right, as he seems to be, right. by which i mean, bringing the party to gather instead of cleaving it -- together instead of cleaving it in half, he will have a lot of pull on capitol hill and be able to do more in terms of making policy then he has in his whole career in the senate. and it's possible the democrats will retake control of the upper chamber. ofk: there is a big meeting his supporters in chicago later this month. how does he want to go forward? how does he want to get his message out? big events? social media? how does he do it? john: hillary clinton is anticipating another big endorsement in the near future. massachusetts senator elizabeth warren is expected to back the presumptive nominee any minute now. her name has long been mentioned among possible running mates for hillary clinton. harry reid and others are for the idea of weren't being on the ticket. here is what clinton had to say today -- of elizabeth warren being on the ticket. here is what clinton had to say. i haventon: of course spoken with senator warren in the last few weeks. we have stayed in touch over the i am very much looking forward to having her good advice and counsel as we move into the general election campaign. i have the highest regard for her. tolso believe that my plan rein in wall street was the toughest, most comprehensive in this campaign on either side. i will be consulting with senator warren and others about how we are going to actually implement it. one thing i am particularly interested in, which i no means a lot to senator warren, is protecting the consumer protection bureau, and also protecting dodd-frank and the regulations put on wall street after the great recession from the promise to repeal them by donald trump. elizabeth warren is giving a speech tonight where she will escalate her attacks on donald trump and the republican leaders who still support him. after that, she will be on rachel maddow's show, where she is expected to offer her endorsement for hillary clinton. mark, my question for you, what obama's's developments, endorsement, sanders speech to the press, and elizabeth warren's-- elizabeth endorsement expected later tonight, what does all of that mean for the campaign going ahead? mark: elizabeth warren has been eclipsed by bernie sanders on the message. is has gone after trump and expected to go after paul ryan and mitch mcconnell. ryan's office has come back at her. thehas put herself in center of democratic heavyweights, right under the s, and clinton's. i don't think she will be on the ticket, but i think she will prove that she can raise money, get a message out, be an activist player on the national scale that she has been on a different level up until now. john: i have always believed that elizabeth warren could be on the ticket and i continue to believe she could be, and here's why. although bernie sanders is now moving into a position where he will be a unifier and not a divider of the democratic party, quite clearly, it still remains the case that a lot of supporters of bernie sanders will not necessarily do exactly what bernie sanders tell them just because he endorses hillary clinton area they will not necessarily flocked to her. -- hillary clinton. they will not necessarily flock to her. she has a problem of an doozy as in has to solve it. and a problem of enthusiasm she has to solve it. i don't think there is an easier way to solve it and elizabeth warren. mark: i don't think so. we'll see. ♪ now are twog us amazing people, jennifer epstein who interviewed hillary clinton just before president obama's endorsement, and bloomberg's senior white house correspondent and birthday girl -- happy birthday, margaret. you guys are both awesome. let me ask you this question. played a clip from your interview with hillary clinton talking about the endorsement. they are going to head out on the campaign trail next week, going to green bay, wisconsin. why green bay, and how does she feel about being on the trail with barack obama? jennifer: wisconsin is a state that trump wants to put into play. it is a place where both parties will have to campaign pretty heavily. she is trying to go after working class, white working-class people, and that's a good place to start. it's a specific town that -- city that donald trump has mentioned as a place that he wants to reach out to voters, so they are going. hillary clinton said to me she is really excited about it. she has come from having barack obama being her biggest rival to being friends with him. she is looking forward to having fun, joyful times on the campaign trail with him. also, keep in mind it's a state that barack obama won in fatah clean even though -- emphatically even though paul ryan was on the ticket and it is a state that hillary clinton loss to bernie sanders. , give us a sense of what the behind the scenes orchestration and drama was around senator sanders's visit to president obama. margaret: it was quite a choreography. we did know that senator sanders to thiscted to come out location. you could see the reporters gathered in the burning sun to wait. it was not clear until this morning when they began moving the press briefing back and back, and there was sort of a magic five in the air, that something was about to go down. this meeting, which sanders had laststed, was the remaining obstacle to president obama giving his endorsement. he wanted to on sunday. obama was prepared even before tuesday night, but certainly after tuesday night to get out with this and move things forward. it was the clinton campaign that wanted to wait, feeling -- and president obama understanding -- that senator sanders wanted to have his own time and space to make a decision that he has not articulated yet but that he is coming around to slowly but surely. it was a matter of giving him the deference of that meeting, talking about grassroots, talking about senator sanders's ideas, moving those forward, and president'st the experience being the presumptive nominee, what he needed from hillary clinton eight years ago, and how they could put mr. sanders in the best position to move things forward as part of the team. he is not quite there yet. talk about the human reality that the clinton campaign has that two of their top officials used to be among the top officials of this white house. jennifer: they have certainly been part of the conversations between the campaign and the white house, going back to before this campaign even officially launched. this dynamic of, you know there is a constant conversation happening. going to seee are this seamless cooperation wherever, whenever, however president obama can be used and michelle obama and the bidens to hillary clinton's advantage. this is about the legacy of all of the people in the administration being able to carry on and make sure that things like the affordable care act don't get repealed. that is very much where their priorities lie. is actingary clinton like the do factor heir apparent vice president. there is an actual vice heirdent -- de facto apparent vice president. there is an actual vice president who is having his own meeting with bernie sanders today. what will they do going forward? margaret: that meeting has been underway at the observatory. we will see later tonight, both by president biden and senator elizabeth warren, speaking at a gathering of progressive legal activists and lawyers -- we are not expecting either of them to make their endorsement there. we understand senator elizabeth warren will make an endorsement tonight. biden has a very special role. hillary clinton was best positioned against the republican nominee several months ago. he wanted to run himself. he might have run if it were not for the time and the grieving of his son who died of brain cancer. this has been slow and steady for joe biden to come around to being supportive of hillary clinton. he has kept his thumb off the scale. i don't think he will much longer. he may be looking for a moment to make this his own moment rather them be part of the news of the day -- rather than be part of the news of the day around president obama and senator sanders. the working-class, white man vote in some circles, at least, in some swaths of the country, most import like, potentially, in the rust belt, pennsylvania, and ohio. we talk about the power of two of the biggest fundraisers in the history of fundraising, bernie sanders and barack obama, now about to help fund raise for her. get are going to try to donors together this month and really start raising money to attack trumps weaknesses. tell us about that. jennifer: there have been some calls and early meetings. senator linton has had -- secretary clinton has had a meeting at her house of big funders who can raise more than half $1 million for her. they are going to try to have a shock and on june -- shock and e june. they are looking to raise maybe a billion dollars. the democrats know they have to play this in the traditional way with a field operation that's strong, not just for the top of the ticket, but for senatorial races, gubernatorial races, and so on. that.ising is all part of if they can get barack obama and michelle obama out there fundraising, that can go a long way. n's campaignto has already made it clear that they will mostly have her on the stump and not campaigning. is not ready to endorse his party's standardbearer. we will tell you why, after this. ♪ e john: welcome back. over the past 24 hours or so, three leading republicans, paul ryan, scott walker, and john repudiated their presumptive nominee in the wake of his comments about a judge of mexican heritage. this appears to be yet another new normal. on the spectrum of mild criticism to scathing rebuke, here are just some of the the party'sf candidate from some of the top figures in that party. >> it's different from what i would do. but my personal interaction, i find him very candid. i think there is no justifying those comments. i was very clear about that. i think everyone should disavow comments like that and i am going to ask that he walks it back. this is a long campaign with a long way to go. it's a long way to go to get a campaign we can all be proud of. expect as republicans, and as americans, that if you want to be reviewed -- viewed as a respectable candidate, you don't extol those believes. beliefs. >> this is not a game to me. i can't go for dividing, name-calling, and somebody who doesn't really represent conservative principles. is it enough, or do something have to give? sustainable. it's it could go on through election day. is it sustainable in a context that would allow donald trump to win and republicans to maintain control of the senate and the house? the answer is no. a chancenk there is that if trump remains the nominee and continues being trump, this could become not just the new normal, but a way of life between now and november. mark: at some point soon, leading figures are going to speak out and say this has got to stop. he is going to be our nominee. you have to be supportive of him. you can't make every new cycle about answering questions about him. people like paul ryan and john kasich -- and apparently stood walker -- don't want to stop answering. tell paulis going to ryan and mitch mcconnell to shut up? who are bigger figures in the republican party than that? well, we will see, but top republicans say this isn't sustainable. it's not just that we can't win at the top of the ticket, but it's going to hurt everybody. it's going to be olli rehn publicans answering for donald trump on what he does and says. -- only republicans answering for donald trump on what he says and does. as one person said to me today, how far does he have to go for people to start flipping? leaders in the party continue to talk about him. tohn: one person jus tweeted that susan collins, the senator from maine, has said she may vote for hillary clinton. a lot of people are saying they will not vote for trump, but not many have openly said they would vote for hillary clinton. that's an interesting development. team for donald j trump met in gotham today. it was the first official meeting of a joint fundraising operation and it comes in a time of skepticism that trump will be able to raise his previously stated $1 billion goal for the election. mark, i ask you, in the context of this meeting and everything else that's going on, what is the state of the health of donald trump's fundraising operation as of now? than some healthier of the coverage suggests. the tone at the meeting today was upbeat. a lot of people are engaged. trump is a pretty big draw. but they are so far behind in the mechanics of this. they don't have the help of barack obama and bill clinton that hillary clinton has. he can raisence enough money to potentially be competitive, but they have a long way to go. john: we talked about this yesterday. i do not see a way for donald trump, given where he currently stands in his fundraising efforts, to raise enough money to run a sophisticated, modern presidential campaign. by that i mean to have real ground operations in the battleground states. to do data and targeting and the kind of things presidential campaigns in the 21st century do. trump can dismiss those things, as he does, and say they are not necessary, but i don't think you can win a presidential election without them. mark: somebody pointed out that this is the kind of meeting that in a normal presidential cycle the republican nominee would have had three years ago. other thing is, can trump start raising internet money? can he start raising the low dollar donations that come in cheaply and build a kind of grassroots movement that any candidate would like to have? john: right. media in alled new respects. he is obviously a huge brand and brandternet is a very friendly. on the other hand, he is a multibillionaire -- by his own accounting -- and a lot of people don't like to money to multibillionaire's. next, some of the longshot party rules changes in cleveland and the politics that would have to occur for that. ♪ john: in the past week, donald trump's comments about judge curio have put him on thin ice with those in the conservative party. that delegates next month should change the support if he does not change his behavior. how realistic are those changes how firm and are the efforts? -- and how strong are the efforts question mark -- efforts? delmon, good to see you. -- gentlemen, good to see you. ben, you have been on television saying this cannot happen, won't happen, very unlikely to happen. explain why you are so pessimistic. >> this is not pessimism-ipo ms. -optimism.simism the political will to make history at a convention is much more difficult. me back for one second. forget about the political will. just in terms of the rules and what would be required, you are saying that's not the hard part. couple ofthere are a different ways being floated. to me, the easiest way is to take the rule that says you need a majority of delegates and make on thesuper majority second ballot. simple word change. trump would need two thirds of the ballot, and he can't get that. >> right. your tim, i know you have finger on the pulse of the never trump and now dumped trump movement. is there a political will to the convention question mark >> it is unlikely, but there is increasing interest. to ben's point, the mechanics of this are easy. trump's polling to tank over the next few weeks as hillary clinton unites the democratic party and gets bernie supporters into her fold. i think the will could be there. there are one or two members of the rules committee who have expressed interest. if you are of the view that donald trump is the standard republican nominee in the mold of mitt romney or ronald reagan, then this seems too extreme. but if you are of the view that he is a threat to the party and the republic, why would you not want to make a change that would give every delegate the opportunity to vote their conscience? i think if you did that, trump would still be the nominee. but i think it's the right thing to do for the party and the delegates. mark: i'm going to ask you to engage in a hypothetical. i don't want anyone to get mad. i am just trying to test the system. take this away from donald trump and the things he has done that have created so much controversy. clearly, if the republican nominee killed a person right now, then people on the committee would say well, of course, we have to find a way, even though this person got the majority, we have to find a way the nomination to someone else. >> or if a candidate got indicted? that kind of hypothetical? mark: leaving aside the political environment, what kind of event could actually be committed -- offense could actually be committed by this nominee that could change your judgment about if this is possible. >> i'm not sure there is any. the leadership to be able to organize not only the rules committee at the the 2470 twout delegates themselves. that world doesn't even gather 2472her into the -- delegates themselves. that world doesn't even gather together until the convention starts. you would need someone the leadership would listen to -- and i'm not sure anyone has identified who those people are -- combined with a need at the convention to be able to form a system to get the delegates to do something like that. , withanswer to that is ben is limited by what possible from a mechanical perspective. this is an unprecedented year. donald trump is an unprecedented candidate. ted cruz and his delegates could organize among themselves that have enough power to make this happen. i think donald trump has artie done everything that would need to be done -- already done everything that would need to be done for this to be on the table. pollnk his pol numbers are basically the only reason more people are not talking about this right now. accused you of having a deadly lack of political imagination. is that the case? horizon, butighter maybe not as bright as tim is seeing right now. i have been on the rules committee and worked conventions before. setting up an operation to achieve something historic like that is really difficult. and you do need the leadership at the top. i have not seen that from the reliever to -- from the leadership of the republican national committee or the elected leaders who actually have influence over who the delegates are. ted cruz is the person who could do it, in theory. john: there was the never trump movement. there's met -- mitt romney. put aside the convention. interest in renewed going back to the original people or others and saying we need a new candidate more than ever now to stop trump? tim: i think there is interest. our supern behalf of pac, our effort was always on the nomination. they were never interested in a third-party bid because of the challenges that go along with that. an texas deadline is now issue, having passed. there are major questions of the third-party bid. never say never in this political environment, but it seems unlikely. miller, despite how rude you were to ben ginsberg, it's always great to have you. tim: i love ben ginsberg. john: it's great having you on the set. coming up, the great katie couric is standing by. ♪ mark: as we said, today donald trump met with top gop butlers to discuss fundraising efforts. here to tell us about that meeting and all things trump, our correspondent katie turner, who joins us from outside trump worn awhere she has groove into the ground because she stands there a lot. katie: it's cold. mark: cold in june. i have heard mixed things about the meeting, but one person who is pretty reliable suggested the donors were upbeat. they like to schedule coming together. they liked trump's seeming enthusiasm about raising money. same thingard the from two sources who were inside the meeting who felt donald trump had a pretty warm reception from those donors. certainly, the trump campaign was positive about it. they talked about how they are going to raise the amount of money they need to raise. they also told us how good the chicken was at the four seasons, but with a big smile on his face. they talked about the electoral map and what states they want to put them play. maryland is on it. that's a new state we have not heard. -- reincethis previous said that any money you do not give to trump you are basically giving to hillary clinton. i did give a chance -- get a chance to ask him how he thinks donald trump is doing. he gave me a thumbs up. a big-time money manager who represents normal gop donors, some of them decided this evento because they don't want their names associated with donald at this moment, especially after his comments about the judge. they have a stake in companies and cannot be associated with ofeone who is being accused racism. it's not only morally reprehensible. it's bad for business. john: a lot of people are saying he may be good enough to win a nomination, but not a general. have the obama endorsement. you have the story about trump not paying people he owes money to come including workers who don't have a lot of money. and his responses to tweet. today is a perfect example. on a new york city street. today is a perfect example of how trump does not have a rapid response team in place. tweets are the extent of the rapid response. the rnc came out with some of their own. usually, in this scenario, somebody like romney or hillary clinton now would have a whole team of folks out there trying to spin their version of the message. the usa today article, which is extraordinarily damning -- they reviewed over 60 lawsuits, hundreds of leads, government filings and judgments and found that donald trump has a history and pattern of not paying small businesses that , even aed with him cabinet maker who had his family hisis -- his company and family for three generations and had to go into bankruptcy after donald trump failed to pay him $83,000 for work on a casino. this is pretty damning for somebody who's messages i am for the little guy and for making the country great again by giving folks what they haven't gotten in the last decade or so, which is better paying jobs. so far, there has been no response from the campaign. we have not gotten any spin on this. this is a story that is likely to snowball from here. this is a good example of how the campaign is caught flat-footed when there are negative stories about them. do you have any response to the hillary clinton tweet should delete his twitter account? from: i think the tweets the responders were quite good and on message for the campaign. they have been talking about the e-mail scandal for a long time. this is one of the things they are going to hit her on as long as they can because it paints her as untrustworthy and as someone who has broken the law. certainly on message. donald trump getting on that message as well. this is one of the first examples of cohesiveness between donald trump in the campaign. hillary clinton campaign or the romney campaign, they would be talking about it a lot more. surrogates would be sending e-mails. they would flood the zone on this issue. more seconds. give me a sense, when donald on personal speech enrichment, he talked about attacking the clintons. do we know where and when that is going to happen? katie: we are hearing it's going to happen in new hampshire. it could also happen in washington, d.c., where his golf courses. we have asked the campaign for more details, and all they have told us is to look into the clinton foundation. we have asked specifically, and all they said was you are a big news organization. i am sure you can figure it out. don't forget, if you are watching us in washington, d.c., you can also listen to us at any time live on the radio at 99.1. we will be right back. ♪ john: one last thing before we go. earlier, i mentioned to tweet about susan collins being open to voting for hillary clinton. that story has now posted. to be clear, she goes on to say, "i am not going to say never." bloomberg.com to read about the negative that or we can expect in the general election. coming up, emily chang talks to a legendary venture capitalist on "bloomberg west." until tomorrow, sayonara. ♪ ♪ friday, the 10th of june. this is "trending business". .nd i am rishaad salamat ♪ rishaad: we will be visiting sydney and singapore this hour. ,he yen's continuing rise japan's biggest bank saying 100 to the dollar by the end of the year.
