Plus, why paul ryan finally came around to trump today. Why new polling in california could have big implications for democrats. And as new details continue to emerge, why donald trump says he wants to reopen Trump University. Success. Its going to happen to you. When all in starts now. Good evening from new york. Im Steve Kornacki in for chris hayes tonight. And today Hillary Clinton delivered perhaps her most stinging attack yet on donald trump. Speaking in san diego, the former secretary of state flanked by 19 american flags laid out her Foreign Policy vision while seeking to portray the republicans presumptive nominee as unstable, inexperienced, and fundamentally unfit for office. Donald trumps ideas arent just different. They are dangerously incoherent. Theyre not even really ideas. Just a series of bizarre rants, personal feuds, and outright lies. This is not someone who should ever have the nuclear codes. Because its not hard to imagine donald trump leading us into a war just because somebody got under his very thin skin. Clinton came back again and again to trumps temperament. She also laid out a brutal critique on trumps opposition to the Iran Nuclear Agreement and his tweets. Donald trump doesnt know the first thing about iran or its nuclear program. Ask him. It will become very clear very quickly. [ cheers and applause ] you know, theres no risk of people losing their lives if you blow up a golf course deal. But it doesnt work like that in world affairs. So the stakes in global statecraft are infinitely higher and more complex than in the world of luxury hotels. We all know the tools donald trump brings to the ble. Bragging. Mocking. Composing nasty tweets. Im willing to bet hes writing a few right now. And in fact donald trump was. Just minutes before clinton made that comment, trump tweeted, bad performance by crooked Hillary Clinton. Reading poorly from the teleprompter. She doesnt even look president ial. Trumps tweet during clintons speech stopped there. But the former secretary of state wasnt done. Leveling another critique at trumps fitness to be commander in chief. So it really matters that donald trump says things that go against our deepestheld values. It matters when he says hell order our military to murder the families of suspected terrorists. During the raid to kill bin laden, when every second counted, our s. E. A. L. S took the time to move the women and children in the compound to safety. Donald trump may not get it, but thats what honor looks like. Trump was speaking to the New York Times during clintons speech. Heres what he said about it. He called it terrible and pathetic. He added, im not thinskinned at all, im the opposite of thinskinned. Earlier in the day he tweeted, crooked Hillary Clinton, who i would love to call lying hillary, is getting ready to totally miskept my Foreign Policy positions. And trumps tweets to get ahead of clintons speech were a continuation of his efforts last night when speaking to a crowd in sacramento. He claimed clinton was lying about his views. Remember this. Hillary clinton and this is 100 Hillary Clinton, who lies, i mean, she lies, you remember that, i started that. She lies. She lies. She made a speech. And shes making another one tomorrow. And they sent me a copy of the speech. And it was such lies about my Foreign Policy. That they said i want japan to nuke, i want japan to get Nuclear Weapons, give me a break. Trump was right clinton was going to bring up his position on japan and Nuclear Weapons and contrary to what trump said there, it isnt a lie. In fact, he has said that japan should pursue acquiring Nuclear Weapons. He said that just over two months ago in an interview with cnn. Today Hillary Clinton gave us a preview of what her general Election Strategy against trump could look like. A lot of sarcasm, humor, all while trying to make the case that donald trump is dangerous for the country. The question is, will that work . Joining me now is Karen Phinney, Senior Strategic Communications adviser and spokesperson for the Clinton Campaign. Karen, thanks for being here. Great to be here. Weve had a number of highprofile speeches from major politicians the last year. I think of mitt romney, former president george w. Bush, others who have tried to make the case that donald trump is basically discredited from serving as president. What would make this one different today . Well, i think youre seeing Hillary Clinton do something that 15 men werent able to, do make the case against donald trump in a very effective way. She used a little bit of humor, a little bit of heart, talking about our values as a country. But also talking about the dangerous and divisive consequences of the kinds of things that donald trump says. As you pointed out, talking about countries like japan getting Nuclear Weapons or saudi arabia getting Nuclear Weapons. Or suggesting that he knows better than our generals about isis. Those kinds of comments are dangerous, theyre divisive, and they would have real consequences. Imagine, he just decides to get into a spat with David Cameron, just because. On twitter. What if he were president . And then he had to go to David Cameron and try to forge an alliance around a problem that needed to be solved. How do you do that when youve been insulting people . Think about particularly with regard to insulting muslims and immigrants as hillary pointed out. How do you then go to muslim nations and try to say, we need to build an alliance . You lose credibility. I think there is a real reason that so many World Leaders have come to president obama and others and expressed their real concern about donald trump and his temperament, and as she said, do we really want this guy to have his finger on the codes . There was, as we say, the topic was National Security today. There was heavy on sarcasm, attempts at humor in this. She tried to make this point by point her view. This point, this point, this point, why hes unqualified on this topic. This is a template that we saw today . Are we going to see more speeches like this on other topics . I think what youre going to see, a cull of things. Number one what hillary did today was lay out the choice for people in terms of the vision that donald trump is pushing, which is divisive. It would be dangerous. It would be noninclusive which i think is internally dangerous in our country. And also frankly i agree with her, im tired of donald trump crapping on our country. Hes been doing ate long time. How can you do that and then credibly say youre going to be able to be president . Versus what hillarys talking about which is a positive vision, its an optimistic vision, its an inclusive vision, but its about not just security in terms of our National Security, but how do we grow our economy . Shes not talking about like get rich quick schemes like Trump University. How do we really a critic of this speech today would say, this was heavy on criticism of donald trump, this was really strongly delivered, there was a lot in here that will get peoples attention. There wasnt a lot in here about her vision on Foreign Policy. There wasnt a lot in here on her record on Foreign Policy. Heres why i disagree with you on that a bit. She has been talking about both her record and what she wants to do for the last year. So for example, when she was talking about the contrast between the two of them, when were talking about how are you going to take down terrorist networks, first of all, obviously if you think you know more than the generals and youre not even willing to listen to people who might have other information, thats not a good strategy and thats actually very dangerous. But shes also laid out a full plan that talks about, how do we deal with terrorist networks in cyberspace . How do we deal with that and the reality theyre using cyberspace andechnogy to recruit people outside of the boundaries of the countries were talking about, as well as how do we deal with what were seeing in the middle east . We have not heard anything like that from trump. Let me ask you this. We have that clip in there where she talks about hes running the golf courses. Trying to say basically, this guys got no business setting Foreign Policy for this country. She was secretary of state. Shes trying to set up a contrast. Four years as secretary of state. Tell me, what is the signature achievement, four years as secretary of state, what is the one most important achievement she made . I would say the one most important achievement she made, because it flows to others, is the fact that she got on the plane and helped rebuild our alliances that were very badly damaged. It was those alliances that needed to be rebuilt so that we could be in a position for her to take on china and get them to take part in the iran sanctions, which led to the Nuclear Agreement with iran. It was because of rebuilding those alliances that we were able to get the paris accords on Climate Change done. It was because of those alliances that weve actually restored and renewed americas standing in the world. And now again i think the choice that she is making is, we can go forward as a strong america, as a proud america, or we can let this divisive view that donald trump is pushing be the direction that we go. And i think what you will see certainly is making the case that its not just sure its a little funny here and there. But its actually dangerous. When you really kind of go through, take through the thread of what hes saying to its consequence, then its really dangerous. And i think that also makes it very real for the american people. Karen phinney from the Clinton Campaign, thanks for the time. A. J. Delgado, conservative columnist and trump supporter. A. J. , you saw the speech, youve heard Karen Phinney from the Clinton Campaign. Did clinton draw blood today . Not at all. I think she exposed herself. You alluded to her earlier in the segment when you asked, really there was no substance to her speech. I dont know if anybody else found this as bizarre and frightening as i did that a president ial candidate gave this speech that was really just an attack on her opponent and had almost nothing as to what her view and her policy positions are. When donald trump gave his speech a month or two ago on Foreign Policy, it was on what his vision is what his policy views are on Foreign Policy, and his ideas. Hillary clintons almost entire speech today was just why Donald Trumps ideas are wrong, but nothing about her own, it was bizarre. What about that . Youre a supporter of donald trump and she did make the case here for why she thinks donald trump is wrong on National Security, wrong on Foreign Policy. Lets go through specifics. When i ask if she drew blood, im curious. She talks about his use of twitter, about how he seems erratic in terms of going on there, picking fights with people, saying incredibly inflammatory things, asking the american people, is somebody like that temperamentally suited to have their hand on the Nuclear Trigger . What would you say . The American Public appreciates how much he uses twitter and is candid and direct with us. Hillary clinton is somebody who hides out and literally, i dont use that term lightly, been in hiding most of her campaign. She has not had a press conference in what is it, six months . I think the American Public has spoken and saying, wed rather somebody who is open and candid and maybe a little rough around the edges sometimes on twitter, but at least he speaks to the American Public. Also in terms of the positions he takes when he speaks, the things he articulates, she said another part of this indictment of his Foreign Policy saying its incoherent. Isnt there something to that when he goes around saying he was against the iraq war from the beginning, and actually before the iraq war he said we should invade . No, actually, that has been completely misinterpreted and micerepresented in the media. Donald trump from the very beginning was against the iraq war. Two months before the iraq war, in january 2003, he gave an interview with neil kabuto on fox news where he expressed heavy skepticism, saying we should focus on the economy and not go to war i want to read something from 2002 you just said that he lied about opposing it and he didnt, hes been against the iraq war i want to put this on the record, a. J. 2002, before the invasion. He was on the howard stern show. Heres the direct quote. Howard stern i know exactly what youre talking about. Hang on. Howard stern says, are you for invading iraq in the answer is, yeah, i guess so. That doesnt sound like somebody whos against this. A rousing endorsement . Yeah, i guess so . I didnt say rousing, i said endorsement. He didnt say no, he said yeah. That was 2002. And sofy may respond now in 2003, march is when we entered the war. January 2003, two months before the war when is he gave that nile babuto interview. Anybody could look that up. But youre talking about an interview where he raised some concerns about maybe this wasnt the wisest thing. When Hillary Clinton says incoherent, if you have a guy who says in one interview, yes, we should go in, another one who expresses some reservations about it, and now says i was against it from the beginning and i tried to warn the country. Isnt that the definition of incoherent . All of that is actually, no, quite on the contrary. It sounds completely consistent. Five days after the war he called it a mess at a vanity fair party, look that up as well. What i find much more worrisome than his alleged inconsistency is hillarys. This is somebody who did flatout support and lead us and make us go into iraq. And was supportive of it for years. Does that not worry you more than whether trump said i guess so in 2002 . The fact that Hillary Clinton led us into that disastrous war and supported it for as many years as she did in the fact that she led us into libya, the fact that she wants us to intervene in syria, wants us to have conflict with russia . Is that not the worrisome angle here . Not whether trump may or may not have been truck enough in his denial that the war was a good idea . Again, enthusiasm wasnt the question. In 2002, yes no answer, and he said yes. A. J. Delgado, supporter of donald trump, i appreciate the time. More fallout from the clinton stop trump speech today. Plus new reporting on the Trump University scandal. As donald trump suggests he wants to reopen that school. House Speaker Paul Ryan falls into line. His endorsement of donald trump in two minutes. Seriously, its, its really fine. You dont want to be seen with your dad . No, its. No. This about a boy . Dad stop, please. Oh, theres tracy. What [ horn honking ] [ forward collision warning ] [ car braking ] bye dad it brakes when you dont. Forward collision warning and autonomous emergency braking. Available on the redesigned passat.

Man 2 the world has changed. Man 1 meaning . Man 2 its not just security. Its defense. Its not just security. Its defense. Bae systems. Todays speech from Hillary Clinton warning about what she says are the dangers of donald trump as president , not the first of his kind, but will she succeed where mitt romney, marco rubio, and rick perry failed before her . Thats next. But first, 29 days after donald trump was declared the presumptive nominee of the Republican Party, he has now finally won the support of house Speaker Paul Ryan. While ryan maintained for weeks he was just not ready to endorse trump, this afternoon he published an op ed piece that declares donald trump can help make reality of the bold house policy agenda. He spoke shortly after with the Associated Press. I didnt know the guy at all before he got the nomination. Quite frankly i didnt expect the nomination to be clinched until june 7th at the earliest. So i never had the time to put the time into talking with donald about just the country, about principles and policies. Its very clear to me that Hillary Clinton in no certain way going to be advancing our principles and policies. Shes promising another obama term. And its also become clear to me through my conversations that Donald Trumps somebody i know is comfortable with these principles an
