Saying, this is war. The outrage in baltimore tonight, all charges dropped. The remains officers will not stand trial in the freddie gray case. And the urgent search. The family that went missing while snorkeling. And late word now coming in. Good evening from philadelphia tonight, where there are two major headlines breaking as we come on the air. Just as the Democratic Convention plays out here in ph philly, it was donald trump today who walked in front of the cameras and ignited a firestorm with what he said. Inviting russia to spy on Hillary Clinton. It all comes as you look live tonight at the convention hall. This crowd, awaiting president obama a short time from now. And youll remember, it was eight years ago, Hillary Clinton who lost to him, came out at that convention and said barack obama was her candidate. Tonight, he will do that for her, in fact, we have just learned some of what the president plans to do on this stage behind me. But it was what donald trump said today that caused an uproar. Did he encourage espionage . Abcs tom llamas, leading us off. Reporter tonight, donald trump with a message to russia hack Hillary Clintons emails from her time as secretary of state, and release them publicly. Russia, if youre listening, i hope youre able to find the 30,000 emails that are missing. I think you will probably be rewarded mightily by our press. Reporter and trump, not backing away from encouraging the cyber espionage. Do you have qualms about asking a foreign government, russia, china, anybody to interfere, to hack into a system of anybodys in this country . Thats up to the president. Let the president talk to him. Does that not give you pause . No. It gives me no pause. If they have them, they have them. Hey, you know what gives me more pause . That a person in our government, crooked Hillary Clinton, heres what gives me pause. Be quiet. I know you want to, you know, save her. Reporter the bipartisan backlash, fast and furious. Clintons top Foreign Policy adviser calling this a National Security issue, adding, this has to be the first time that a major president ial candidate has actively encouraged a foreign power to conduct espionage against his political opponent. And from a spokesman for House Speaker paul ryan, russia is a global menace led by a devious thug. Putin should stay out of this election. Trump seeing it a different way. Im not going to tell putin what to do. Why should i tell putin what to do . Reporter the republican nominee has showered praise on the russian president. Look, hey, putin likes me. I think id get along with him. I respect putin, hes a strong leader. Reporter but today, trump denies any relationship. I never met putin. I dont know who putin is. He said one nice thing about me. He said im a genius. I said thank you very much and that was the end of it. Reporter still, trump has courted russian billionaires close to putin to invest in his projects. One of them hosted trumps Miss Universe pageant in moscow three years ago. Now, growing questions about whether trump has business deals in russia, and whether the proof lies in his tax returns, which he is refusing to release. Do you have any Major Investments in russia . None. Reporter and if the answer is no, why not release your tax returns . Because its under audit. Ill release them when the audit is completed. But zero, i will tell you right now. Reporter and for good measure, trump blasting president obamas frosty relations with putin. Putin has said things over the last year that are really bad things, okay . He mentioned the n word one time. I was shocked to hear him mention the n word, you know what the n word is, right . I was shocked. He has a total lack of respect for president obama. I think hes going to respect your president if im elected. And i hope he likes me. And tom llamas is live tonight from scranton, pennsylvania. Tom, we heard donald trump tell you there that he wont release his taxes until the audit is complete, which could be after election day. But you told us there were two other moments during that press conference where reporters corrected him . Reporter thats right, david. In that press conference that lasted almost an hour, donald trump made two noticeable mistakes. First, he called the reagan shooter david hinckley, not john, and then, he criticized tim kaine for doing a bad job in new jersey, when he really meant virginia. Both times, reporters corrected him, almost instantly. David . Tom llamas, leading us off tonight. Tom, thank you. Meantime, this evening, we have just learned some of what president obama plans to say about Hillary Clinton, just a short time from now. And Abcs Cecilia Vega is right down on the floor with that part of the story tonight. Reporter tonight, president obama preparing to take the stage for what the white house calls, quote, the biggest moment he has left. Whats happening tonight . Oh. That was a joke. You look so serious. Feel great. Reporter obama arrives in philadelphia with one urgent goal. To make the case for Hillary Clinton. It is his turn to return the favor. In 2008, clinton in defeat, on that convention stage, urging her supporters to vote for him. Barack obama is my candidate and he must be our president. Reporter from bitter adversaries on the campaign trail to close partners in the white house. Now, the president , her most powerful ally. There has never been any man or woman more qualified for this office than Hillary Clinton. Ever. Reporter senior white house officials telling abc news the president will make clear tonight that she is, quote, the torchbearer for the Democratic Party. And yes, expect some hard knocks on donald trump. And he is already decrying the attacks on clinton. As somebody who has had my share of getting whacked in the public eye, im surprised by it sometimes. And i dont think it is fair. Reporter obama, of course, not the only president in clintons corner. In the spring of 1971, i met a girl. Reporter bill clinton lashing out at her republican opponents. A real change maker represents a real threat. So, your only option your only option is to create a cartoon. A cartoon alternative. Then run against the cartoon. Reporter tonight, Hillary Clinton herself one step closer to celebrating this historic moment. And cecilia vega joining us down from an excited crowd there on the floor tonight. And cecilia, bill clinton last night never mentioned donald trump by name, nor did Michelle Obama on night number one. But youve learned tonight that president obama will this evening . Reporter david, were told that unlike those other speakers, the president will go there, and he will mention Donald Trumps name repeatedly. Once source just now telling me that when it comes to donald trump, the president will lay out whats at stake in this election. David . All right, cecilia, ill see you in primetime tonight. In the meantime, we do have new reporting this evening on when president obama spent much of his time finishing what he will say about hnl hillary clin right here tonight. It has a lot to do with what he saw from his wife, first lady Michelle Obama, earlier this week, who started the week off. Abcs Jonathan Karl is on the floor tonight, and you have learned, he was up watching and then stayed up for hours after the first ladys speech to finish this off . Reporter david, the president started writing his speech more than two weeks ago. He had been through it about a half dozen drafts, at the white house on monday night, he was watching Michelle Obama give her speech, and after that, he stayed up until 3 30 in the morning, we are told, at the white house, reworking his speech. Obama alumni on the clinton team are not lowering expectations. They are expecting one of his best speeches. And we heard cecilia just record that the president is expected to talk about donald trump here. But you have right in front of you some of that speech. One of the central arguments the president plans to make tonight . Reporter hell talk about his time working side by side in the white house at Hillary Clinton, including during that raid. Nothing truly prepares you for the oval office. Hillary has been in the room. Shes been part of those decisions. All right, jon karl, thank you. As you know, also on that stage this evening, virginia senator tim kaine. Hillary clintons choice for v. P. He was on that stage for a walkthrough today, tweeting this photo with the caption taking it all in. But what about the other potential v. P. Picks passed over, among them, senator elizabeth warren. Asked her tonight, does she believe kaine was the right pick . But i start with donald trump, who tweeted after warrens speech here in philly, sad to watch. And he used a name he frequently calls her. After your speech, donald trump sent out a tweet, calling you pocahontas im shocked. Reporter is that racist . You know, donald trump has proven that he is a thinskinned racist. Reporter but is that calling him a name, too. No, it fits the fact. Come on. Look at what he has said about mexicans. Look what he has said about muslims. Look what he says over and over. In fact, you dont even have to quote me on this, when he had rulings against him over trump university, he was being sued for fraud over that university, he tried to attack the judge. Donald trump said, well, i think ive heard that he is mexican and therefore, he cant sit in judgment in my case. Reporter the Democratic Party has embraced you. In particular, you are a darling on the left, and so many people wanted you to be the v. P. Pick. When tim kaine became the pick, and a lot of people in this crowd when they heard Clinton Kaine booed at the beginning of this week. Was he the right pick . Look, ive known tim kaine since ive been in the senate and he is a good man. Reporter but the right pick . Well, hes a good man, he has a good heart and he has a lot of experiences. I think hes going to be a valuable member of the team for secretary clinton. Reporter there are so many people in this country who look at Hillary Clinton, shes been in the public eye for 25 years in this country, and yet they feel like they still dont know her, they dont know what makes heretic. What does she need to do on that stage . Thats a good question. You know, shes had 25 years of attacks. And in a sense, for me at least, i think that means shes really revealed to the American People who she is. A lot of people wouldve just hung up their spurs. They would have said, you know, take it, i dont need this. But instead, she gets up and fights for what she believes in. Senator warren, oneonone with us. And ill be joining george and the entire Powerhouse Political Team later tonight in primetime, 10 00 eastern, for full coverage of president obamas speech and, of course, well see you then.
