6:00. tonight, the breaking news here. word of a major resignation just hours before the democratic convention. the new party turmoil. the chair of the dnc, now saying she's out tonight amid leaked e-mails. did the dnc favor hillary clinton all along? was bernie sanders right? and hillary clinton tonight, side by side with her new running mate. this evening, he's coming to her defense amid the name-calling from donald trump. and you'll hear it. the other breaking headline. the sweltering heat and fires turning deadly. evacuations under way right now. dangerous heat alerts from kansas all the way to philadelphia and new york. as the death toll rises, including a 12-year-old who was hiking. dramatic video of a plane spiraling, crashing into a home. witnesses running in to help. the deadly machete attack, taking aim at a pregnant woman, among others.

the images coming in from the scene. and the security breach at a major american airport. a man with no ticket breezing by the tsa, boarding the plane. good evening. from philadelphia tonight, where the democratic national convention hasn't even started, and we already have our first major controversy. the chair of the dnc, congresswoman debbie wasserman schultz, has resigned due to leaked e-mails. bernie sanders supporters say the e-mails prove the party favored hillary clinton all along. sanders reacting to the e-mails, but making it clear he will be here to support hillary clinton. meantime tonight, the democratic ticket now revealed. clinton/kaine. we have new reporting on what into hillary clinton's choice. tonight, senator tim kaine

sitting right next to hillary clinton, coming to her defense when asked about the name calling by donald trump. and cecilia vega, you're here with me. the new democratic ticket being announced, but the headlines are about the dnc e-mails and bernie sanders. >> reporter: not what huk -- hillary clinton wants heading into this week. this is supposed to be about party unity. instead, this is the exact opposite. on the eve of the democratic convention, tonight, a bombshell. party chairwoman debbie wasserman shultz resigning after wikileaks released thousands of internal democratic national committee e-mails suggesting the party favored clinton over bernie sanders. an 11th-hour effort to blunt the controversy hanging over clinton's convention, and upstaging the announcement of her running mate, virginia senator tim kaine. >> senator tim kaine is everything donald trump and mike pence are not. >> reporter: fresh off their big debut, clinton's words of encouragement picked up by the

microphones. >> go get them! >> this is great. all right. >> reporter: unlike donald trump, who spoke for 28 minutes before introducing his running mate -- >> back to mike pence. >> reporter: -- then walking offstage. clinton made kaine the star of her show. he spoke 38 minutes to her 17. >> hillary clinton, she doesn't insult people. she listens to them. what a novel concept, right? >> reporter: now, their first joint interview, with kaine's new role as trump attack dog on full display. clinton asked what she calls trump, since he calls her crooked hillary. >> i don't call him anything. and i'm not going to engage in that kind of insult fest that he seems to thrive on. >> i don't want to -- she's done a good job of letting the, you know, water go off her back on this. that's not the way i feel. when i see this, you know, crooked hillary, or i see the "lock her up," it's just ridiculous.

and look, most of us stopped the name-calling thing about fifth grade. >> reporter: they may be presenting a united front, but now it's democratic unity that's under threat. those hacked dnc e-mails enraging sanders supporters. in one e-mail, a top dnc staffer wonders about sanders -- "does he believe in a god. he had skated on saying he has a jewish heritage. i think i read he is an atheist. this could make several points' difference." sanders called for wasserman schultz to step down. but he didn't back away from his support of clinton. >> we have got to defeat trump. we have to elect hillary clinton. >> bernie sanders says he'll be here to help hillary clinton. cecilia vega back with us now. you've been working your sources on the tim kaine choice. who are they hoping he appeals to, is able to help her with? >> reporter: this is about winning white, male, and independent voters. and also about giving hillary clinton a boost in the all-important swing state of virginia. and i'm told this also came down to chemistry, you saw them on the stage, they certainly have

that. >> cecilia, thank you. the hacked dnc e-mails revealing what democratic party leaders were saying about bernie sanders. tonight, the clinton camp with an eye-opening theory about who's behind the leak. the clinton campaign manager saying it's the russians trying to help donald trump. jonathan karl, did he really say that? >> he did. this is a huge allegation, david. this would make the watergate scandal look minor by comparison. here's what we know. about a month ago, the dnc computers were hacked by computers believed to be based in russia. but the clinton campaign presented no evidence that the computers were tied to the russian government. or that there was any collusion whatsoever with the trump campaign. they attribute it to experts. >> do we know if there was any pressure from the clinton camp for congressman wasserman schultz to resign? to sort of make sure we were talking about this on sunday night, and not monday, tuesday, wednesday, during the convention? >> make no mistake, she was pushed out.

the clinton campaign wanted to be done, turn the page. it also took a call from president obama to finally get her going. she is going to gavel in the convention, she is going to be here, and i'm sure the bernie sanders supporters will be booing her quite loudly. >> but a much smaller role. thank you, jon. in the meantime, the trump campaign already reacting, saying hillary clinton should drop out of the race, follow wasserman schultz's lead, due to clinton's own e-mail scandal. but donald trump himself is also responding to something else tonight. to those who say his convention speech was too dark. and four days after ted cruz was booed off the stage, trump is still talking about cruz. tom llamas on the campaign trail tonight. >> reporter: tonight, on the eve of the democratic convention, donald trump still bragging about his own big speech. tweeting out this video with an applause-o-meter, claiming 24 minutes of pure cheering.

>> the only thing that some people said, it was a little dark. it was a little bit tough. >> did you think it was a little dark? >> no, i thought it was very optimistic. to me, it was an optimistic speech. >> reporter: but at times trump did paint a grim picture. >> our convention occurs at a moment of crisis for our nation. illegal immigrants with criminal records, ordered deported from our country, are tonight roaming free to threaten peaceful citizens. the attacks on our police, and the terrorism of our cities, threaten our very way of life. >> reporter: trump now also refusing to end his feud with senator ted cruz. >> stand and speak and vote your conscience. vote for candidates up and down the ticket. >> reporter: it's been four days since cruz was booed off the stage after refusing to endorse trump, as the billionaire watched from the crowd. >> i did him a favor because had i not walked into the arena at that moment, i think they would

have ripped him off the stage. >> reporter: but trump's good will ends there. he's now promising to fund a super p.a.c. to take out cruz and ohio governor john kasich, who boycotted his convention. >> yeah, i'll probably do a super p.a.c., you know, when they run, against kasich. >> okay. >> for $10 to $20 million. against ted cruz. and maybe one other person that i'm thinking about. >> reporter: it's unclear which politician trump was speaking about right there. trump will be busy this week. he's on the move, hitting several battleground states, including north carolina, florida, and ohio. david? >> tom, thank you. we will have full coverage of the democratic convention in philadelphia all week long.
