Public. With Hillary Clintons camp desperate to bring Bernie Sanders supporters into the fold in advance of the convention, the decision was made she had to go. Debbie Wasserman Schultz. Hello, south florida reporter she announced her resignation a day after introducing clinton and her new running mate in miami. In a statement this afternoon, she said, the best way for me to accomplish these goals is to step down as party chair at the end of the convention. A handful of the 20,000 hacked emails showed her aides musing about how to blunt Bernie Sanders momentum earlier this year. In one the dncs chief Financial Officer wrote, for kentucky and west virginia, can we get someone to ask his belief . Does he believe in a god . He had skated on saying he has a jewish heritage. I think i read hes an atheist. Nobody has apologized to me. Reporter sanders has long argued the dnc, which was supposed to be neutral in the primaries, had its thumb on the scale for clinton. Debbie Wasserman Schultz should not be chair of the dnc. I think these emails reiterate that reason why she should not be chair. Reporter scott pelley asked clinton about the controversy in her first joint interview with her running mate tim kaine airing tonight on 60 minutes. Did you know anything about any of that . No, and i didnt know anything about it and i havent read any of those. But i am adamantly opposed to anyone bringing religion into our political process. The constitution says no religious tests, so that is just absolutely wrong and unacceptable. Reporter senator kaine spent his sunday attending church in richmond and with his son nat, a marine who deploys to romania tomorrow. Needed some prayers today. We get some prayers. Reporter clinton selected kaine out of about two dozen contenders and he made it clear in miami yesterday [ speaking spanish ] reporter that he intends to be her biggest advocate. Hillary clinton, she doesnt insult people, she listens to them. What a novel concept, right . Reporter we learned this afternoon former new york mayor michael bloomberg, who considered his own bid for the presidency, will actually endorse clinton here at the dnc on wednesday. And tonight, scott, Bernie Sanders seth the debbie Wasserman Schultz made the right decision by stepping down. He says hes still fully behind Hillary Clinton and in fact intends to deliver a stemwinder here at the convention on night one tomorrow night. Nancy cordes in philadelphia, nancy, thank you. We asked Hillary Clinton about those incriminating party emails. Just hours after she chose Virginia Governor tim kaine, i should say, virginia senator tim kaine as her running mate, they sat down with us for their first interview for tonights 60 minutes. In your view, in the effort in the dnc to favor one candidate or another would have been improper . Again, i dont have any information about this, and so i cant answer specifically. We ran our campaign. We ran hard. We worked to have as many successes as possible. Im very proud that we got more votes than anybody else running, including donald trump. And i am very grateful for the campaign that senator sanders ran, because we ran a Campaign Based on issues, not insults. So i cant speak to what people who were not working for me, who were saying whatever they were saying, i cant speak to that ary can only speak to my campaign. Senator . I was a dnc chair. So during the first obama term. Youre not going to find anybody at the dnc or rnc or any Political Organization who is a complete agnostic who doesnt have an opinion about a conditioned date. Those of us who are in the realm of have opinions about people. But i dont see an effort to put a thumb on the scale to thin one way or the other. I think the vigorous and is proof that these are Public Servants who were in it for the right reason and i think were going to be unified going forward. Madam secretary, did you hear the Republican Convention chanting lock her up . I didnt hear it because i wasnt watching. But i certainly heard about it. Are yes. Did you feel threatened by that . No, i felt sad. I felt very sad. Sad . I mean, i dont know what their convention was about, other than criticizing me. I seem to be the only unifying theme that they had. There was no positive agenda. It was a very dark, divisive campaign. And the people who were speaking were painting a picture of our country that i did not recognize. Negative, scapegetting, fear, bigotry, smears. I just was so saddened by it. President obama is down to his last six months in office and he talked about the race with John Dickerson on todays face the nation. In 2008, a lot of your supporters said, look at the way he ran his campaign, if he runs the presidency like his campaign, hes going to be in good shape. Why isnt that true for trump . Whos run a pretty remarkable campaign, beating 16 other politicians . In 2008 i dont think they were referring merely to the fact that i had won. We were really well organized. We had a great culture that there was no whiff of scandal to how we approached getting elected. We told the truth. I do think that the body of work of a person matters. And i would say that i genuinely believe theres never been a candidate better prepared for the presidency than Hillary Clinton. Not eisenhower, not George Herbert walker bush . Those are pretty i said more prepared. I didnt say that they were chopped liver. But the skill sets that hillary has are similar to many of the skill sets that they had. She knows her stuff. And more than anything, that is what is ultimately required to do a good job in this office. President obama with John Dickerson. And well be right back from philadelphia. ,,,,,,, dont expect Republican Donald Trump to keep quiet during the Democratic Convention. Hes already talking to cbs news and heres major garrett. Reporter with donald trump and allies counterprogramming the Democratic Convention, ted koppel of cbs sunday morning asked trump what he was thinking when he began this campaign. I have a sense that back on june 16th when donald trump was thinking was, you know something . I might win a primary or two, i might win a caucus or two, but the worst thing thats going to happen is the brand is going to be improved, ill be better known, ill be more famous than i am today, business is going to be you never thought youd be sitting here on this day as the nominee of the Republican Party. I think about it myself, i mean, i think i must have, ted. Because i do like to win. And i believe that if i didnt think i was going to win, i wouldnt have done it. So somewhere deep down in the mind i must have said, im going to win. Reporter trump won the nomination and remains competitive with Hillary Clinton, despite skeletal Campaign Staff and uneven Gop Convention and Prominent Party holdouts. What about the elders, the party elders, who didnt show up . The romneys, the bushes, the kasichs . Look, theyre all people i beat for the most part. I helped mitt romney but i think i talked him out of running in this race. He lost a race he should have won. He should have easily beaten a very, very badly damaged president. And i was very critical of him. Thats why he came out against me. Jeb bush, obviously i beat him very badly. Kasich, i beat him very, very badly. Kasich was beaten so badly. And its hard for people to recover. Reporter trump denied the Gop Convention exaggerated the threat of crime at home or terrorism abroad. I thought it was very optimistic. To me it was an optimistic speem. What makes it optimistic . Because were going to solve the problems. Reporter trump also denied he views the presidency as an allpowerful tool of government action, though his acceptance speech indicated otherwise. Scott, trump and those close to him refuse to comment on the rampant speculation that recently deposed fox news chairman roger as will become a trump adviser or take over the campaign entirely. Major garrett on our philadelphia political team, thank you. With the convention in town, the population of philadelphia is growing by at least 50,000. The citys police force of more than 6,000 officers says its ready for anything. Heres our Homeland Security correspondent jeff. We want a revolution reporter thousands marched in downtown philadelphia this afternoon. They were noisy but peaceful. In 2000, at the last Political Convention here, there were hundreds of arrests. Police say they are prepared if demonstrations get out of hand this week. 35,000 to 50,000 protesters are expected each day. The city has purchased over 250 million in insurance to cover potential damage and another 5 million in case any of the citys Police Officers of sued. The designated protest zone is four miles from downtown within view of the convention site. Former Philadelphia Police commissioner Charles Ramsey says its the unexpected that keeps commanders up at night. Somethings going to happen thats going to be unexpected. And how well are you going to be able to handle that . How flexible will you be . Reporter in this command center at an undisclosed location, the secret service will monitor whats happening. Special agent in charge james henry. We prepare for a variety of different scenarios. Many, many different types of threats. Anything from a lone gunman, an organized attack, an aircraft that comes into restrictioned air space. Reporter weve learned that within the last two weeks the s. W. A. T. Teams as well as the countersniper teams have put their Tactical Response plan to the test and they went through several different scenarios, including an attack on a facility, as well as an ambush of a motorcade. Scott, one more concern, independent lone wolf attacks. Jeff begay covering it, thank you. Another member of the team is anthony salvanto, director of elections. Youve been looking at our polls in battleground states and i wonder did Trumps Convention change the dynamics of the race . He got a small uptick in support. Maybe 2 points across the key swing states. That edges him just ahead of Hillary Clinton. Her support held steady. But whats really telling is where this change came from. Trump drew in a few conservatives who had been undecided before the convention, but virtually no one switched his or her votes from clinton to trump. And that illustrates not just how tight this race is but also how partisan it is. Doesnt look like a Big Convention bounce. What did the voters tell you that they felt as they watched trumps speech on thursday . Republicans saw this very differently from everyone else, scott. They called trumps speech hopeful. They said they felt enthusiastic. But independents and democrats were more likely to call it pessimistic. Democrats said it made them feel scared. So trump rallied his data but t rallied his base. Are democrats happy with tim kaine . There are indications hes seed, but kaine is largely unknown. That sets up this week as a key chance for him to introduce himself democrats. We asked about on the record possible picks clinton might have made, like elizabeth warren. Her name was met with much more enthusiasm, particularly among Bernie Sanders voters. So it looks like Hillary Clinton still has some work to do satisfying those progressive voters if shes going to unify the party at this convention. Anthony salvanto, director of elections, thank you. Cbs news primetime Convention Coverage begins at 10 00 a. M. Eastern time, 9 00 central, 7 00 in the west.

What forecasters call a heat dome is smothering much of the nation and heres maria villarreal. Reporter fire crews struggled to stop the fastmoving sand fire from gutting over a dozen homes. For three days more than 1,600 firefighters have been battling the blaze in temperatures as high as 110 degrees. That fire came through like a freight train. Reporter l. A. County fire chief john tripp. All the experiences weve seen with fire, thats all out the window. Youve got to look at the four major fires weve had in this county in six weeks. We have seen fires explode all over this county. So that ready, set, go program, its not words, its real. Fire was right here. Gigantic flames. Houses were circled completely. Reporter steve arlen and derek hunt own 650 acres in the affected area. Flames destroyed several structures used in dozens of hollywood films and tv shows like the gambler and nightrider. At some point you know youre defeated and you have to step back. We fought as best we could. Helicopters were dropping, water, everybody was out there doing their best to save it. Reporter like california, much of the nation is dealing with overwhelming heat. From chicago to philadelphia, a sweltering heat wave has temperatures lingering well over 100 degrees. Today Race Organizers in new york altered their course because of the extreme heat. Triathletes found the fastest way to find relief was in the hudson river. Temperatures here in california are a bit cooler than they have been in the last few days. Homeowners were expected to come back home, but an unexpected shift in the wind has picked up the flames you see behind me. That is forcing a lot of officials to make sure those evacuation orders stay in place. Maria villarreal, thanks. Next, were others involved in the mass shooting in munich .

He killed nine before taking his own life. Seth doane has been looking into why. Reporter german plers say david alisome bolly had been preparing his attack for more than a year. The 18yearold was bullied at school, suffered from depression, and spent two months in a psychiatric hospital. He apparently shot his nine victims at random. Investigator Robert Heimburger told us at this point they have not established a clear motive. You say he was obsessed with mass killings. Was there a turning point when you realized that indeed he was planning one himself . We cannot say if there is an exact point in time, he said. But in 2015 he started conducting research on mass killings. Some bolly visited the site of a 2009 mass shooting where another teenage gunman killed 15 people. Police say he was an avid fan of violent video games. But in real life, he seemed timid. The boy lived just across the street . Yes. Reporter hawken runs a hair salon near where the gunman lived with his family. He was shy, even when i was cutting his hair he wouldnt talk much. He wasnt weird, he was just quiet. The teen purchased his glock handgun illegally online and fired 57 shots, including the one to his head, which killed him. The teenage killer wrote a manifesto that was so long the police have not yet been able to analyze it. It appears he was not motivated by any ideology. Scott, the police told us, simply he was a young, mentally ill man. Seth doane reporting, thank you. Next from philadelphia, will the russians compete in rio . Russia caught a break today when the International Olympic committee stopped short of banning all russian athletes from the rio olympics because of widespread doping. Instead, the organizations that run each sport will make the decision on who can compete. Russias track and field team was previously banned and that remains in effect. Baseballs hall of fame inducted two heavy hitters today. Ken griffey jr. Played 22 seasons with the mariners, reds, and white sox. He hit 630 home runs. That was good for sixth place alltime. Mike piazza hit a record 396 homers as a catcher. Not bad considering that he was picked by the dodgers in the 62nd round of the 1988 draft. Political insight from,,, joining us in philadelphia, one of the Founding Fathers of television Convention Coverage, bob schaffer. Bob, what does Hillary Clinton have to do here .
