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. In another breaking story tonight, explosive wildfires are burning in the west, including two large fires in california inflamed by tripledigit heat and droughtdried brush. 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 . Well, i think she has to be very careful. Because you know, when donald trump was in cleveland, he really came down hard on terrorism and all that. The people in the hall liked him. But outside the hall, some people were frankly frightened by all of that. And she has to be careful not to totally discount the threat of terrorism. People are worried about terrorism. She cannot discount it entirely just in order to put down him. But the other thing, scott, is the chaos in which this convention is getting under way. I mean, this has been a year of surprises but if you had told me that this convention was going to open in chaos, the Democratic NationalCommittee Chairwoman was going to resign over yet another email scandal, and then the clinton people say theyre hearing from experts this is the fault of russians and the that the russians may have been doing this to help donald trump, i mean, this is above my pay grade. I dont know, i just wouldnt have predicted this. Speaking of trump, he hasnt toned anything down. Hes not only not toned it down, hes ratcheted it up. Today when chuck todd asked him would he support a democrat over former ku klux klan leader david duke, whos going to run for the senate, he said, yes, he would support a democrat, but hed want to know who the democrat was. I mean, ive never heard anybody qualify an answer quite like that. And then yesterday bob, thank you very much. Thats the overnight news for this monday. For some of you, the news continues. For others check back for the morning news and cbs this morning. From the site of the Democratic National convention in philadelphia, im scott pelley. This is the cbs overnight news. Welcome to the overnight news. Im meg oliver. The delegates are gathering in philadelphia for tonights opening of the Democratic National convention. Hillary clinton and her running mate tim kaine will get the formal nomination of the Party Faithful to head the democratic ticket in the november election. Before they travel to philadelphia, the running mate sat down with scott pelley for 60 minutes. Madam secretary, did you hear the Republican Convention chanting lock her up . Lock her up, lock her up well, i didnt hear it because i wasnt watching. But i certainly heard about it, yes. Did you feel threatened by that . No, i felt sad. Sad . I felt very sad, scott. 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. He called you crooked hillary. What do you call him . I dont call him anything. And im not going to engage in that kind of insultfest he seems to thrive on. So whatever he says about me, hes perfectly free to use up his own air time and his own space to do. Im going to talk about what hes done, how he has hurt people in business, time after time after time. His vicious language against immigrants. His insulting a distinguished federal judge of mexican heritage. His mocking a person with a disability. His really inflammatory language about muslims, about american muslims, about muslims all over the world. His demeaning comments about women. Im going to respond to what he has said that i think is so fundamentally at odds with who we are as a nation, where we need to be heading in the future, and the kind of dangerous, risky leadership that hes promising. Can i say this . I dont want to shes done a good job of letting the water go off her back on this. Thats not the way i feel. When i see this crooked hillary or i see the lock her up, its just ridiculous. It is ridiculous. The republican fbi director makes a decision that theres nothing here that warrants any additional activity no criminal prosecution. So theyre going to say, okay, we dont believe him now. You saw all these folks trying to rehash the tragic deaths of americans in libya, which we should all feel for those families, theyre trying to politicize it. Whats your responsibility for benghazi . Did you make any mistakes around that . Well, scott, there have been i think now nine separate investigations, and they did not find any such culpability. I took responsibility, i was secretary of state. And i thought that was appropriate. And what i was determined to do is to find answers as to what actually happened, not what people claim, and what we could do to try to prevent that. That is in the tradition of what has happened in the past. Weve had horrible losses in beirut, when Ronald Reagan was president. One of my favorite former predecess predecessors, george schultz, was secretary of state. We had a democratic congress. They didnt politicize it. So when this happened in benghazi, i immediately stood up an independent committee, distinguished americans, military and civilian experts. They came out and they said, you know, the ball was dropped in security. And some of the decisions that were made probably should have been rethought. But wasnt that your ball to carry . No, it wasnt. It was not my ball to carry. Read the reports. Read all of the reports, alm hundreds of pages of them, including this latest one, which was a political exercise from the very beginning. Those never reached me. Those never came to my attention. The concerns about the security never came to your attention . No, the experts we have security experts. I am not going to substitute my judgment for people who have been in the field, who understand what our men and women are up against. So this has all been investigated over and over again. But as tim was just saying, it didnt get the result that some of the republicans wanted, so they kept at it. And i feel very sorry that they have politicized it unlike any prior example. And i just think the most important challenge we face is learning from it and doing everything we can to keep our people safe. Ive got about three more questions that shouldnt take too long. One of them you might actually like. Then well take one question. Exactly, yes. All right. Do you think you blew it on the emails . Oh, ive said i did, absolutely. I made a mistake. I should have had two accounts, one for personal and one for office. And i didnt. And i take responsibility for that. Why did you do that . Have the private email servers . You know, scott other people did have, other secretaries of state, other highranking members of administrations, plural. And it was recommended that it would be convenient. And i thought it would be. Its turned out to be anything but. Would there be a private email server in the white house . Ill tell you one thing, that is one lesson i have learned the hard way. And there will not be any such thing in the white house. Although i am quick to add theres no evidence that it was ever hacked. And unfortunately, you cant say that for a lot of the government. I was speaking to a young africanamerican man just the other day in a democratic state. And he said, and ill quote, you know, i guess i would vote for hillary, except for that corruption problem. As i talked to him further, he didnt quite know what he meant by that. But that was his impression and concern. Why do you think people say that about you . Well, first, i will take responsibility for any impression or anything ive ever done that people have legitimate questions about. But i think that its fair to say theres been a concerted effort to convince people like that young man of something. Nobodys quite sure what. But of something. I often feel like theres the hillary standard and then theres the standard for everybody else. Well have more of scotts interview with Hillary Clinton and tim kaine tomorrow. And of course cbs news will bring you primetime coverage of the Democratic Convention throughout the week. But in two minutes, John Dickerson wil will sit down with president obama to discuss what it takes to lead the nation. The overnight news will be right back. Introducing new ky touch gel creme.

The delegates will formally nominate Hillary Clinton and tim kaine to lead the party in the november election. The man they hope to replace, president obama, sat down with John Dickerson of face the nation. They discussed life in the white house and life ahead. When donald trump spoke to his convention, he talked about the security threats. He painted a very dark picture. Now theres been a terrorist attack in germany. Doesnt that suggest hes right about the darkness . No, it doesnt. Terrorism is a real threat. And nobody knows that better than me. Ive been spending most of my days over the last seven and a half years coordinating our intelligence, our military, our diplomatic efforts, to crush organizations like al qaeda and now isil. It is going to be an ongoing threat for some time. But what weve been able to do i think is to build coalitions with other countries to make sure that rather than have 180,000 troops overseas, fighting a nonstate actor that weve got special forces and intelligence assets and local partners and isil is being defeated in syria and iraq, but were going to have circumstances in which small cells, individuals, are going to be able to do some harm to innocent people. And weve got to do everything we can to prevent it. One of the best ways of preventing it is making sure that we dont divide our own country. That we dont succumb to fear. That we dont sacrifice our values. And that we send a very strong signal to the world and to every american citizen that were in this together. Explain how we would sacrifice our values specifically by being divided. Well, look. If we start engaging in the kinds of proposals weve heard from mr. Trump or some of his surrogates like mr. Gingrich where we start suggesting that we would apply religious tests to who could come in here, that we are screening muslimamericans differently than we would others, then we are betraying that very thing that makes america exceptional. And that by the way has helped to insulate us from some of the worst patterns of terrorist attacks, because the muslimamerican community here feels deeply american and deeply committed to upholding the rule of law. And working with law enforcement. And rejecting intolerance and extremism thats represented by the perversions of islam that isil is sending out through the internet or carrying out in the middle east. But that requires leaders, political leaders, religious leaders, business leaders, all of us, to send a very clear signal that we are not going to be divided in that fashion, and i think the kinds of rhetoric that weve heard too often from mr. Trump and others is ultimately helping do isils work for us. He was the chief birther in america, questioning whether you whats your reaction to the fact that hes the nominee of the Republican Party . Well, i think i think it says something about whats happened to the Republican Party over the course of the last eight, 10, 15 years. If you think about what a bob dole or a jim baker or a howard baker or a dick lugar or a colin powell stood for. They were conservative, they were concerned about limited government and balancing budgets and making sure we had a strong defense. But they also understood that our system of government requires compromise, that democrats werent the enemy, that the way our Government Works requires us to listen to each other. And thats not the kind of politics that weve seen practiced. I think all too often. Do you think the majority of American People feel safe, that the world is safer after well, i think right now weve gone through a really tough month. And that happens sometimes. Weve had a terrorist attack in orlando, although it does not appear externally motivated, but a deranged man killing scores of people. Youve had the tragedies that happened in minnesota and baton rouge. Police officers targeted, both in dallas and baton rouge. And the senseless violence that took place in nice. If thats what youre consuming, thats what youre seeing on a daytoday basis for the last month, i think its understandable that people are concerned. What i think is important for leaders to do is to let the American People know they are right to be concerned, weve got to make sure that our Police Officers are protected in a very tough job, that our criminal Justice System operates the way it should and without bias, that were doing everything we can to go after terrorists, but its also important for the American People to remember that our crime rate in this country is much lower than it was in the 80s or the 90s or when i first took office. That immigration rates are substantially lower than they were when Ronald Reagan was president. That as serious as these terrorist attacks are, the fact of the matter is that the American People are significantly more safe now than they were before all the work that weve done since 9 11. And so maintaining that perspective i think is absolutely critical. And trying to fan fears simply to score political points i think is not in the best interests of the American People. You had a very strong reaction to Donald Trumps criticism of you for not using the phrase radical islam. But in 2008 when you were a candidate for president , you did use the term radical islam. Why did you stop . You know, this is an interesting example of where something that shouldnt be an issue gets magnified. The fact of the matter is that ive never been politically or particularly concerned with the phrase. What ive been more concerned about is how do we stop violent extremists from killing us . The reason that i havent used the particular phrase radical islam on a regular basis is because in talking to muslim allies, in talking to the muslimamerican community here, that was being heard as if we were ascribing to crazy groups like isil or al qaeda the mantle of islam. And since we need them as allies, i think its useful for us to listen to how the president of the United States words and messages are being received. Because if were going to defeat those organizations, we need help from the billionplus muslims in this world so that they can help root out this perversion of islam thats taken place. Speaking of allies, donald trump had a response and a view about nato. Yes. He said if the baltic nations were attacked that he might not defend unless they were paying their dues. Youve talked about free riders, countries that rely on u. S. Defense without pulling their share. So why arent those similar thoughts, if not playing out a little bit differently, but the same thought . Well, i think that anybody whos been paying attention knows theres a big difference between challenging our european allies to keep up their defense spending, particularly at a time when russias been more aggressive, and saying to them, you know what, we might not abide by the central tenet of the most Important Alliance in the history of the world, one that was built by democrats and republicans and has been a cornerstone of u. S. Foreign policy since the end of world war ii. For mr. Trump, who has in the past suggested that americas weak and not looking out for its allies, to then maybe not have enough information or understanding to go out and say that america might not stand by its solemn commitment to protect those same allies who stood with us after 9 11 when we were attacked, i think is an indication of the lack of preparedness that hes been displaying when it comes to foreign policy.

Ten people were arrested at towns and cities across the country. Ben tracy has the latest. Reporter with the eyes of the world folk skulsed on rio the olympics present an irresistible target for terrorists. Brazils defense minister says the men arrested were in the preparation phase of their plot. Although no particular olympic site was mentioned. Authorities say the men were involved in an online group called the defenders of sharia, did not know each other personally, but were talking about getting weapons and martial arts training. There is a concern about terrorism. Reporter robert mugga is a security expert in rio. Brazil is an enormous country, theres no surveillance in many areas of the country. Youve got countries on the border which we know illegal goods are being trafficked. Reporter Brazils Federal Police are monitoring about 100 people for possible links to terror groups, mainly along the border in paraguay and argentina, where weapons easily and often flow into the country. For the past week Security Forces have been conducting highprofile drills in rio, training for attacks on the citys trains and airport. 85,000 police and soldiers will patrol the city during the games. Due in part to a recent surge in muggings and shootings in rio. But these arrests make it clear rio will have to be ready for multiple threats. In todays world you never know.
