have been working not just for this protest but for other demonstrations across the weekend and over the past couple days. again, they sort of cleared the space out pretty nice, pretty smoothly. then seconds after that, you had another crowd of about 200 protesters just took off running through the streets of downtown cleveland led by a group that goes by the name of cleveland anonymous. their job is to agitate police officers and literally take them on a foot chase. that happened but we are told it ended without incident. as far as arrests, officials are basically predicting they would make at least 1,000 arrests per day. that hasn't happened. those numbers haven't started to come in. there were no arrests today and no injuries. one arrest to report that happened on yesterday and that was a woman who had a warrant for her arrest. back to you, scott. >> hour by hour, very quiet seems like every day here in cleveland. dimarco, thanks very much. coming up next, we'll have the russians who

certainly not a choice i would do again. >> you said sorry, i made a mistake. it was the wrong thing to do. >> i have said that, yes. >> and some say, what were you thinking about the national security risk when you made this decision? to cause the capacity and it hasn't been determined that there was no hacking. > well, there's no evidence of it. there is no evidence of it. >> someone suggested that's the reason that they were very good at it because there's no evidence of it and that you exposed as you know. >> charlie, there is no evidence of that. >> comey the director of the fbi said but we don't know. >> that's not what he said. he said -- >> you can't rule it out he said. >> but you can't rule it in either. we could go back and forth on this. i go where the evidence leads. there is no evidence. >> he said careless. >> well, i would hope that you like many others would also look at what he said when he testified before congress because when he did, he clarified much of what he had said in his press conference. and i appreciated that. >> but he said it was sloppy. >> no, he did not. >> he said real sloppiness. >> he said. >> correct me if i'm wrong, someone said what's the definition of careless and he said real sloppiness. >> let me say this. there were three probably at least 300 people on those e-mails. >> right. >> the vast majority of whom are experienced professionals in handling sensitive material. and i have no reason to have second-guessed their decision to send or forward me information. do i wish i hadn't done it in, of course. what is it a mistake, yes. >> was it wrong? >> well, it was wrong because look at what it has generated. >> but was it careless? >> well, i think you would have to say 300 people who communicated with me on e-mail are among the most careful people i've ever had the privilege of working with. >> do you think it contributed and became a controversy because it fed the trust issues? pooh well i'm sure it didn't help. yes, i am sure it didn't help. i am the last person you will ever have to worry about ever not being 100% as specific and precise as i can be. so that nobody ever raises any questions like that ever again. >> do you believe donald trump is dangerous? do you believe donald trump is not fit to be president. >> i think he has shown that he is dangerous. that he poses -- >> in what way. >> well, in, several ways. when someone running for president says in the most offhand way he doesn't really care whether other countries get nuclear weapons, including saudi arabia. >> japan. >> japan. but let's focus on saudi arabia. we have done everything we can democratic and republican administrations going back decades to try to prevent the proliferation of nuclear weapons. that casual indifference to the worst weapons that we have ever created in the world is dangerous. it's either a lack of knowledge about what he's saying means or it's an indifference to the power that he is seeking. and i saw in a long article that donald trump, being near the nuclear code, would pose a danger to civilization. that's not me. i do agree with that, charlie. look, i don't say that lightly and i don't say it with any satisfaction. >> donald trump with his finger on the nuclear bomb would be a threat to civilization. >> he has shown no self-discipline, no self-control no, sense of history, no understanding of the limits of the kind you have power that any president should impose upon himself. he has known none of that. let's return to torture. you know what? i will order the american military to commit war crimes. let's pull out of nato. we don't need them. what he has laid out is the most dangerous, reckless approach to being president than i think we've ever seen. i say that. >> the most day, man ever to run for president of the united states. >> i believe that. >> to talk about your husband's private life, not his public life, is unfair? >> they can talk about whatever they want to talk about, about but we're not responding. you know, republicans have tried this now for a very long time, and i'm happy to have them keep trying it. it hasn't worked out so well for them. >> you need a vice presidential running mate. >> i do. are you interested? i mean, you know there's still time, charlie. you know? you have a lot of the at aretory beauties. you're well-known. you've got a good profile. you speak well. what do you think? that's really. >> are you asking me? >> i'm here to see if you want to be vetted. >> that's what i would fear being vetted. >> that's all right. >> let me talk about -- you have met with them in the last week or so. >> i've met with a bunch of folks. >> how close are you to a choice? >> i have the blessing of having some excellent choices. people who -- here my criterion. would this person be a good president. >> someone like walter mondale, al gore, joe biden. >> excellent choices. excellent people. >> what else is it other than they can do that? everybody on your list has the potential. kaine. you've been with him in virginia. he says he's too boring. >> and i love that about him. he's never lost an election. he was a. >> governor. >> world class mayor, governor, and senator. >> the governor of colorado. >> first class. >> both of these have been vetted. >> i'm not confirming but have a great and high regard for these two people. >> if none of these are on the list, you'll tell me. elizabeth warren. >> amazing. what she has done in a relatively few years to put the agenda of inequality front and center is something that i think we should all be grateful for. >> questioning financial institutions in america. >> but raising the hard issues. you know we're going to have to address. >> so you're comfortable with her. you campaigned with her. she might be a risk choice? >> i'm not categorizing any of these folks. i mean, your flaming people i have a high regard for. >> people you allegedly vetted. >> well, that i've allegedly vetted, yes. >> you vetted them. someone said to me who knows you well, she's looking for someone who she thinks is sort of a projection of her who is a bit wonkish like she is. >> no, no, i do have a fondness for wonks. i will admit to that, but i'm looking for someone who can be a world class president of the united states and who can help me govern. i think they go hand in hand. every one of these people and others whom you haven't mentioned. >> who haven't i mentioned. >> i'm not going to tell you. there are a lot of good folks out there and they bring so many talents and strengths to this choice which is why as i say, i am blessed with a broad group of people to choose from. >> the democratic national convention gets under way monday in
