i didn't start anything with the wife? i think heidi cruz is a great person. i think it's the best thing he's got going, and his kids, if you want to know the truth. his father, i don't know his father. i met him once. all i did is point out the fact that on the cover of the national enquirer there's a picture of him and crazy lee harvey oswald having breakfast. >> that was donald trump on the first day of his general election campaign sticking with the approach that got him through the primaries. >> chuck todd came back from cleveland overnight. >> i need to get some clean clothes. >> and a couple hours of sleep, i guess. >> yes. >> what's your take on that, the trump of last night and now -- >> well, it's like trump is trump, you know?

>> it could. all of his kids did well and they were very poised and great character witnesses for him and i think it could -- you know, when you sit here, over time -- it's funny, trump himself said it. they love their daddy. i must not be that bad of a guy. you're like, okay, you're not supposed to say it that way but what he's saying is true. the voters are going to look at their interesting about ivanka's speech, it could have been given to the dnc, issue-wise. she talked about equal pay for women, child care, a lot of big government ideas. government getting involved in those things. look, ivanka herself said she wasn't always a part of one party or another. and the problem is while i thought it was a great introductory piece to him, his speech was very tough, very testosterone. all right? it was a powerful speech but it was a divisive speech. some people cling to it and see it as a solution and other people are rappelled by it. i tell you, he's got a wide gender gap here and there's nothing about that speech that's going to close that. if ivanka had done that soft sell and he had a little softer edge to impact. >> if it's not -- i think at this point, if we only should go into breaking news mode if it's not tim kaine. the confidence level is pretty high for everybody at this point. but -- >> when are we going to hear it? >> i think in the next hour or so. they have not fully leaked out yet. they are going to do it by text message. >> that's exactly what they are doing. we will see the new ticket in miami and if it's kaine, they will show off the fact that he's by lingual. i know it's a good one. i promise you that. >> thank you. for more political coverage, chuck and the rest of the nbc news political team will be in philadelphia this sunday morning for "meet the press" at 10:30 right here on nbc 4. donald trump also called out washington, d.c., in his speech last night and used the district as an example of the city's spike in crime. >> reporter: when he accepted the republican nomination last night, our city found itself in an uncomfortable spotlight. >> in our nation's capital, killings have risen by 50%. >> reporter: trump didn't give specific dates and used the broad term killing. so we decided to take a look at homicide numbers for washington, d.c., starting in 2007. at 181 murders, that's the year that police chief cathy lanier took over the police department. the numbers then declined 2012 at just 88 murders that year. the next couple of years, they were right about 100. but then in 2015, we did see a 54% increase in homicide. >> any homicide, quite frankly, in our city is too many for me. >> reporter: d.c. mayor muriel bowser said the city has created multiple programs to try and knock the numbers back down. >> i just want the new initiative, for example, to attract more police officers who are d.c. residents and are expanding our cadet program. we also work with our communities to put out 1200 security cameras, which also makes neighborhoods safer. >> reporter: when you compare the homicide numbers for july 2015 to where we are now in 2016, murders have actually decreased by about 9% and the mayor's staff says we're now on pace to get back to where we were before 2015. ti coming up, new concerns about the zika virus here in the u.s. doctors are worried about its spread. summer vacation is so precious. here in montgomery county, it soon could be changing. i'm scott macfarlane. a big p hey how's it going, hotcakes?
