vp, she chose the virginia senator because she wanted somebody qualified and that will be candid for her as well. they put the finishing touches on the wells fargo center with big names and a celebrity on stage for a sound check. >> one, two, three, four, five, six, seven eight. >> reporter: the night for sound checks and the house band to get in one last rehearsal. crews are doing final construction and tweaking new sets. for a second, the arena was filled with the sound of silence as everyone paused to listen to paul simon on the stage. >> reporter: after the music legend told "action news" he's looking forward to performing here. >> excited. i think i played here before, but i'm excited. you know, i hope this convention is going to be everything it

promises to be. tough. >> reporter: the reverend jesse jackson gave the themes we are likely to hear. >> turn to each other, not on each other. learn the survivor part, learn to live together. >> reporter: taking a live look inside the wells fargo center, you can see the stage is set for history as hillary clinton is about to become the first woman to head the presidential ticket for a major party. as the delegates rally here inside the convention center, thousands of protesters will be making themselves heard outside the building and throughout the city of philadelphia. "action news" reporter, christie ileto has that part of the coverage. >> letting bernie know, no matter what they do, we are with you on the street. we are with you, bernie. >> bernie or bust. >> reporter: hillary clinton may be the presidential nominee, but bernie sanders supporters are

still backing their guy. thousands pound the pavement for three miles from city hall to fdr park. >> the image is great. it's the bomb. >> reporter: protesters spell out the issues from dnc leaks, clean energy. >> stop the frac jack and don't you pollute no more no more no more. >> reporter: it's a hot issue at independence mall where hundreds protest the steamer. >> i'm an old man. we need water. >> reporter: free bottled water. spray trucks lined. >> it looks like hillary is going to be the democratic nominee for president. can you get behind that? >> i cannot. i will vote for jill stine. >> if there's an alternative, i'm going to take that. >> reporter: that was christie ileto reporting. walter, we'll have more coverage from the wells fargo center in a moment. back to you.

>> thank you, sarah. talk to you in a bit. one of the other big stories we are following is the weather. we'll have extreme heat and thousands of protesters here can expect to find water stations with hydrants to keep people cool. people from across the country, some visitors may be accustom to this heat, but for others, a shock. limit your outdoor time and stay hydrated. with that said, we move to melissa magee with the accuweather forecast. >> the heat rolls on as we get to the start of the workweek. it was hot today. philadelphia, 95, making it another heat wave, number four for the city. it's warm. at 82, 73 to the west in pittsburgh and 83 in richmond, virginia. the level of moisture in the air is creeping up. a dew point of 63.

70 degree dew point numbers tomorrow. the i-95 metro area, we have a heat advisory for the orange shaded counties until 6:00 p.m. resignation of the d

convention. it's supposed to show unity and confidence. it also gave donald trump the opportunity to tweet the democrats are in total meltdown, but the bias media will say how great they are doing. well, they are not doing great today. it was a tough day for hillary clinton and the dnc. but, this is where the story gets to yet another level because the campaign chairman of the clinton campaign says it is the russians who stole and leaked these e-mails from the democratic national committee for the purpose of hurting

hillary clinton and helping donald trump. why might the russians want to help donald trump? well, we remember his statement last week, as president, he wouldn't necessarily defend a nato country under attack until that country or until he could assess that country's financial contributions to the alliance. words that maybe vladimir putin and other russian officials like to hear. this situation has assumed a different dimension and this convention hasn't even started yet. >> reporter: this is hillary's convention. bernie is still looming large, though. >> he is. he has told hillary clinton over the last number of months during the primary campaign, we know that. and we know the platform, not that the platform is necessarily cast and concrete over the months ahead, but it is important during this convention. a lot of the platform is more

bernie than hillary. today, the controversy over superdelegates seems to be going bernie sanders way. the rules committee will appoint a commission, but the final result will be that two-thirds of the superdelegates will be bound by the vote of their state conventions during caucuses and votes four years from now, primaries four years from now. that whole issue of superdelegates, two-thirds of the superdelegates will be bound to candidates, not the way they are now. >> reporter: we expect a different tone here. more star studded. thank you, jim. the convention begins tomorrow afternoon at 4:00 p.m. with the opening gavel. first lady, michelle obama is a featured speaker. tuesday, the role call vote will take place to nominate hillary clinton, officially.
