Transcript for Michelle Obama, Bernie Sanders to kick off Democratic National Convention
Good evening and it's great to start off another week here together and we begin with several headlines unfolding just as we come on the air. Of course, we are just a short time away now from the democratic national convention. An unconventional convention in so many ways this time around, as the Democrats now make the case for Joe Biden. They do so amid this pandemic. This economic crisis. And tonight, there is news on the virus, Dr. Deborah birx a short time ago. What she wishes the U.S. Had done what she wishes the U.S. Had looked like. The new concern over schools. And the university with a major reversal after what they saw in just a matter of days. There's also news as we come on tonight involving the U.S. Postal service, what president trump is now saying as Americans in small towns and large ask what is going on with the postal service? And just in tonight, former first lady Michelle Obama. A first look at some of what she'll say tonight about Joe Biden. We will also hear tonight from Bernie Sanders, making the push for Joe Biden and kamala Harris, and from Republicans who will take part, too. A well-known Republican governor who ran for president himself now with Biden. So, a big night ahead and with this country facing major challenges ahead, we're going to carefully get to it all. And we begin with Mary Bruce, leading us off tonight. Reporter: Democrats just hours away from a convention like none other and we are now getting a first glimpse at the night's headliner. I know Joe. He is a profoundly decent man guided by faith. Reporter: The DNC releasing part of Michelle Obama's prerecorded address. The former first lady says Joe Biden has what it takes to lead. He will tell the truth and trust science. He will make smart plans and manage a good team. And he will govern as someone who's lived a life that the rest of us can recognize. Reporter: Four years ago, the party was bitterly divided. Now they are eager to show a united front. I think there is overwhelming understanding that Donald Trump must be defeated. Biden must be elected. Reporter: Bernie Sanders will speak tonight, but so will several prominent Republicans including former Ohio governor John Kasich. The goal? To show that Biden can speak to all Americans, not just Democrats. The president is counterprogramming. Those Democrats are not in Wisconsin as planned, trump is. They're making speeches that are taped. Who wants to listen to Michelle Obama do a taped speech? No, you got to have her get up there. Reporter: But Democrats believe voters will connect with messages like this. Joe knows what it's like to struggle, which is why he gives his personal phone number to kids overcoming a stutter of their own. His life is a testament to getting back up and he is going to channel that same grit and passion to pick us all up. Our first look at the former first lady tonight. Let's get right to Mary Bruce, live in Washington. And Mary, Joe Biden, we know, will accept the domination on Thursday, but we're going to hear from him tonight? Reporter: David, we will get a glimpse of the candidate tonight in a prerecorded conversation with racial justice leaders. It's just one of the issues Democrats are highlighting tonight, along with the pandemic and the economic downturn. Three crises where Democrats say the president is failing to lead. David? All right, Mary Bruce, we'll see you later tonight. I hope you'll join the entire political team here at ABC for the democratic convention beginning at 7:00 P.M. Eastern on ABC news live and then at 10:00 P.M. Eastern, right here on the network. And we should point out tonight, the first joint interview with the former vice president Joe Biden and senator kamala Harris is now set. Robin Roberts and I will be conducting the first interviews with Biden and Harris together. The exclusive one-hour special, their first network interviews nest Sunday night, 8:00 P.M. Eastern, right here.
