Transcript for Michelle Obama Gives Rousing DNC Speech
We'll move on to last night's drama at the democratic national convention. First lady Michelle Obama as we said wowed the crowd with her takedown of Donald Trump. Then it was Bernie sanders' turn to try to rally his angry supporters behind Hillary Clinton. Cecilia Vega was on the Noor for all of it and joins us now. Reporter: You know it. What a scene it was in here. Bernie sanders Bernie tried to pass the baton vowing to do whatever it takes to help her win but from many he faced open rebellion. Reporter: The man at the center of a political revolution got a three-minute standing ovation. Thank you. Reporter: But overnight sanders' battle cry for Hillary Clinton -- Hillary Clinton must become the next president of the united States. Reporter: -- Met with defiance, supporters in tears, the California delegation openly booing. On stage sanders trying to play mediator. It is no secret that Hillary Clinton and I disagree on a number of issues. That is what this campaign has been about. That is what democracy is about. Reporter: While offstage he pleaded for calm after scenes like this. Reporter: Delegates shouting at each minutes after the gavel kicked off the convention. Even comedian Sarah Silverman lashing out. Let me say to the Bernie or bust people, you're being ridiculous. Reporter: But it was Michelle Obama who stole the show. Our motto is when they go low, we go high. Reporter: Taking on trump. Don't let anyone ever tell you that this country isn't great. That somehow we need to make it great again. Because this right now is the greatest country on Earth. Reporter: And bringing former president bill Clinton to his feet with her endorsement of a previous first lady. And when I think about the kind of president that I want for my girls and all our children, that's what I want, someone who understands that the issues a president faces are not black and white and cannot be boiled down to 140 characters. When you have the nuclear codes at your fingertips and the military in your command, you can't make snap decisions. Reporter: An emotional Mrs. Obama even choking back tears. I wake up every morning in a house that was built by slaves. And I watch my daughters, two beautiful, intelligent black young women, playing with their dogs on the white house lawn. And because of Hillary Clinton, my daughters and all our sons and daughters now take for granted that a woman can be president of the United States. Reporter: You could hear it there, those cheers were just deafening. We're told Michelle Obama was heavily involved in writing and editing that speech and also know the speech writer behind those words is the same person who wrote that speech that was borrowed by Melania trump during last week's republican convention. I can tell you in here that moment when Michelle Obama was on that stage was that one moment that had prolonged, sustained unity in this convention hall last night. It was really amazing to be here in for that. That's right, Cecilia. Thank you.
