Kaine explains how he got into politics, winning a city council race more than 20 years ago.
"I've said ever since – if I'm good at anything, it's because I started at the local level, listening to people, learning about their lives and trying to get results," he says, getting a huge cheer from the delegates.
Kaine's comment that he worked on a Senate committee with Bernie Sanders brings chants of "Bernie!"
"Hillary Clinton and I are compañeros del alma. We share this belief: Do all the good you can. Serve one another. That's what I'm about. That's what you're about. That's what Bernie Sanders is about. That's what Joe Biden is about. That's what Barack and Michelle Obama are about. And that's what Hillary Clinton is about," Kaine says, getting the crowd on its feet cheering.
Kaine joins in with the crowd chanting, "Si se puede."
