Actress Sigourney Weaver is the next speaker and is discussing climate change.
O'Malley said Hillary Clinton and Tim Kaine are as tough as they come. But Donald Trump is a different story. ... He makes his followers fearful of tomorrow. He feeds off of a deep-seated and dangerous anger.
"My fellow Democrats anger and fear had their moment last week. Now it’s our time," he says to delegates. The crowd cheers.
Actress Weaver is narrating a video playing in the arena. After discussing the effects of climate change on the U.S., it switches to Hillary Clinton speaking about clean energy for the future.
