Stars Come Out for Hillary Clinton at DNC in Philadelphia

The group used its star power to try and attack Trump's candidacy.

"It takes grit and it takes grace," she said.

Comparing Clinton to other women who fought to make history, Streep said, "that's Hillary... that's America."

She introduced a video that compared Clinton's run for the presidency to other important moments in American history.

Ferrera appeared on stage with Dunham and said that Trump would "make America hate again," stressing the dangers that they said he would pose to Latinos and women.

Keys closed the night with a performance of her single "Superwoman," which she dedicated to mothers who have lost their sons to gun violence.

"Here in this moment... for us," Keys tweeted before going on stage to perform.
