Singer and songwriter Carole King takes the stage and gives a shout-out to Idaho.
A video is playing, of people speaking to their hopes and dreams for their daughters.
Duckworth speaks about her daughter: "My Abigail already knows women can fly helicopters in combat. And in 102 days, when we elect Hillary, my daughter's first memories of a president will be of a woman." The crowd cheers.
Duckworth says, "By the way, Donald Trump, I didn't put my life on the line to defend our democracy so you could invite Russia to interfere in it. You are not fit to be commander-in-chief."
On Wednesday, Trump urged Russia to search for Hillary Clinton's "missing emails," an action that has brought bipartisan criticism.
