Kerry Washington is the host on DNC Day 4.
The final day of the Democratic National Convention wraps up with Kamala Harris' big moment: her acceptance speech in which she gets to tell her story to the millions of Americans watching.
Her campaign says, in addition to describing her middle-class upbringing, she will continue to stress optimism and patriotism -- the "politics of joy" -- the overall themes we've heard throughout the gathering.
Sen. Alex Padilla, the first Latino to represent California and Vice President Kamala Harris’ Senate successor, told the crowd "I knew that I had some big Chuck Taylors to fill."
Harris for years has often sported the popular shoe.
White outfits peppered the convention hall here in an ode to suffragists and Harris' historic candidacy.
The outfit motif has been a hallmark of House Democrats, who have used the color to send a signal at major events, such as past state of the union addresses, including this year's, when Democrats sought to make a point about abortion.

Chicago's DJ Metro got the crowd to its feet, dancing to "Lil Boo Thang" by Paul Russell, at the start of the night.
Convention organizers have 100,000 balloons ready to drop at the end of the evening, according to a source with knowledge.
