Thousands of Democratic delegates officially made Vice President Kamala Harris their nominee earlier this month, and now have reiterated their choice in a celebratory roll call of states. It's one of a number of unprecedented moments to come as part of the 2024 Democratic National Convention in Chicago, where Democrats solidified their nomination of the party's first Black woman atop its ticket, as well as the first nominee of South Asian descent. Delegates descended on Chicago after a topsy-turvy few weeks for their party, with President Joe Biden — amid growing calls to do so from within his own party — shuttering his campaign and throwing his support behind Harris.
