California delivers delegates to send Harris over the top in ceremonial roll call
California, Harris' home state, delivered the delegates to send Harris over the top during the ceremonial roll call.
Gov. Gavin Newsom announced that the state is casting its 482 votes for Harris, whom he called a "bright star" whose star has gotten even brighter as she served as the state's attorney general, a U.S. senator and now as vice president.
"Kamala Harris has always done the right thing, a champion for voting rights, civil rights, LGBTQ rights," Newsom said. "It's time for us to do the right thing -- and that is to elect Kamala Harris as the next president of the United States of America."
Harris is already officially the nominee after the DNC held a virtual roll call earlier this month. Still, the symbolism, and the relationship between Newsom and Harris, is significant.
