Vice President Kamala Harris said she will seek the Democratic nomination to replace President Joe Biden, after Biden suddenly ended his campaign and endorsed her earlier Sunday.

“I am honored to have the president’s endorsement and my intention is to earn and win this nomination,” Harris said in a statement issued by Biden’s campaign. “Over the past year, I have traveled across the country, talking with Americans about the clear choice in this momentous election. And that is what I will continue to do in the days and weeks ahead.”

Biden’s endorsement gives Harris a major advantage ahead of the planned vote from convention delegates next month.
