Kamala Harris has launched her campaign for the White House, after President Joe Biden stepped aside Sunday under pressure from party leaders.

The vice president has Biden’s endorsement, and is unchallenged as yet for the Democratic nomination, which will be formally decided at the Aug. 19 convention in Chicago.

“I am honored to have the President’s endorsement and my intention is to earn and win this nomination,” Harris said in a statement. “I will do everything in my power to unite the Democratic Party—and unite our nation—to defeat Donald Trump and his extreme Project 2025 agenda. We have 107 days until Election Day. Together, we will fight. And together, we will win.”

In her statement, the vice president paid tribute to Biden’s “extraordinary leadership,” saying he had achieved more in one term than many presidents do in two.
