Biden live updates as decision to drop out and endorse Kamala Harris upends 2024 presidential race

President Biden is dropping out of the presidential race and endorsing Vice President Kamala Harris to be the Democratic nominee in the 2024 presidential race, he announced Sunday, upending the campaign and hurtling Democrats toward a complicated and potentially divisive process to replace him. 

"It has been the greatest honor of my life to serve as your president," Mr. Biden wrote in a letter to the American people posted to social media. "And while it has been my intention to seek reelection, I believe it is in the best interest of my party and the country for me to stand down and to focus solely on fulfilling my duties as president for the remainder of my term."

In a separate post, he wrote: "My very first decision as the party nominee in 2020 was to pick Kamala Harris as my Vice President. And it's been the best decision I've made. Today I want to offer my full support and endorsement for Kamala to be the nominee of our party this year."
