Biden, 81, could not reverse growing concerns within his party that he was too frail to serve and destined to lose to Donald Trump in November.
He is backing Vice President Kamala Harris to replace him as the Democratic nominee
“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,” Biden wrote in a letter posted on X. “I will speak to the Nation later this week in more detail about my decision.”
Biden thanked Harris for “being an extraordinary partner” in his letter and then endorsed her in a subsequent post.
“My very first decision as the party nominee in 2020 was to pick Kamala Harris as my Vice President,” Biden posted. “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.”
