Joe Biden on Sunday dropped out of the US presidential election and endorsed Vice President Kamala Harris as the Democratic Party's new nominee, in a political earthquake that upends an already extraordinary 2024 race for the White House.
Biden, 81, said he was acting in the "best interest of my party and the country" by bowing to weeks of pressure after a disastrous June debate against Donald Trump stoked worries about his age and mental fitness.
The stunning move throws Democrats into fresh turmoil ahead of the November 5 election. But it could also reenergize the demoralized party, with Harris swiftly confirming her goal to become America's first woman president and to "defeat Donald Trump."
