Biden, 80, makes 2024 presidential run official: "Let's finish this job"

President Joe Biden said on Tuesday he will seek a second White House term in 2024, a decision that will test whether Americans are ready to give the 80-year-old Democrat, already the oldest U.S. president ever, another four years in office.

Biden made his announcement in a slickly produced video released by his new campaign team, in which he declares it is his job to defend American democracy. It opens with imagery from the Jan. 6, 2021, attack on the U.S. Capitol by supporters of former President Donald Trump.

"When I ran for president four years ago, I said we're in a battle for the soul of America, and we still are," Biden said. "This is not a time to be complacent. That's why I'm running for re-election."

"Let's finish this job. I know we can," he said.
