WASHINGTON (Reuters) -President Joe Biden launched his re-election bid on Tuesday with a promise to protect American liberties from "extremists" linked to former President Donald Trump, who he beat in 2020 and might face again in 2024.

Biden made his announcement in a video released by his new campaign team that opens with imagery from the Jan. 6, 2021, attack on the U.S. Capitol by Trump's supporters.
