BLUE BELL, Pa. (AP) — For his first campaign speech of the year, President Joe Biden has warned that Donald Trump’s efforts to retake the White House in 2024 pose a grave threat to the country. Biden’s speech, near Valley Forge, Pennsylvania, came the day before the third anniversary of the violent riot at the U.S. Capitol by then-President Trump’s supporters aiming to keep him in power. Biden called that Jan. 6 day a moment when “we nearly lost America — lost it all.” He said the presidential race — a likely rematch with Trump, who is the far and away GOP frontrunner — is “all about” whether American democracy will survive.
