Former President Donald Trump on Monday quipped that President Joe Biden did not remember dropping out of the presidential race on Sunday and that he had attempted to carry on as president as though nothing had happened.

Biden announced on Sunday that he would not seek reelection and endorsed Vice President Kamala Harris to succeed him as the party standard bearer. He had faced mounting pressure from Democratic heavyweights to do so in the wake of a disastrous debate performance that renewed concerns over his age and mental acuity.

"It’s a new day and Joe Biden doesn’t remember quitting the race yesterday!" Trump posted on Truth Social. "He is demanding his campaign schedule and arranging talks with Presidents Xi of China, and Putin of Russia, concerning the possible start of World War 3. Biden is 'sharp, decisive, energetic, angry, and ready to go!'"

Trump further suggested that it had not been Biden's decision to leave the race.

"The Democrats pick a candidate, Crooked Joe Biden, he loses the Debate badly, then panics, and makes mistake after mistake, is told he can’t win, and decide they will pick another candidate, probably Harris," he also said. "They stole the race from Biden after he won it in the primaries — A First! These people are the real THREAT TO DEMOCRACY!"

The Democratic Party has yet to formally name its nominee.
