In a tumultuous social media post, President Joe Biden has announced that he is dropping his reelection bid against Donald Trump. The announcement Sunday throws an element of turmoil into the election just months before voters go to the polls.

Biden’s decision comes on the heels of a poor debate performance that prompted many rank-and-file lawmakers to urge him to withdraw from the race. The president said he will address the American people later this week “in more detail about my decision.”
