President Joe Biden announced Sunday that he is dropping his reelection bid against Donald Trump, in a social media post that sent political shockwaves around the country and threw an element of turmoil into the election just months before voters go to the polls.

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

Biden threw his support behind Vice President Kamala Harris to be the Democrats’ new candidate, and she vowed to “earn and win” the nomination.

Republican leaders attacked Harris and said she shares responsibility for the policies of the Biden administration. Former President Donald Trump said Biden “was not fit to run for president,” and he also called for the second debate to be moved from ABC to the Fox News Channel, which is seen as friendlier to him.

Democrats hail Biden’s decision to not seek reelection as selfless. Republicans urge him to resign

Democratic lawmakers are hailing President Joe Biden’s historic decision not to seek reelection as putting his country and his party before himself.

Republicans are calling on him to leave office as well, saying that if he is unable to run, then he’s unable to serve as president.
