2024 Joe Biden–Donald Trump presidential debate

A debate between Democratic U.S. President Joe Biden and former Republican president Donald Trump was held on June 27, 2024. Hosted by CNN, it was the first debate of that year's presidential election.

Biden's performance in the debate, which was widely considered by media and political experts to be the poorest of any major party nominee in modern American history, raised substantial concerns about whether he would be capable of serving a second term as president. During the days and weeks following the debate, Biden declined in the polls and faced pressure from within his own party to end his presidential campaign. On July 21, Biden ultimately withdrew from the race and immediately endorsed Vice President Kamala Harris to replace him as the party's presidential nominee. However, Harris went on to lose the general election to Trump.
