During a rare Oval Office address to the nation, President Joe Biden said it's best to pass the "torch to a new generation."
"The defense of democracy is more important than any title," Biden said. "Nothing, nothing can come in the way of saving our democracy. And that includes personal ambition."
Said Biden, "I revere this office, but I love my country more."
In his address, he explained why he dropped out of the presidential race and outlined what he hopes to do in his remaining six months in office.
In the meantime, Vice President Kamala Harris is pushing ahead with campaigning for president days after Biden's decision.
With enough delegates secured to become the presumptive Democratic nominee if they keep to their pledges, Harris has held her first campaign rallies. At his first rally since Biden's announcement, Donald Trump attacked Harris while talking to voters in South Carolina.
