Biden pushes party unity as he resists calls to step aside, says he'll return to campaign next week

U.S. President Joe Biden on Friday appealed for party unity to take on former U.S. president Donald Trump's 'dark vision,' working to hold off pressure from Democrats at the highest levels for him to bow out of the 2024 election to make way for a new nominee and avoid widespread losses.

A rapidly growing chorus of Democratic lawmakers called Friday for U.S. President Joe Biden to drop his reelection bid, even as the president insisted he's ready to return to the campaign trail next week to counter what he called a "dark vision" laid out by Republican Donald Trump.

As more Democratic members of Congress urged him to drop out -- bringing the total since his disastrous debate against Trump to nearly three dozen -- Biden remained isolated at his beach house in Delaware after being diagnosed with COVID-19. The president, who has insisted he can beat Trump, was huddling with family and relying on a few longtime aides as he resisted efforts to shove him aside.

Late Friday, Ohio Sen. Sherrod Brown, a Democrat who is in a tough race for reelection, called for Biden to step aside.

Brown said in a statement that he agrees with "the many Ohioans" who have reached out to him. "I think the president should end his campaign," he said.

And in a statement later Friday, Rep. Morgan McGarvey, D-Ky., also called on Biden to drop out while saying, "there is no joy in the recognition he should not be our nominee in November. But the stakes of this election are too high."

Biden said Trump's acceptance speech at the Republican National Convention showcased a "dark vision for the future." The president, seeking to move the political conversation away from his fate and onto his rival's agenda, said Friday he was planning to return to the campaign trail next week and insisted he has a path to victory over Trump, despite the worries of some of his party's most eminent members.

"Together, as a party and as a country, we can and will defeat him at the ballot box," Biden said. "The stakes are high, and the choice is clear. Together, we will win."
