2024 election updates: 'I've gotta finish this job,' Biden says

Two-thirds of Americans in a new ABC News/Washington Post/Ipsos poll - including a majority of Joe Biden's own supporters - say he should step aside as his party's presumptive nominee for president given his debate performance two weeks ago. That's even as Biden continues to run evenly with Donald Trump, with no meaningful post-debate change in vote preferences.

Americans divide 46-47% between Biden and Trump if the election were today, almost identical to a 44-46% ABC/Ipsos poll result in April. Among registered voters (though there's plenty of time to register) it's an absolute tie, 46-46%.

Were Vice President Kamala Harris to replace Biden as the Democratic nominee, vote choices are 49-46%, Harris-Trump, among all adults (and 49-47% among registered voters). Harris' 49% is slightly better than Biden's 46%, although she doesn't have a statistically significant lead over Trump.

President Joe Biden will take questions from the media on Thursday at 5:30 p.m. ET, his first press conference since the controversy over his candidacy erupted following his debate performance.

Biden has had fewer pressers with the media than his predecessors and the last time he took questions solo was back in November 2023.

Christiane Cordero has the story.

The upcoming press briefing is being held at the Washington Convention Center, where Biden will spend a third day at the 2024 NATO Summit.

In an opinion piece for the Washington Post published Wednesday evening, Vermont Sen. Peter Welch called on President Biden to withdraw from the November general election. He is the first Democratic senator to do so, writing that "the stakes could not be higher."

"We cannot unsee President Biden's disastrous debate performance," Welch wrote. "We cannot ignore or dismiss the valid questions raised since that night."

The first-term senator said he is calling on Biden to withdraw "with sadness."

"Vermont loves Joe Biden," Welch wrote. "President Biden and Vice President Harris received a larger vote percentage here than in any other state. But regular Vermonters are worried that he can't win this time, and they're terrified of another Trump presidency."
