Biden campaign and Democrats clash as critical weekend looms

US President Joe Biden's campaign reiterated on Friday morning that the president is staying in the race, despite calls from top Democratic leaders for him to step aside as the party nominee.

Mr Biden’s re-election campaign chair Jen O’Malley Dillon appeared on MSNBC's Morning Joe on Friday, telling the program that the president is not withdrawing.

“Absolutely, the president’s in this race,” she said when asked about Mr Biden's plans.

She described him as "more committed than ever to beat Donald Trump" and said he's the "best person" to take on the former president.

Her comments come amid conflicting reports of conversations within Mr Biden's circle and the larger party about the president's future, further confusing public perceptions of the campaign.

Over the last several weeks, the president has been caught in a whirlwind of political pressure to step down: Calls from within his own party's leaders to withdraw from the race, a loss of big ticket donors and the added pressure that his decision could cost Democrats control of Congress.

As his staff defends his campaign, the president is under quarantine at his home in Rehoboth Beach, Delaware. He tested positive for Covid-19 while traveling in Las Vegas earlier this week. Mr Biden is experiencing “mild symptoms”, the White House said.

Since his poor debate performance last month, Mr Biden's perspective on what it would take for him to step down as the Democratic nominee has also evolved.

First telling ABC News' George Stephanopoulos "only the Lord Almighty" would make him stand down, Mr Biden said this week during an interview with BET (Black Entertainment Television) that he would re-evaluate the campaign if a doctor told him he had a serious medical condition.

But according to a campaign memo released on Friday, Mr Biden isn't going anywhere.

"Joe Biden has made it more than clear: He’s in this race and he’s in it to win it," according to the memo. "Moreover, he’s the presumptive nominee — there is no plan for an alternative nominee. In a few short weeks, Joe Biden will be the official nominee. It is high past time we stop fighting one another. The only person who wins when we fight is Donald Trump."

Time is running out for Mr Biden to decide if he will step down.

The Democratic National Convention begins 19 August, but the Democratic National Committee is expected to meet virtually the first week of August to nominate Biden as the official party nominee to meet state ballot deadlines.

The DNC rules committee is holding a meeting on Friday morning to discuss the procedures for the virtual roll-call vote.

On Thursday, Democratic Senator Jon Tester, of Montana, became the second Democrat in the upper chamber to call on Biden to end his re-election bid.

"While I appreciate his commitment to public service and our country, I believe President Biden should not seek re-election to another term," he wrote in a statement on X, formerly Twitter.

Congressman Jim Costa, a Democrat from California, became the second lawmaker on Thursday to call for him to withdraw.

On Friday, five additional House Democrats called for Biden to withdraw from the race.

Democratic congressmen Jared Huffman of California, Marc Veasey of Texas, Chuy Garcia of Illinois and Mark Pocan of Wisconsin released a joint message saying "the most responsible and patriotic thing" Biden could do is "step aside as our nominee".

"With great admiration for you personally, sincere respect for your decades of public service and patriotic leadership, and deep appreciation for everything we have accomplished together during your presidency, it is now time for you to pass the torch to a new generation of Democratic leaders," they wrote in the joint statement.

Illinois Democratic congressman Sean Casten wrote in the Chicago Tribune on Friday that he doesn't think the president can defeat former US President Donald Trump.

"It is with a heavy heart and much personal reflection that I am therefore calling on Biden to pass the torch to a new generation," he wrote.

Reports this week revealed senior Democratic leaders are leaning in the same direction.

Senate Majority Leader Chuck Schumer, House Minority Leader Hakeem Jeffries and former House Speaker Nancy Pelosi have all reportedly expressed concerns during private conversations with Mr Biden about his candidacy. In public statements, Ms Pelosi's staff insist her comments have been misrepresented.

Former President Barack Obama, Mr Biden's previous running mate, has reportedly said Mr Biden's chances of winning the election have greatly diminished.

Lawmakers haven't been the only ones turning their backs to Biden. Big name donors - including actor George Clooney and Disney family heiress Abigail Disney - have closed their wallets.

Despite the defectors, some are sticking by his side.

New York Rep. Alexandria Ocasio-Cortez, one of the most influential progressive voices in the House, has supported Biden over the last few weeks. She broadcast live on Instagram on Friday morning and spoke about the risks of entering the convention without Biden as the presumptive nominee, including potential legal challenges and ballot access deadlines.

The Congressional Hispanic Caucus, which has about 40 members, and the 60-member Congressional Black Caucus, have both met with the president and also indicated their support for his re-election bid.
