Some of Biden’s upcoming fundraising events face new uncertainty

A number of President Biden’s fundraising events in the coming weeks are in jeopardy, with a potential event in Wisconsin canceled and an event in Texas in doubt after his poor debate performance against Donald J. Trump.

Mr. Biden’s fundraising schedules are often unpredictable, as the White House and the campaign juggle the complicated logistics of official events with the competing demands of donors and finance staff. But the fallout from his debate performance has added an extra layer of uncertainty, with a growing group of major donors calling on Mr. Biden to drop his re-election campaign and make way for a replacement at the top of the ticket.

The Biden campaign had discussed sending Mr. Biden to Wisconsin for a fundraiser in late July, according to three people with knowledge of the plans. But donors who had pledged to give large sums and attend began pulling out soon after the debate ended.

The campaign had hoped to raise $1 million from the event, but after the debate, campaign officials lowered the event’s goal to $500,000, according to a person involved in organizing it. Even that turned out to be more than Wisconsin donors were willing to give to Mr. Biden. Plans for the event are now off.

Another fundraiser being considered would involve an official event in mid-July at the Lyndon B. Johnson Presidential Library in Austin, Texas, where Biden will celebrate the 60th anniversary of the Civil Rights Act, according to two people with knowledge of the planning.

The fundraiser was to be organized by Luci Baines Johnson, the former president’s daughter. But it is unclear whether the event will go ahead, according to people familiar with the planning.

John Morgan, a Florida attorney who had discussed the possibility of hosting Biden for a fundraising event next month or in September, said campaign officials had not confirmed the details and he had not questioned them.

“I don’t think they know the answer,” he wrote in a text message, suggesting that the growing donor uprising had pushed the campaign’s fundraising efforts into uncharted territory.

The donors who have publicly called for Biden to resign have encouraged others to do the same, he said, warning that “it could become an avalanche.”

Campaign finance officials met in a regular meeting Friday to discuss the current situation, in which Biden faces the prospect of several major donors cutting off their support if he stays in the race. Officials made it clear during the meeting that they were going ahead and planned to continue, two people with knowledge of the matter said.

In a statement, Biden’s campaign finance chairman Rufus Gifford said: “Over the past week, the President has proven he has a strong message and a strong agenda to push. We know our supporters will see his determination and will ensure we have the resources to win in November.”

Noah Mamet, a Biden fundraiser and former U.S. ambassador to Argentina, said Biden’s speech at a rally in Wisconsin on Friday helped “calm down a lot of donors and activists” and underscored the stakes of the election, one of Biden’s core messages.

“He was energetic and went straight to the critics this week,” Mr. Mamet said. “It was a good event to turn the page and get the conversation back to Trump and the crazy things he says every day.”

A campaign official said they saw the strongest start to local fundraising yet in July, the period shortly after the debate.

On a list of final fundraisers circulated to top donors in recent weeks, Mr. Biden himself was only scheduled to attend a July 28 event in Denver hosted by the state’s governor, Jared Polis. Mr. Polis told Mr. Biden at a recent meeting held with Democratic governors that he had heard an outpouring of people wanting the president to end his campaign.

According to the distributed calendar, Biden’s deputies, including Transportation Secretary Pete Buttigieg and Doug Emhoff, the husband of Vice President Kamala Harris, do have fundraising events planned.

Biden is expected to attend two fundraising events in Northern California this month, but neither has been finalized.

One is planned in the Oakland area by Wayne Jordan and Quinn Delaney, two longtime major Democratic donors who are married to and close to Ms. Harris, according to a person with knowledge of the event, which has not yet been finalized.

Many Democratic megadonors, vacationing over the long weekend, have become increasingly tough on Biden’s campaign as they try to figure out what influence, if any, they can exert.

Billionaire tech investor Ron Conway used the phone while vacationing in Europe to encourage his network to push for change at the top of the ticket, according to two people with knowledge of his activities. A memo circulated in recent days among major Democratic donors and aides that made up what the authors, who remain anonymous, call “The Case for Kamala.”

Mr. Biden’s fate has been a topic of discussion on the Fourth of July party circuit. At a private party this holiday weekend in the Hamptons, Senate Majority Leader Chuck Schumer was approached by a major Democratic donor and asked for an update on Mr. Biden’s fate. Mr. Schumer said his “lips were sealed,” according to a person who witnessed the interaction.

Biden has received support from other wealthy donors.

On Friday, Amy Goldman Fowler, one of her party’s biggest donors who has given more than $27 million to Democrats in her lifetime, told The New York Times that she plans to donate another $400,000 to the Biden Victory Fund, reaching the legal maximum.

“I continue to support President Biden’s re-election campaign and am making my maximum contribution to his campaign today,” said Ms. Goldman Fowler, who typically prefers to remain in the background.
