President Joe Biden's campaign argues that concerns about the 81-year-old Biden's health are exaggerated because the media ignored his declining health until his performance in the presidential debate, The Washington Post reported.

Ahead of the debate, the White House denounced a video showing the president frozen at a fundraiser and then escorted offstage by former President Barack Obama as a “cheap fake.” Now attendees at the event, including George Clooney, are raising alarms about the president's job performance and decline on the night of the event. according to To the Washington Post.

But the president's campaign staff has dismissed the comments from concerned donors and supporters as “unfair” and “hindsight,” according to The Washington Post.

“Several reporters were present when the president spoke with Jimmy Kimmel at a fundraiser in Los Angeles,” campaign spokeswoman Lauren Hitt told The Washington Post. “No one covered this at the time.”

Concerns began to surface among attendees after Clooney wrote an op-ed in The New York Times calling for him to drop out of the presidential race because of what he witnessed at the fundraiser.

“Over the last four years, he's won a lot of the battles he's faced,” Clooney said. I have written “But the one battle he can't win is the battle against time,” he wrote in a New York Times op-ed. “No one can win that. It's heartbreaking to say this, but Joe Biden, who I was with at a fundraiser three weeks ago,It's no big deal“Biden in 2010. It wasn't even Joe Biden in 2020. It was the same guy we all witnessed in the debates.”

Hours later, Obama's chief strategist David Axelrod and Obama campaign speechwriter Jon Favreau corroborated Clooney's account.

“For those of us who were at the fundraiser, it wasn't a surprise,” Favreau told CNN.

Attendees noticed the president's frailty even before he took the stage at the fundraiser, six attendees told The Washington Post. Biden “appeared frail” in the meet-and-greet line and stumbled while making small talk, the six sources told the outlet. Some who met the president for the first time told The Washington Post they were “shocked” by how weak he looked.

Other donors “struggled” to tell friends the truth about Biden's decline after the event, according to The Washington Post, which reported that President Obama stepped in to rescue Biden after the president stuttered and stumbled during his opening remarks.

“We were worried that telling the truth — that President Biden was stiff, dull and, dare I say it, weak — would cost us support for the president,” one donor told the outlet. “Lying was painful. Now we realize we weren't the only ones hiding what we were going through.”

With the president's political future at stake, Biden's team scrambled to stage public remarks, including a news conference at the NATO summit. Though Biden made some damaging gaffes, he managed to dispel low expectations and drown out calls for his resignation.
