Ashley Biden, the daughter of former President Joe Biden and First Lady Jill Biden, threatened to sue a former Democratic fundraiser for spilling secret internal discussions about her father’s cognitive and political decline in the 2024 presidential election.

Lindy Li, a former Democratic fundraiser who switched her party affiliation over unheeded warning signs about Biden's decline in the 2024 election, said Ashley Biden posted the threat to Instagram in February of last year.

"They wanted to scare me. That was the goal," Li told Fox News Digital.

Li’s account of the threat, in her view, was one of the many attempts to intimidate her that she received after deciding to speak out about the fear, disorganization and secrecy that had paved the path for Biden to run for re-election in 2024 despite looming concerns about his age. Also, the fact that those threats never materialized is evidence to Li that even her critics recognize the validity of her testimony.

Li described the threat from Ashley Biden in her book, "Unburdened."

"Ashley later threatened to sue me for saying there was a cover-up of her father’s decline, lashing out on Instagram with a bravado so crude it bordered on parody: ‘This woman is a bonavide [sic] liar. Karma is a real bad b----, Lindy,’" she wrote.

"’I don’t know you but can’t wait to meet your a-- in court. Ready for a lawsuit? Let’s go! I won’t put up with this BS anymore.’"

In an interview with Fox News Digital, Li showed screenshots of the post, which she said was taken down just a day later.

She recalled thinking it was odd; beyond the lawsuit threat, Ashley Biden claimed she didn’t know who Li was. But Li had met Ashley Biden on a number of occasions and shared pictures of the two of them with Fox News Digital as proof.

"Doesn’t even pass the smell test," Li said.

As a top fundraiser for both Biden and Harris, Li worked closely with top donors, high-profile members of the party and the Democratic National Committee (DNC). When she decided to go public with revelations about Biden’s age, she said the retaliation began immediately.

"When I went on Shannon’s show to say Biden needs to step aside — and three hours later he did — my access immediately vanished and all my fears about speaking up were justified," Li told Fox News Digital.

"I knew that if I spoke up my life would be ruined and frankly, in that respect, it was. I was never invited to the White House again, never spoke to Biden again. Prior to that, I was invited to the White House every two to three weeks. There was always some event."

When Li brought Ashley Biden’s threat to her legal representation, her lawyers dismissed the possibility but said that the Bidens would likely try to avoid a painful disclosure battle that could drag more details into the public eye over his cognitive decline.

"My lawyer’s eyes lit up: ‘You want her to use you. The discovery would be incredible,’" she recalled. "Truth, after all, remains the strongest shield against defamation."

"Everything I said was true so... I’m still waiting to hear exactly what I said that is legally actionable," Li said.

Representation for Ashley Biden did not immediately respond to a request for comment.
