First lady Melania Trump is demanding that Hunter Biden retract and apologize for comments that linked her to disgraced financier and sex trafficker Jeffrey Epstein.

She is seeking $1 billion in damages over comments Hunter Biden, the son of former President Biden, made in an interview last month with YouTube personality Andrew Callaghan.

In the July conversation, the younger Biden alleged Epstein was the one who introduced the first lady to her husband President Trump, citing author Michael Wolff, who has been regularly ridiculed by the president and others.

In a letter dated Aug. 6, an attorney for Trump called the comments from Biden, "false, disparaging, defamatory" and "extremely salacious."

In a new interview posted to YouTube on Thursday, Callaghan held the letter from Melania Trump's attorney and offered the former president's son an opportunity to apologize to the first lady.

"Uh, f--- that. That’s not gonna happen," Hunter Biden responded.

Fox News Digital first reported on the letter from Melania Trump's attorney.

The president's connections to Jeffrey Epstein have been in the spotlight for weeks amid a push from lawmakers on both sides of the aisle for the government to release more information about the Epstein case — most notably after the Justice Department and FBI issued a joint statement concluding that he did not keep a "client list" and ruled that his 2019 death was a suicide.

Epstein, accused in several cases of sex trafficking young girls, ran in high-powered circles with figures that included Trump, former President Clinton, Britain’s Prince Andrew and a number of other celebrities and wealthy people. The late financier's associate, Ghislaine Maxwell, has been convicted of sex trafficking and is serving a 20-year prison sentence.

Trump said previously that he had a falling out with Epstein after he "stole" workers from his Mar-a-Lago resort.
