An anonymous witness has told the Federal Bureau of Investigation (FBI) that US President Donald Trump admitted to "disappearing" a 12-year-old girl and threatened to disappear another child and kill her family, according to a report.

A report published by the Raw Story news outlet on Saturday revealed that in 2016, an individual using the pseudonym "Tiffany Doe" submitted sworn testimony to the FBI, stating "under penalty of perjury" that she had "personally witnessed" Trump threaten to make a minor girl "disappear" and wipe out her entire family, as he had already done to another 12-year-old girl.

The FBI document detailing the account was released on Friday as part of the Department of Justice`s (DOJ) disclosure of roughly 3.5 million files related to the late sex offender and Trump`s close associate, Jeffrey Epstein.

The release has reignited scrutiny of Trump`s long-standing ties to Epstein and the allegations surrounding them.

"I personally witnessed the Defendant [Trump] telling Plaintiff that she should not ever say anything if she did not want to disappear like the 12-year-old female [name redacted], and that he was capable of having her whole family killed," the FBI document states.

The witness told investigators that she worked for Epstein between 1990 and 2000 and described being subjected to similar threats by Epstein himself, mirroring the intimidation she described Trump directing at the unnamed plaintiff in the unidentified lawsuit.

"I was personally threatened by Mr. Epstein that I would be killed and my family killed as well if I ever disclosed any of the physical and sexual abuse of minor females that I had personally witnessed by Mr. Epstein or any of his guests," the document continues.

"I am coming forward to swear to the truthfulness of the physical and sexual abuse that I personally witnessed of minor females at the hands of Mr. Trump and Mr. Epstein, including the Plaintiff, during the time of my employment from the years of 1990-2000 for Mr. Epstein," the document concludes.

As investigators and journalists sift through the 3.5 million Epstein files, new evidence against Trump has surfaced.

Among them is a "child sex abuse tip" forwarded to the FBI, along with evidence that Epstein associate Ghislaine Maxwell tried to "effectively pimp" a young girl to Trump.

Trump`s entanglement with Epstein has haunted him throughout his second term in the White House.

Multiple documents show that Epstein repeatedly referred to himself as Trump`s "closest friend for 10 years," highlighting the depth of their connection.

Records also reveal that Trump flew on Epstein`s private jet at least seven times during the 1990s, and according to DOJ documents released in December, he may have spent hours alone with one of Epstein`s victims at Epstein`s residence.

Epstein was arrested on federal sex trafficking charges in July 2019 and held at New York City`s Metropolitan Correctional Center.

He reportedly died by hanging in August 2019, despite being under suicide watch following a suspected earlier attempt in July, raising persistent questions about the circumstances surrounding his death.
