Harvard Law professor emeritus Alan Dershowitz, who once represented disgraced financier Jeffrey Epstein, says his former client’s longtime co-conspirator, Ghislaine Maxwell, “knows everything” about the Epstein case and should be offered immunity to testify before Congress.

The comments come as the Trump administration, which had pledged full disclosure and transparency on the Epstein files, is coming under increasing criticism for failing to deliver.

“She knows everything. She is the Rosetta Stone. She knows everything. She arranged every single trip with everybody. She knows everything,” Dershowitz said in an interview on “Fox News Sunday.”

He added he does not see any harm in offering Maxwell “use immunity” to talk freely about the Epstein case in testimony before Congress.

“If she were just given use immunity, she could be compelled to testify. I’m told that she actually would be willing to testify. And there’d be no reason for her to withhold any information,” Dershowitz said.

“So, I don’t see any negative in giving her the kind of use immunity that would compel her to testify. So, she ought to be summoned in front of a congressional committee,” he added.

Maxwell is serving out a 20-year prison sentence after she was convicted of helping Epstein carry out his sex trafficking scheme. She is appealing her conviction.

Epstein was charged with federal sex-trafficking crimes in 2019 but died by suicide in his jail cell before his case made it to trial. He had pleaded guilty to prostitution charges in state court a decade earlier as part of a plea deal that was broadly criticized as too lenient.

The Justice Department, taking heat after indicating that no further disclosures on the case would be coming, asked a federal court on Friday to unseal grand jury testimony from the prosecutions of Epstein and Maxwell, but Dershowitz said he doesn’t expect much new information to come from that testimony.

“Grand jury information is narrowly tailored by prosecutors only to provide sufficient evidence to result in an indictment. They don’t want to put a lot of material in the grand jury because that would then have to be produced to the defendant,” he said.

“So, what’s much, much more important is discovery information, depositions and other kinds of things that came out of the Ghislaine Maxwell case, that came out of other cases that were pending in front of federal judges,” he continued.

“All of that should be revealed as well,” he added. “And as long as there’s nothing redacted about the accuser’s lack of credibility, then the public has the right to make its own decision. Just because somebody’s name is mentioned doesn’t really mean very much.”

Lawmakers have put forth multiple measures seeking to compel the Department of Justice to release further records on Epstein. Reps. Thomas Massie (R-Ky.) and Ro Khanna (D-Calif.) have vowed to file a discharge petition to force a vote on their bipartisan resolution that calls for the disclosure of Epstein files.

The latest development in the saga came last week when The Wall Street Journal reported on what it called a “bawdy” note that President Trump had allegedly sent Epstein for his 50th birthday. Trump forcefully denied the letter and sued over the report.
