A U.S. congressional committee said on Tuesday it has issued a subpoena to Attorney General Pam Bondi to testify behind ​closed doors in its probe of the late convicted sex criminal ‌Jeffrey Epstein.

Under the subpoena, Bondi would give a sworn deposition to the House of Representatives Oversight Committee on April 14.

The Justice Department did not immediately respond to a request for ​comment.

Bondi faces accusations that the Justice Department has concealed the names of ​powerful associates of Epstein in its release of millions of documents ⁠related to the late financier, who cultivated close ties to powerful political and business ​leaders before and after he was convicted in 2008 of soliciting prostitution from ​a minor.

Epstein was arrested again in 2019 and died in jail while facing federal sex-trafficking charges. His death was ruled a suicide.

Bondi and her deputy, Todd Blanche, are due ​to give the committee a separate private briefing on Wednesday.

Lawmakers have complained that ​redactions in the Justice Department’s files appear to go beyond the limited exemptions allowed in ‌a ⁠law Congress passed nearly unanimously in November. The department has also declined to publish a large volume of material, citing legal privileges.

Bondi said more than 500 Justice Department lawyers worked on a compressed timeline to review reams of material.

The Epstein ​files have dogged ​Bondi throughout her ⁠tenure as Trump’s attorney general. Some of Trump’s supporters accused her of a cover-up last year when the Justice Department ​said it would initially not release material related to ​its investigations ⁠of Epstein, drawing new scrutiny of Trump’s past friendship with him.

Trump says he broke off ties with Epstein years before his 2008 conviction and has repeatedly said he ⁠did ​not see any evidence of sex trafficking. He ​has not been accused by law enforcement authorities of criminal activity related to Epstein.
