The Justice Department’s Office of the Inspector General is beginning an audit to determine whether the agency followed the law in its release of the Epstein files, it announced Thursday.

“Our preliminary objective is to evaluate the DOJ’s processes for identifying, redacting, and releasing records in its possession as required by” the Epstein Files Transparency Act, Deputy Inspector General William M. Blier, who is running the office, said in a statement.

Lawmakers from both parties have accused the Justice Department of failing to release all of the required files related to the deceased convicted sex offender Jeffrey Epstein and his associate Ghislaine Maxwell in compliance with the law.

The act required the Justice Department to release nearly all of its files related to Epstein within 30 days of President Donald Trump signing it into law in November. There were some exceptions, including to protect the privacy of victims and to avoid jeopardizing ongoing federal investigations.

Millions of files have yet to be released, and an explanation has not been given for the redactions on files already released, according to Rep. Ro Khanna, who sponsored the bill along with Rep. Thomas Massie. Khanna said he is demanding answers from acting Attorney General Todd Blanche and former Attorney General Pam Bondi.

“I wrote a letter to Blanche last week asking where the remaining 3 million files are and why the DOJ has failed to explain their redactions, as required by Rep. Massie and my law,” Khanna wrote in a statement. “The survivors and the American people deserve transparency. The audit must address this and Bondi and Blanche should come to the committee to answer questions.”

The Justice Department did not immediately respond to a request for comment but has previously said it will not release additional files, citing active investigations and victim protection. In January, following the release of more than 3 million pages of records, Blanche said the DOJ had reached the “end of a very comprehensive document identification and review process to ensure transparency to the American people and compliance with the act.”

Lawmakers have criticized how the department handled the release, saying that the documents did not properly protect victims’ identities and that some redactions went beyond the scope allowed under the law.

Khanna and Massie previously said that when they reviewed unredacted files, they saw the names of six men who were “likely incriminated” in the files, but that those names were redacted in the public documents.

“We already know the Department of Justice failed to comply with the disclosure requirements of the Epstein Files Transparency Act under former Attorney General Bondi and they continue to withhold required documents under Acting Attorney General Blanche,” Massie said in a statement Thursday.

Bondi faced scrutiny over her handling of the files before she was fired this month. Members of both parties accused the department during a February oversight hearing of not properly concealing survivors’ information.

Following the hearing, Bondi also came under fire for pictures that appeared to include a list of the documents Rep. Pramila Jayapal had looked at during her visit to see the files.

Before Bondi was fired, the House Oversight Committee subpoenaed her to testify in April, but she has yet to do so.
