WASHINGTON (AP) — The Department of Justice has expanded its review of documents related to the convicted sex offender Jeffrey Epstein to 5.2 million as it also increases the number of attorneys trying to comply with a law mandating release of the files, according to a person briefed on a letter sent to U.S. Attorneys.

The figure is the latest estimate in the expanding review of case files on Epstein and his longtime girlfriend Ghislaine Maxwell that has run more than a week past a deadline set in law by Congress.

The Justice Department has more than 400 attorneys working on the review, but does not expect to release more documents until Jan. 20 or 21, according to the person briefed on the letter who spoke on the condition of anonymity because they were not authorized to discuss it.

The White House did not dispute the figures laid out in the email, and pointed to a statement from Todd Blanche, the deputy attorney general who said the administration’s review was an “all-hands-on-deck approach.”

Blanche said Wednesday that lawyers from the Justice Department in Washington, the FBI, the southern district of Florida, and the Southern District of New York are working “around the clock” to review the files. The additional documents and lawyers related to the case was first reported by The New York Times.

“We’re asking as many lawyers as possible to commit their time to review the documents that remain,” Blanche said. “Required redactions to protect victims take time but they will not stop these materials from being released.”

Still, Attorney General Pam Bondi is facing pressure from Congress after the Justice Department’s rollout of information has lagged behind the Dec. 19 deadline to release the information.

“Should Attorney General Pam Bondi be impeached?” Rep. Thomas Massie, a Kentucky Republican who helped lead the effort to pass the law mandating the document release, asked on social media this week.

Democrats also are reviewing their legal options as they continue to seize on an issue that has caused cracks in the Republican Party and at times flummoxed President Donald Trump’s administration.

Senate Democratic leader Chuck Schumer said on social media that the latest figures from the Department of Justice “shows Bondi, Blanche, and others at the DOJ have been lying to the American people about the Epstein files since day one” and pointed out that the documents released so far represented a fraction of the total.
