WASHINGTON — The Justice Department released 3.5 million pages of investigative material on deceased sex trafficker Jeffrey Epstein Friday, the biggest single tranche of records dealing with the late pedophile.

The files also include at least 2,000 videos and 180,000 images, not all of which were taken by Epstein, according to Deputy Attorney General Todd Blanche, as well as search warrants, previously sealed court documents, flight logs and new emails.

The records include search warrants for the disgraced financier’s Upper East Side mansion, executed on July 6, 2019, and private estate in the US Virgin Islands, searched on Aug. 12 of that same year — two days after Epstein was found dead in a Manhattan jail in what was later ruled a suicide.

A sickening amount of pornographic material was apparently uncovered on compact discs hidden inside a safe in Epstein’s Manhattan residence, with the majority containing titles with “female names” and others scrawled “Girl Pics Nude” or “Misc. Nudes,” per one of the warrants.

Federal agents also took more than two dozen electronic devices from the notorious island Little St. James.

“They include large quantities of commercial pornography and images that were seized from Epstein’s devices, but which he did not take, or that someone around him did not take,” noted Blanche.

“Some of the videos, though, and some of the images do appear to be taken by Mr. Epstein or by others, or around him.”

Other disclosures show the feds served subpoenas for email account data, flight information, credit card purchases and bank records for both Epstein and his now-imprisoned accomplice, Ghislaine Maxwell.

Members of the DOJ and FBI have been working “full time” to put out the documents, photos and videos to comply with a law passed by Congress and signed by President Trump late last year.

“We are also releasing today a letter we are transmitting to Congress and various internal protocols associated with our review,” Blanche added, citing it would include the “legal basis” for any redactions.

“I can assure that we complied with the statute, we complied with the act,” Blanche also said, adding in a swipe at another reporter question: “We did not protect President Trump.”

Congress passed the Epstein Files Transparency Act in a bipartisan vote last November, and Trump signed it into law on Nov. 19.

Disclosures mandated by the legislation have taken more than two months to complete, with FBI agents and federal prosecutors in New York and South Florida working long days to review millions of files and redact victims’ names.

Epstein was found dead in a Manhattan federal lockup on Aug. 10, 2019, while awaiting trial on federal sex trafficking charges.

The 66-year-old was indicted the month before for sexually abusing girls — some as young as 14 years old — and had his New York and Palm Beach, Fla., residences raided.

The financier had previously pled guilty to Florida state charges for soliciting a minor for prostitution in 2008 — and made to register as a sex offender.

Epstein served just 13 months in state prison following his plea, with much of that time spent on work release.

He went on to enjoy relationships with former President Bill Clinton, Microsoft co-founder Bill Gates, Hollywood director Woody Allen and former Israeli Prime Minister Ehud Barak — among others.

Clinton and Gates have both denied all knowledge of Epstein’s crimes and emphasized that their relationship with the purported billionaire was solely concerned with philanthropy.
