Jeffrey Epstein’s brother doesn’t believe the disgraced financier made blackmail sex tapes to extort his powerful acquaintances — but said he did dish him plenty of gossip about them over the years.

“This is just an opinion — I never really believed they existed,” 69-year-old Mark Epstein, the sex offender’s younger brother, told The Post.

“Jeffrey was buying islands in the Virgin Islands. He had his own private 727 [jet]. Do you think he needed to make money by extortion?” Mark said.

“He knew how to make money in the financial world. He knew all the dirty tricks. When he was on Wall Street he learned all the tricks before Wall Street was cleaned up.”

Epstein climbed the banking ranks at Bearn Stearns in the late 1970s, before founding his own Wall Street consulting firm in the early 80s which he used to springboard into the world of major financial players and forge powerful connections.

Since his 2019 arrest, death, and the exposure of his elaborate sex-trafficking ring, theories have expounded alleging Epstein secretly filmed powerful men in compromising positions at his New York City townhouse and other properties, then used the tapes to extort money or favors from them.

Epstein co-conspirator Ghislaine Maxwell even allegedly acknowledged the existence of such tapes — specifically ones of Donald Trump and Bill Clinton — in a 2016 encounter with former 60 Minutes Producer Ira Rosen.

Mark Epstein doesn’t buy such claims.

“I think you could argue that I knew Jeff better than anybody, and some of these stories seem so far fetched,” he said.

“There was not an extensive camera system in the New York House,” he said, explaining that beyond basic security cameras he knew of no hidden surveillance devices in the lavish Upper East Side townhouse.

What we know about the Jeffrey Epstein list of 170 associates

• On Wednesday, documents were released naming 170 associates of accused sex trafficker Jeffrey Epstein. The list included Michael Jackson, magician David Copperfield, Stephen Hawking, former Israeli Prime Minister Ehud Barak and former President Bill Clinton — who an Epstein victim said “likes them young, referring to girls.”
• Disgraced royal Prince Andrew, a known friend of Epstein, was named in the documents and was previously sued by Epstein accuser Virginia Giuffre, who accused Andrew of sexual misconduct toward her. According to one royal family expert, the Firm “will stand beside” the Duke of York “no matter what.”
• Epstein’s former attorney and friend Alan Dershowitz defended the late multimillionaire sex offender’s associates, saying: “None of us knew about his private life that he kept so secret.” Dershowitz, who is on the list, added that no one should be automatically convicted in the court of public opinion simply for showing up in court documents.
• Epstein’s brother, Mark Epstein, told The Post that the ex-business mogul said he could have upended the 2016 election over what he knew about both Donald Trump and Hillary Clinton: “Here’s a direct quote: ‘If I said what I know about both candidates, they’d have to cancel the election.’ That’s what Jeffrey told me in 2016.”
• Only some of the 170 names and their relationships to Epstein have been released. The remainder of the documents will likely become public record throughout the next week.

“I was told there were no cameras in the house — like spycams. But… I wasn’t there,” he conceded.

No such tapes have ever come to light, and neither Clinton nor Trump have been charged with crimes connected to Epstein.

Both men’s names did appear numerous times in the first round of newly revealed documents from Epstein-related lawsuits released on Wednesday.

Clinton’s name appears at least 73 times in the files, while Trump is named four times.

Both men are known to have associated with Epstein and flown on his private jet — later known as the “Lolita Express” for its alleged use in trafficking underage girls — in the 90s and early 2000s.

“I was actually on the plane with Donald Trump and my brother,” Epstein recalled. “Back then, I regularly flew with my brother,” he said, noting it was a normal flight where nothing untoward happened.

However, Mark did admit his brother was a noted gossip and supplied him with a long list of salacious anecdotes about the high and mighty and rich and famous of society.

“Jeffrey used to tell me when something interesting — or, particularly, something funny — happened, because he could share it with me and he knew it wouldn’t go anywhere,” he said, adding that he didn’t want to “smear anyone” by leaking stories.

Though he doesn’t believe in any widespread conspiracies over his brother’s dealings, Mark — who noted he did “not get a penny of Jeffrey’s estate” after he died — is adamant his death was not a suicide as officials have reported it to be.

“I’m not here to defend him. What he did was wrong. But that’s not my concern. My concern is that my brother was murdered,” he said.
