Author Michael Wolff says his explosive lawsuit against Melania Trump will lift the “dark curtain” on the “secrets” entangling the first lady, President Donald Trump, and Jeffrey Epstein.

The Trump-biographer and co-host of the Daily Beast’s hit podcast, Inside Trump’s Head, sued Melania on Tuesday, accusing her of assaulting his free speech and trying to stifle “legitimate inquiry” into the late convicted sex offender.

In the latest episode of the podcast, Wolff told co-host Joanna Coles that his lawsuit, filed in a New York State court, could expose new layers of the Trumps’ relationship with Epstein thanks to the subpoena powers it gives him.

“I can subpoena the first lady, the president, and anyone else who might shed light on the relationship of Donald Trump and Melania Trump to Jeffrey Epstein,” the best-selling author said. “In other words, this might be a way to actually get to the bottom of this story, to open the curtain, the dark curtain. And we’ll see how they feel about that.”

Wolff is asking the court for permission to question Trump, 79, whose years-long friendship with Epstein has drawn scrutiny, under oath. He is also seeking to depose Melania, 55.

“This lawsuit is an opportunity to reconstruct their lives together,” he said. “This is precisely what Donald Trump wants covered up.”

Wolff, 72, who interviewed Epstein about the president in 2017 while researching his book Fire and Fury: Inside the Trump White House, recalled that many of their conversations revolved around “the real closeness, the intimacy” between Trump and Epstein.

According to Wolff, Epstein revealed that he and Trump were “involved in every aspect of each other’s lives, social lives, sexual lives, business lives,” over the course of their friendship, which lasted from the 1980s through the 2000s.

The Daily Beast has reached out to the White House for comment.

Wolff also said he plans to subpoena various documents on the disgraced financier, calling it a “back door” to the “Epstein files” that Democrats and some MAGA Republicans have been chasing.
