Author Michael Wolff has claimed in a lawsuit that First Lady Melania Trump threatened to sue him for over $1 billion in damages if he didn’t retract Jeffrey Epstein-related statements he made about her.

Wolff said in the lawsuit that Melania Trump’s threat to sue came over statements he made to “The Daily Beast” and in three videos published on social media, although he added that some statements were incomplete phrases and were taken out of context.

The lawsuit came on Tuesday, the deadline set by Melania Trump’s lawyer for Wolff to retract statements, issue an apology and pay damages to his client.

Through his lawsuit, Wolff announced his intention to use the legal action to put the president and his wife under oath to answer questions about Epstein.

Wolff conducted interviews with Epstein before his death. The lawsuit noted that Wolff never said Melania Trump was involved in any of Epstein’s crimes.

Among the statements the lawsuit said were true were those saying Melania Trump was “very involved” in Epstein’s social circle, where she met her future husband, and that it was fair to question how Melania Trump fits into the Epstein story.

Wolff has published a dozen books, including four bestsellers about the president.
