Trump facing 'a real problem' inside his house — and he can't outrun it: biographer

President Donald Trump is facing "a real problem" coming from inside his own house that he can't outrun, according to one of his biographers.

Journalist Michael Wolff told Joanna Coles of The Daily Beast on a new episode of their podcast, "Inside Trump's Head," on Tuesday that Melania Trump has become "a matter of serious concern" inside the White House. He cited her recent Amazon-backed movie and her press conference, where she denied having any ties to the disgraced financier and convicted sex offender Jeffrey Epstein, as actions that have raised eyebrows among administration officials.

"So everybody within the White House is like, 'Oh my God, the Melania situation is a real problem,'" Wolff said. "And it has raised all kinds of questions about their marriage, about actually how she came to this country, about the nature of her relationship with Trump and with this guy, Paulo Zampolli."

"That, of course, is now coming out in the last couple of weeks. So, Melania is seen as a problem," he added.

Wolff also warned that the recent attacks the Trumps waged against late-night comedian Jimmy Kimmel will only make matters worse.

Kimmel made a joke that Melania Trump looked as "beautiful as an expectant widow" during one of his shows before the shooting at the White House Correspondents' Dinner last Saturday. The Trumps have since used the event to call for ABC to remove Kimmel from the airwaves.

"There is now the feeling that that has kind of screwed up, and rather than engender sympathy, it's just drawn the lines, drawn more attention to her, more attention to their peculiar marriage, or maybe not quite marriage at all," Wolff said. "And again, the Melania of it all is now under scrutiny and has now become a matter of serious concern in the White House."
