Michael Wolff, author of the tell-all book Fire and Fury: Inside the Trump White House, suggested that President Trump is having an affair.

Comedian Bill Maher asked Wolff on HBO’s “Real Time” on Friday if there was a segment of the book that Wolff is surprised hasn’t gained more attention. In response, Wolff alluded to an anecdote he omitted from the book about Trump that had been circulated and added he did not include it in the book because he could not confirm it was true.
