In June, 2006, Donald Trump taped an episode of his reality-television show, “The Apprentice,” at the Playboy Mansion, in Los Angeles. Hugh Hefner, Playboy’s publisher, threw a pool party for the show’s contestants with dozens of current and former Playmates, including Karen McDougal, a slim brunette who had been named Playmate of the Year......At the time of the party, Trump had been married to the Slovenian model Melania Knauss for less than two years; their son, Barron, was a few months old. Trump seemed uninhibited by his new family obligations. McDougal later wrote that Trump “immediately took a liking to me, kept talking to me - telling me how beautiful I was, etc. It was so obvious that a Playmate Promotions exec said, ‘Wow, he was all over you - I think you could be his next wife.’ ”

Trump and McDougal began an affair, which McDougal later memorialized in an eight-page, handwritten document provided to The New Yorker by John Crawford, a friend of McDougal’s.
