Ronald Reagan in the Nude: Former White House Usher Skip Allen Tells All

Skip Allen remembers a private encounter with the president.

While the document was designated "for the President's eyes only," Allen would end up seeing more than he bargained for that day in 1981: a naked president.

“I took it up, and I'm looking for him, and the steward comes out and says, ‘He's in there.’ So I went over and knocked on the door and he said, ‘Come in,’” Allen recalled Reagan saying in an interview with ABC News' Jonathan Karl. “And there he was getting out of the shower. And he was just having a sheet of water on. That's all they had.”

Allen shifted his gaze from the nude Reagan as he extended the document toward the president. “He dried his hands off and he said, ‘Oh, yeah, I'm working through that,’” Allen remembers, Reagan seemingly unfazed by the encounter.

“So, I walked into the bedroom, and the president's just coming out of his dressing room in his underwear,” Allen said. “And Mrs. Reagan said, ‘Oh, Ronnie, you could put on a robe anyway.’ And he looked at her and said, ‘Oh, it's alright. He's already seen me naked once today. We're old friends.’"

Allen remembers a much less friendly rapport with the Clinton's, calling their transition to the White House the most difficult of his time as usher from 1979 to 2004.

“They were a little on the indecisive side as to what they wanted and how they wanted it, and they had to switch around a couple of times before they got things the way they liked it,” Allen said.

Allen’s stories, and those of many other White House residence staff, are revealed in detail in a new book “The Residence,” by author Kate Andersen Brower.
