Legend has it that Warren G. liked a “quickie” in a large White House closet with one of his mistresses. He would post a Secret Service agent outside the door to prevent anyone from interrupting his trysts. Guess he never learned the cigar trick.
In that sense, Harding may have been the first President to come out of the closet, in a literal sense.
What about Fiddle and Faddle swimming in the WH pool with JFK?
