Other than JFK and Bill Clinton, no other fornicators that we know of did their sexcapades in the White House.
LBJ.
Not even FDR who seems to have had three possible extra-marital relationships while president?
Don’t forget about Reggie Love...makes one wonder.
We may need to add Warren G. Harding to that list if Nan Britton is to be believed.
But in JFK’s case: He took a virgin 19 year-old intern to Jackie’s bedroom to make her an ex-virgin. That same Mimi Beardsley was upstairs in the White House residence, spending the night, while JFK was huddling with top advisors during the Cuban Missile Crises.
