Kennedy, Bobby Kennedy and Marilyn Monroe together.Stoughton was present at the motorcade at which Kennedy was assassinated, and was subsequently the only photographer on board Air Force One when Lyndon B. Johnson was sworn in as the next President.Stoughton knew it was "tasteless," but suggested a photograph needed to be made of the "history-making moment ... and I think we should have it."
