NEW YORK -- Presidential historian Doug Wead thinks Andersen's sensational revelations could well be true.
He said, It's the sort of thing that's unbelievable but really happens in history. Some of these things we're uncovering right now will move from speculation to fact as time progresses.
Andersen writes that when Jackie first entered the White House, she feared she'd never see her husband.
Instead, sharing both home and office meant that she saw Kennedy many times a day, eventually deciding the White House years were the happiest time of my life.
But Andersen also reports that Jackie knew about all of JFK's women. He says the affairs upset her, but she was willing to turn a blind eye, as long as he didn't publicly embarrass her.
It was his relationship with Monroe that seemed to bother her the most, because, Andersen writes, in large part because Marilyn was a loose cannon who could go public at any time, causing a scandal that would obliterate her husband's reputation, destroy her marriage and hold her up to public ridicule.
He claims that Monroe -- aware her career was fading -- thought Kennedy would marry her.
