The question is certainly right in that the effect of Jackie marrying Onassis was not good for their relationship. Although Lee did conceal what it meant to her, I think she suffered a good deal from it. I don't know what Gore Vidal said to Hillary Clinton. I admire Jacqueline Kennedy Onassis so much and I am eager to learn more. I understand she did some paintings but have never seen any.
Paintings are sort of a window to the soul.
Yes, I have seen paintings by Jackie. They're Jackie in her little-girl mode. Regarding the journal, I have to say I do not know. I imagine the Schlesinger tapes are also embargoed at least until that date. Where it is now, I don't actually know.
