In the days following the assassination, Lady Bird worked with Jacqueline Kennedy on the transition of her husband to the White House. While having great respect for Jacqueline and finding her strong in the aftermath of the murder, Lady Bird believed from the start of her tenure as First Lady that she would be unfavorably compared to her immediate predecessor. On her last day in the White House, Jacqueline Kennedy left Lady Bird a note in which she promised she would "be happy" there.
