On November 22, 1963, the Johnsons were accompanying the Kennedys in Dallas when President Kennedy was assassinated; they were two cars behind the President in his motorcade. Lyndon was sworn in as president on Air Force One two hours after Kennedy died, with Lady Bird and Jacqueline Kennedy by his side. Afterward, Lady Bird created a tape on which she recorded her memories of the assassination, saying it was "primarily as a form of therapy to help me over the shock and horror of the experience." She submitted a transcript of the tape to the Warren Commission as testimony. LBJ advisor Abe Fortas had made notations on her document to add detail. In their plans for their trip to Texas, the Johnsons had intended to entertain the Kennedys that night at their ranch.
