In Released Tapes, A Newly Candid Jackie O.

Hours of never-before-heard interviews with Jacqueline Kennedy Onassis have been released to the public for the first time.

The recordings were made in 1964, just months after the assassination of President John F. Kennedy.

At one point in the interview with historian Arthur Schlesinger, the former first lady speculates on what her husband might have done when his presidency ended.

She says she encouraged him to return to the U.S. Senate, and even spoke with family members about the possibility of Sen. Edward M. Kennedy giving up his seat, which the younger Kennedy said he would do.

"[A]nd Jack was really wounded when I told him that," she said in the interview. "And he was touched that I cared so much to be so worried but he said, 'No, I'd never never do that, take that from Teddy, how could you think I'd do such a thing?' "

Kennedy Onassis also reveals her opinions about many prominent political figures, including saying her husband cringed at the idea of Lyndon Johnson as president.
