Viewers will hear the former first lady speak with historian Arthur Schlesinger Jr. about life in the White House and with her husband, President John F. Kennedy. The recordings were made months after the president's 1963 assassination and sealed until now.

Originally planned for one hour, the special will now fill two hours in prime time and feature Diane Sawyer's interview with the couple's daughter, Caroline Kennedy.

The ABC special is timed to coincide with the publication of a book about the interviews. The release is also timed to the 50th anniversary of the Kennedy administration.

Jackie Kennedy later married Greek shipping magnate Aristotle Onassis. She died in 1994 at age 64.
