The Richard Nixon Presidential Library and the privately held Nixon Foundation are co-releasing a trove of videotaped interviews with the disgraced former president to mark the 40th anniversary of his resignation following the Watergate scandal.

The 28 minutes of tape released Tuesday detail Nixon's personal turmoil in his final week in office.

The clips were culled from more than 30 hours of tape recorded in 1983, a decade after he had retreated to California and out of the public eye.

In the tapes, a candid and unemotional Nixon talks about the day he made his final decision to resign, the infamous "smoking gun" tape and his family's strong resistance to his resignation.

Portions of the interviews aired in 1983, but most of the footage has been in storage for decades.
