About 40 years ago on August 9, 1974, Richard Nixon became the first president to resign from office, facing almost certain impeachment for his involvement in the Watergate scandal.
The most damaging evidence implicating Nixon was found in 3,700 hours of tape, recorded by Nixon himself between February 1971 and July 1973. Only three Nixon staff members knew anything about.
The tapes, which reveal a deeply paranoid and intolerant man, are the subject of a new HBO documentary set to come out on August 4th. "Nixon by Nixon: In His Own Words," directed by Peter Kunhardt.
On Kunhardt's research team included historian Ken Hughes, the author of the forthcoming "Chasing Shadows: The Nixon Tapes, The Chennault Affair, and the Origins of Watergate."
Today they weigh in on the film, and on Nixon's legacy.
Check out a trailer for the film below.
