Ken Hughes, a researcher at the Miller Center’s Presidential Recordings Program at the University of Virginia and author of Chasing Shadows: The Nixon Tapes, the Chennault Affair, and the Origins of Watergate, has spent the last decade listening to, transcribing, and analyzing hundreds of hours of the Nixon tapes. Hughes spoke to The Daily Beast about how the tapes became public, what’s on them, and the best places to listen to them online.
