What is the proper relationship between the CIA director and the president? How should directors handle arguably illegal orders? How important is the director's role as the nation's honest broker of information during times of crisis?
To get at these questions, David Priess sat down with Chris Whipple, a documentary filmmaker, journalist and the author of two books about the people around the president. "The Gatekeepers," based upon his documentary of the same name, examines White House chiefs of staff, and his new book, "The Spymasters: How the CIA Directors Shape History and the Future," is based on the Showtime documentary "The Spymasters: CIA in the Crosshairs," for which Whipple was the writer and executive producer. They talked about CIA directors through the last several decades and how they've impacted U.S. history and national security.
