In Part 2 of our interview with James Risen, Pulitzer-winning reporter formerly with The New York Times and now with The Intercept, we discuss more details from his new book, The Last Honest Man: The CIA, the FBI, the Mafia, and the Kennedys—and One Senator’s Fight to Save Democracy. He describes who Senator Frank Church was, revelations from the committee about assassination targets like Fidel Castro in Cuba, Patrice Lumumba in Congo and Ngo Dinh Diem in Vietnam. He also shares new details about the CIA’s MK-Ultra program and elaborates on the impact of the Church Committee in creating new intelligence agency oversight, including the congressional intelligence committees and the Foreign Intelligence Surveillance Court.
