Listen to Ted’s interview with Charles Ferguson on his book Presidential Seclusion: The Power of Camp David. Charles spent three and a half years at Camp David as Chaplain and Historian. His book is not about his experiences, but is a history of Camp David from its predecessor the U.S.S. Potomac, to establishment of Sangria-La, the change to Camp David, and presidential use through today. This is a chance to look behind the fences that are opened for few visitors.
