Bob Graham has accomplished a lot in his career. He served as governor, then senator  of Florida, and on the 9/11 Congressional Inquiry Commission. Former Sen. Graham can now add “novelist” to his long list of achievements.  His new book is called “Keys to the Kingdom: A Novel of Suspense.” And while it’s fiction, some of the events and characters in the book bear a striking resemblance to former Graham’s real life.   Former Sen. Bob Graham joins us today in the studio.
