McCain Comes from Long Line of Military Service Sen. John McCain, the presumptive Republican presidential nominee comes from a decorated Navy family. Liane Hansen speaks to McCain biographer Robert Timberg about the McCain family's military legacy. Timberg's biography is called, John McCain: An American Odyssey. Timberg himself graduated from the Naval Academy in 1964 and served as a Marine in Vietnam.
