Along the way, he offers his plainspoken, first-hand views and often humorous and surprising anecdotes about some of the world's best-known figures, ranging from Elvis Presley to George W. Bush. Both a fascinating narrative and an unprecedented glimpse into history,Known and Unknown captures the legacy of one of the most influential men in public service.
