Famed Teamster Union President Jimmy Hoffa, who had known ties to organized crime, vanished in 1975 and was later presumed dead, but the details of how and when he died remain a mystery. While no one was ever ultimately charged, the FBI did have a few suspects — most notably Hoffa's closest confidant, Charles "Chuckie" O'Brien. Now, O'Brien’s stepson, Jack Goldsmith, argues the intelligence agency had it all wrong in his new book, "In Hoffa's Shadow: A Stepfather, a Disappearance in Detroit, and My Search for the Truth." Goldsmith is also a Harvard law professor, former top lawyer at the Office of Legal Counsel and a former assistant attorney general in the George W. Bush Administration.
