One of the most public controversies of Sen. Kennedy's life took place in 1969, when he drove a car off a narrow bridge on Martha's Vineyard, Massachusetts.
Sen. Kennedy survived the accident, but Mary Jo Kopechne, Bobby Kennedy's former secretary, drowned. According to police, it took the senator eight hours to report what happened.
Kennedy eventually pled guilty to leaving the scene of an accident. In the book, Sen. Kennedy reflected on the incident and wrote, "That night on Chappaquiddick Island ended in a horrible tragedy that haunts me every day of my life."
