Journalist and historian Burton Hersh has followed the Kennedy family for more than 35 years. His latest book is a study of the behind-the-scenes power struggles among the Kennedys and longtime FBI director J. Edgar Hoover.
Hersh writes that as attorney general, Robert F. Kennedy did his best to keep Hoover — technically his subordinate — on a short leash. But knowledge of Kennedy family secrets gave Hoover, always a master manipulator, the upper hand.
