More than 2,200 pages of documents were released by the Federal Bureau of Investigation on June 14, 2010. They cover 1961 to 1986 and include scores of death threats, the Chappaquiddick incident that caused the drowning of Mary Jo Kopechne, and investigated rumors about an assassination plot by Sirhan Sirhan and a smear campaign by the mob.
