Biography[]

Donovan in 1971
John Donovan graduated from Princeton University in New Jersey in 1953, and he was recruited into the Central Intelligence Agency shortly afterwards. Donovan was sent to Vietnam to coordinate operations against the Viet Cong and North Vietnamese Army, and he befriended special forces soldier Lincoln Clay while fighting alongside him in the Vietnam War in April 1966. In 1968, Donovan decided to work with Clay against the Marcano crime family in New Orleans, Louisiana, providing him with government technology, information, and informants that could help him with his war against the American Mafia; Donovan helped him out due to the Marcano family's involvement in the John F. Kennedy assassination, and he made it his job to hunt down the Kennedy assassins. He left the CIA in 1969 as a result of his operations, and he would be called to testify before a senate committee in 1971. Donovan was interviewed by Senator Richard Blake and several other senators, and he told them all about his role in assisting Clay with his operations. At the end, he confronted Blake about the Kennedy assassination before shooting him dead with a silenced pistol in front of the camera and the other senators, saying that he was just starting his crusade against the JFK conspirators.
