In March I960, President Dwight Eisenhower of the United States approved a Central Intelligence Agency (CIA) plan to overthrow Fidel Castro. The plan involved a budget of $13 million to train "a paramilitary force outside Cuba for guerrilla action." The strategy was organised by Richard Bissell and Richard Helms.

In September 1960, Allen W. Dulles, the director of the CIA, initiated talks with two leading figures of the Mafia, Johnny Roselli and Sam Giancana. Later, other crime bosses such as Carlos Marcello, Santos Trafficante and Meyer Lansky became involved in this plot against Castro.

After the Bay of Pigs disaster President John F. Kennedy created a committee called Special Group Augmented (SGA) charged with overthrowing Castro's government. The SGA, chaired by Robert F. Kennedy (Attorney General), included John McCone (CIA Director), McGeorge Bundy (National Security Adviser), Alexis Johnson (State Department), Roswell Gilpatric (Defence Department), General Lyman Lemnitzer (Joint Chiefs of Staff) and General Maxwell Taylor. Although not officially members, Dean Rusk (Secretary of State) and Robert S. McNamara (Secretary of Defence) also attending meetings.

At a meeting of this committee at the White House on 4th November, 1961, it was decided to call this covert action program for sabotage and subversion against Cuba, Operation Mongoose. Attorney General Robert F. Kennedy also decided that General Edward Lansdale (Staff Member of the President's Committee on Military Assistance) should be placed in charge of the operation.
