After the Bay of Pigs disaster President John F. Kennedy created a committee (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.

The CIA JM/WAVE station in Miami served as operational headquarters for Operation Mongoose. The head of the station was Ted Shackley and over the next few months became very involved in the attempt to overthrow Fidel Castro. One of Lansdale's first decisions was to appoint William Harvey as head of Task Force W. Harvey's brief was to organize a broad range of activities that would help to bring down Castro's government.
