Sept. 26, 1961 - President Kennedy is expected to name John A. McCone (right) tomorrow as director of the Central Intelligence Agency. Mr. McCone, a Republican businessman, served as chairman of the Atomic Energy Commission during the Eisenhower Administration. He would succeed Allen W. Dulles (center), the present director, who is expected to resign. Mr. Dulles has been head of the agency since 1953. Pressures for his retirement arose after the abortive rebel invasion of Cuba last spring. There has been considerable criticism of the CIA's handling of preparations for the invasion. The functions and organization of the Agency have been under study by the Kennedy Administration since the Cuban affair.
