Yes. See Pine Gap and John McMahon. But Butterfield's relationship to Moynihan/McMahon goes back further than that, to Bay of Pigs.

"By late 1964, Butterfield was detailed to the policy directorate of war plans in the Office of the Secretary of Defense. There his duties included counterinsurgency planning and management of the program that resettled Cuban veterans of the Bay of Pigs invasion. This latter project Butterfield inherited from his new colleague at the Pentagon: Lt. Col. Alexander Haig."
