"The committee has queried David Ronis, the author of the above cited dispatch requesting that Calderon's sister be contacted by the CIA's 'domestic exploitation section.' (HSCA Class. Staff interview of David Ronis, 8/31/78). Ronis was a member of the CIA's Special Affairs Staff at the time he wrote the dispatch. He worked principally at CIA headquarters and was responsible for recruitment and handling of agents for collection of intelligence data. Mr. Ronis, when interviewed by this Committee, stated that part of his responsibility was to scour the Western Hemisphere Division for operational leads related to the work of the Special Affairs Staff. Ronis recalled that he normally would send requests to CIA field stations for information or leads on various persons. Often he would receive no response to these requests, which normally indicated that no follow-up had either been attempted or successfully conducted. It was Ronis' recollection that the above-cited domestic exploitation section was a task force within the Special Affairs Staff. He also stated that in 1963 the CIA's Domestic Contacts Division might have been requested to locate Luisa Calderon's sister. Ronis told the Committee that he had no recollection of recruiting any person associated with the Cuban Intelligence Service. He did recall that he had recruited women to perform tasks for the Agency. However, he did not recall ever recruiting any employees of the Cuban Embassy/Consulate in Mexico City. Finally, Mr. Ronis stated that he had no recollection that Luisa Calderon was associated with the CIA..."
