Central Intelligence Agency
Audio countermeasures support to the Secret Service
Active: 1960 to 1973
Editorial summary
CIA Technical Services Staff had spent two decades building expertise in covert audio devices: bugs, taps, and the equipment to plant and remove them. Through the 1960s and into the early 1970s, the agency loaned that expertise to the Secret Service, which protects the president and other senior officials.
Before presidential and vice-presidential trips abroad, CIA technicians would sweep hotel rooms, meeting halls, and motorcade routes for hidden listening devices. The Family Jewels memorandum, compiled in 1973, treats this support as ongoing and routine. Item number seven on Howard Osborn's catalogue of admissions lists "Audio Countermeasures Support to the United States Secret Service."
The work was technically domestic in part. Some of the sweeps took place inside the United States, including at advance sites for the President's domestic travel. The 1947 National Security Act prohibits the CIA from conducting internal security functions on American soil. Osborn included the program on his list because he expected congressional investigators might consider domestic sweeps a violation of that charter, even when the purpose was protecting the president.
The Church Committee, in its 1975 report, treated CIA support to the Secret Service as a less serious example of charter ambiguity. The committee found no evidence the agency had used the access to do anything beyond what the Secret Service requested. But the support relationship was a clear example of how the wall between foreign intelligence and domestic law-enforcement work, which the 1947 law tried to build, had become porous in practice.
The Rockefeller Commission described the activity as proper in intent but irregular in legal posture. The Family Jewels acknowledgment was the first time the agency itself put its participation in writing.
