What did Church Committee learn about NSA spying at home, and what proves it?
Research question: What did the Church Committee's NSA surveillance section find about domestic targets, and what primary records support it?
The records show that the Church Committee found the NSA tracked domestic targets through a secret filing system that was destroyed in 1974 2, and that the NSA had conducted wiretaps on targeted U.S. citizens 3. The hearings also revealed that the NSA and GCHQ intercepted the international communications of prominent anti-war leaders, including Jane Fonda and Dr. Benjamin Spock 1. On the cable program, Project Shamrock ran from 1947 until May 1975 13, Senator Church said telegrams mentioning U.S. citizens on a watch list went to NSA analysts 11, and an official said there was little doubt that American citizens' cables were regularly monitored 12, though the article does not say the monitoring targeted domestic persons 10. The supporting primary-type sources are two 1975 CIA Reading Room items 101112, which are press-style reports of the committee's findings; the facts provided do not identify the committee's own report or hearing transcripts.
