What do CIA papers show about midnight file searches and spying on reporters?

Research question: What do CIA Office of Security records and internal correspondence show about the midnight file-rifling and newsmen surveillance, and where are those records held today?

The verified facts do not directly describe CIA Office of Security records or internal correspondence about midnight file-rifling or surveillance of newsmen. They only name domestic programs such as HTLINGUAL, CHAOS, MERRIMAC, and RESISTANCE that a 2016 dissertation examines 3, and that author concludes the NSA, FBI, and CIA knowingly and repeatedly violated the constitutional rights of countless citizens between World War II and the Vietnam War 5. On location, most CIA records stay with the agency longer than most agencies keep theirs 2, and Historical Collections documents are reviewed with CIA components before transfer to the National Archives 1. Selected topical copies are deposited at the National Archives, usually redacted 4, and CREST declassified records, once available only in College Park, Maryland, have been online through the Electronic Reading Room since January 17, 2017 67. The newest fact is from January 2017, so it is about nine years old as of October 2026 and may not reflect current holdings.
