What did the CIA's CHAOS program gather on named Americans, and how many files?

Research question: What did the CIA's CHAOS program collect on named American citizens, and how many files did it open?

The records show that Operation CHAOS held files on about 7,200 Americans at its end, along with a computer index of 300,000 civilians and about 1,000 groups ¹. The Church Senate subcommittee's 1976 final report put the count at more than 7,000 American citizens and 1,000 domestic organizations ⁶. The facts do not identify specific named individuals or describe the contents of individual files, though the program's stated purpose was to record the organizing, groups, and individuals that CIA assets came into contact with ⁷. The information gathered was disseminated in thousands of reports to the FBI and other agencies ⁸. The newest fact provided comes from a 1985 CIA Reading Room document, so the evidence is about four decades old as of October 2026 ².
