Operation CHAOS
The CIA's domestic spying program (1967–1974) that illegally surveilled thousands of American citizens and groups opposed to the Vietnam War.
INVESTIGATION OVERVIEW
Operation CHAOS was a CIA domestic surveillance program that ran from 1967 to 1974 under Director Richard Helms. Despite the CIA's legal prohibition from domestic operations, the program spied on thousands of American citizens and over 1,000 organizations. Targets included anti-war activists, civil rights leaders, and left-wing political groups. The CIA compiled files, opened mail, infiltrated organizations, and coordinated with the NSA for communications intercepts. The program found no evidence of foreign subversion of domestic groups but was nevertheless kept secret until exposed by the Church Committee.
