COINTELPRO (1956–1971)
The FBI ran a covert program of surveillance, infiltration, and harassment targeting civil rights, anti-war, and other political groups it deemed subversive. Agents labeled legitimate activists as threats and used informants, wiretaps, and smear campaigns against them.
The 1975 Church Committee hearings exposed the program and forced the FBI to adopt domestic security guidelines limiting surveillance of political activity.
The program became the defining example of federal surveillance of lawful political activity, shaping decades of First Amendment jurisprudence.
The Common Cause suit makes a similar argument: that the federal government has labeled lawful observers as 'domestic terrorists' and used surveillance tools to punish them for exercising protected speech.
