In 1964, the FBI's COINTELPRO program began attempts to infiltrate and disrupt the Ku Klux Klan.

Jerry Thompson, a newspaper reporter who infiltrated in the Klan in 1979, reported that COINTELPRO's efforts had been highly successful in disrupting the Klan; rival Klan factions both accused each other's leaders of being FBI informants, and one leader, Bill Wilkinson of the Invisible Empire, Knights of the Ku Klux Klan, was in fact later revealed to have been working for the FBI.
