Meeting at the Agency (a popular location for interagency meetings, because parking was easy on the Langley campus), the four towering figures (Hoover, Helms, Bennett and Gayler – n.n.) in the IC agreed that the legal barrier preventing intelligence collection against protesters inside the United States would need to be lowered.
On June 25, 1970 (…) Huston and the spy leaders convened in Hoover’s downtown office at FBI Headquarters to sign the top-secret (now declassified), forty-three pages ‘Special Report’ that became known in the White House as the Huston Plan. Hoover, Helms, Bennett, and Gayler all signed the document that authorized illegal counterintelligence operations inside the United States. Huston made it clear to President Nixon that some of the proposed intelligence operations involved burglary and were against the law. (…) As historian White has written, the Huston Plan allowed the secret agencies to reach ‘all the way to every mailbox, every college campus, every telephone, every home in America‘. On July 14, the president officially signed the authorization for the plan to be implemented. Huston’s intelligence handiwork in violation of the law was now secret presidential policy.
The plan proved short-lived. When Attorney General John Mitchel – no friend of the antiwar movement – caught wind of the Huston Plan, he persuaded Hoover and the president that the risks of public exposure were too high, potentially having a damaging political effect on the White House and the FBI. Hoover withdrew his support and the president quickly followed suit. (s.n. – M.M.-B.)
