Matters relating to internal US security.

Joseph Burkholder Smith, Portrait of a Cold Warrior (Ballantine Books, New York, 1976), p. 387

Smith, a CIA officer for 22 years, wrote: "CIA cryptonyms use a digraph, two letters at the beginning of a word, to help process the material the cryptonym covers. Sometimes the digraph indicates a geographic location, other times general subject matter. MH stood for matters relating to internal US security."

Verne Lyon, "Domestic Surveillance: The History of Operation CHAOS", Covert Action Information Bulletin, Summer 1990.

In 1965, President Lyndon Johnson requested that the CIA begin its own investigation into domestic dissent—independent of the FBI's ongoing COINTELPRO. In 1968, the CIA printed a 199-page study entitled "Restless Youth" on worldwide student dissidence.

Angus McKenzie, Secrets,

MHCHAOS was run by Richard Ober, a counterintelligence specialist who reported to James Angleton. Angleton chose Ober for the job. Ober set up the Special Operations Group for this program."
