Congresswoman Bella Abzug had issues with trusting CIA when it came to their handling evidence of illegal and improper Agency activities. These issues had been previously raised with then-CIA Director George H.W. Bush, prompting some behind-the-scenes waffling at CIA over whether they would promise to obey the law when it came to destroying records of CIA wrongdoing. By no means was the question settled, as CIA memos show that they continued to debate how to handle the destruction of records. While the Congresswoman fought to prevent the destruction of records of CIA wrongdoing, the Agency rushed to begin destroying everything they could.

Operation MKULTRA was an umbrella for a series of CIA experiments with drugs, hypnosis, sleep deprivation, sensory deprivation, electroshocks, and other forms of torture on uninformed Americans and Canadians in an effort to discover the ideal truth serum, manipulate memories, and modify behaviors.

A little known, but extremely important, part of the history of COINTELPRO and abuses of the intelligence agencies is the CACTUS cryptonym/program. CACTUS was a highly classified channel used by CIA and FBI to transmit information about “the New Left, Black Militants and related matters.” This channel was never disclosed in the Church Committee reports, even when the reports discuss information that was transmitted through the CACTUS channel. A review of the available documents also indicates that the program is older than previous FOIA releases might indicate.

According to a memo released to several researchers, the CACTUS indicator was described for FBI Director Hoover by CIA Director Helms on April 22, 1970. The conclusion by the very few resources to mention the program has been that the program was first introduced on this date.
