"The president wanted someone that he could trust, so he formed his own small group of operatives which he called “Pegasus.”"

"[Tatum] believes Pegasus was established during the Eisenhower years as a secret group inside the CIA to spy on that agency on behalf of the President."

"The directors of Pegasus meet once a year in secret conclave following G7 meetings. The group has "representation" from a number of intelligence agencies throughout the world. Included are the US Drug Enforcement Administration (DEA), the Central Intelligence Agency (CIA), the Bureau of Alcohol, Tobacco and Firearms (ATF) as well as agents from British, Israeli, Turkish and Danish Intelligence plus "others who performed various functions for Pegasus".7 The mission of Pegasus, Tatum explains, is "to 'align' world leaders and financiers to our [US] policies and standards"."
