In a 1971 interview with Ramparts, former U.S. Air Force and NSA analyst Perry Fellwock—using the pseudonym Winslow Peck—publicly described the NSA as a vast, highly secretive organization operating a worldwide signals-intelligence network. Fellwock said the agency’s budget was larger than the CIA’s, although the source provides no precise figure. His account helped bring public attention to ECHELON, the name later used for a Five Eyes interception and analysis system originally associated with monitoring Soviet and Eastern Bloc communications during the Cold War.
Fellwock was inspired by Daniel Ellsberg’s release of the Pentagon Papers. His disclosure contributed to congressional scrutiny of intelligence abuses, including the Church Committee’s investigations chaired by Senator Frank Church. Congress passed legislation in 1973 aimed at restricting improper domestic surveillance, and the investigations helped lead to the Foreign Intelligence Surveillance Act of 1978, which established procedures for electronic and physical surveillance involving foreign powers and their agents. After the September 11, 2001 attacks, FISA was amended under President George W. Bush to expand warrantless surveillance authority, preserving the legal and political consequences of the secrecy Fellwock helped challenge.
