nsa spying on u.s. citizens was first reported in 1975..,

foreignpolicy | As Vietnam War protests grew, the U.S. National Security Agency (NSA) tapped the overseas communications of prominent American critics of the war -- including a pair of sitting U.S. senators. That's according to a recently declassified NSA history, which called the effort "disreputable if not outright illegal."

For years the names of the surveillance targets were kept secret. But after a decision by the Interagency Security Classification Appeals Panel, in response to an appeal by the National Security Archive at George Washington University, the NSA has declassified them for the first time. The names of the NSA's targets are eye-popping. Civil rights leaders Martin Luther King and Whitney Young were on the watch list, as were the boxer Muhammad Ali, New York Times journalist Tom Wicker, and veteran Washington Post humor columnist Art Buchwald. But perhaps the most startling fact in the declassified document is that the NSA was tasked with monitoring the overseas telephone calls and cable traffic of two prominent members of Congress, Sen. Frank Church (D-Idaho) and Sen. Howard Baker (R-Tenn.). As shocking as the recent revelations about the NSA's domestic eavesdropping have been, there has been no evidence so far of today's signal intelligence corps taking a step like this, to monitor the White House's political enemies. 

As the Vietnam War escalated during Lyndon B. Johnson's presidency, domestic criticism and protest movements abounded. Protesters surrounded the Pentagon in the fall of 1967 and two years later organized demonstrations and the Moratorium to End the War in Vietnam. The scale of the dissent angered Johnson as well as his successor, Richard Nixon. As fervent anti-communists, they wondered whether domestic protests were linked to hostile foreign powers, and they wanted answers from the intelligence community. The CIA responded with Operation Chaos, while the NSA worked with other intelligence agencies to compile watch lists of prominent anti-war critics in order to monitor their overseas communications. By 1969, this program became formally known as "Minaret."

The NSA history does not say when these seven men were placed on the watch list -- or, more importantly, who decided to task the NSA to monitor their communications. But the simple fact that the NSA secretly intercepted the telephone calls and telegrams of these prominent Americans, including two U.S. senators, at the White House's behest is alarming in the extreme. It demonstrates just how easily the agency's vast surveillance powers have been abused in the past and can be abused even today. 

Minaret's notoriety in U.S. intelligence history is well deserved, even if details of the operation have faded from the public's memory over the past 40 years. Minaret and its companion program, Operation Shamrock, were virtual progenitors of the now-notorious warrantless domestic eavesdropping program that George W. Bush's administration ran from 2001 to 2004. Moreover, the 1975 disclosure of the programs' existence by the Church Committee, chaired by a Minaret target himself, Sen. Frank Church, was one of the principal reasons that Congress passed the Foreign Intelligence Surveillance Act in 1978. An incredibly broad warrant, issued under that act, to monitor the call records of Verizon Business Network Services customers was the first of many documents leaked this year by former NSA contractor Edward Snowden. 

Carried out between 1967 and 1973, the watch list of domestic critics had its origins in the paranoia that pervaded the White House during the administrations of Johnson and Nixon, as public discontent over the Vietnam War grew. The idea of the watch list, however, developed before the war in order to monitor narcotics traffickers and possible threats to the president. The NSA watch list began informally in the summer of 1967, prompted by Johnson's belief that the growing number of anti-Vietnam War demonstrations and race riots sweeping the United States were being covertly instigated and sustained by the Soviet Union and its allies. Most names placed on the first NSA watch list came from the FBI and the CIA, which wanted any intelligence concerning foreign governments' involvement with American anti-war and civil rights organizations. In 1969, during Nixon's administration, the watch list became formally known as Minaret.
