Three of the country’s largest telecom companies have provided the National Security Agency with the phone call records of tens of millions of Americans. This according to a report in USA Today. One source with direct knowledge of the program called it “the largest database ever assembled in the world” whose goal is to collect a record of “every call ever made” within the United States. The Bush administration has insisted its spy program focuses solely on international calls. The companies — AT&T, Verizon and BellSouth — have been under contract since after the 9/11 attacks. Only one major telecom company declined to participate in the program. The company, Qwest, reportedly asked the NSA to get FISA-court approval before it would hand over the records. The NSA refused. Although the program does not involve the direct monitoring of phone conservations, it amasses detailed records on who people have called and when they’ve called them. At least one company had already been implicated in the program. In a lawsuit filed by the Electronic Frontier Foundation earlier this year, former AT&T technician Mark Klein said AT&T has been working with the National Security Agency to spy on Americans. In addition to raising new questions about the extent of the NSA spy program and the companies involved, the disclosure also raises new questions about CIA Director-nominee Michael Hayden. Hayden headed the National Security Agency at the time the spy program was implemented. He declined USA Today’s request for comment.
