On Sept. 18th, the San Francisco-based Electronic Frontier Foundation filed a lawsuit in federal court against the NSA on behalf of five AT&T customers to stop the ongoing surveillance of their telephone and internet communications. The plaintiffs are also suing the President, Vice President and other officials who ordered or participated in the warrantless wiretapping.

Evidence in the case includes documents provided by former AT&T technician Mark Klein showing AT&T routed copies of internet traffic to a secret room in San Francisco controlled by the NSA.

This latest lawsuit filed by civil liberties groups fighting the domestic spying program established shortly after Sept. 11th, 2001, follows on the heels of Congress' attempt to provide "retroactive immunity" to the telecommunications companies participating in the program through the FISA Amendments Act of 2008.
