Three whistleblowers – all former employees of the National Security Agency (NSA) – have come forward to give evidence in the Electronic Frontier Foundation’s (EFF’s) lawsuit against the government’s illegal mass surveillance program, Jewel v. NSA.

In a motion filed today, the three former intelligence analysts confirm that the NSA has, or is in the process of obtaining, the capability to seize and store most electronic communications passing through its U.S. intercept centers, such as the “secret room” at the AT&T facility in San Francisco first disclosed by retired AT&T technician Mark Klein in early 2006.
