The documents also show the NSA considered tracking targets using cellphone location data, and according to an April 2011 memo consulted the Justice Department first, which said such collection was legal. Only later did the NSA inform the FISA court of the testing.
NSA commander Gen. Keith Alexander revealed the testing earlier this month to Congress but said the agency did not use the capability to track Americans' cellphone locations nor deem it necessary right now.
Asked Monday if the NSA intelligence gathering had been used not only to protect national security but American economic interests as well, White House spokesman Jay Carney said: “We do not use our intelligence capabilities for that purpose. We use it for security purposes.”
Still, he acknowledged the tensions with allies over the eavesdropping disclosures and said the White House was “working to allay those concerns,” though he refused to discuss any specific reports or provide details of internal White House discussions.
