Secret NSA project gathered American cellphone location data

The NSA's been rather busy over the past few years, tracking everything from your emails to phone calls, and now the New York Times is reporting that it even conducted a secret project to collect data about the location of American's cellphones in 2010 and 2011. The project was ultimately not implemented and only recently surfaced in a pre-written answer for the director of national intelligence, James R. Clapper, should the subject come up in a Senate Judiciary Committee hearing. According to the Times, details about the project are scarce, and Senator Ron Wyden said that "the real story" behind the project has yet to be declassified. The answer obtained by the paper reads:

"In 2010 and 2011 N.S.A. received samples in order to test the ability of its systems to handle the data format, but that data was not used for any other purpose and was never available for intelligence analysis purposes."
