“On January 17 [2007], Attorney General [Alberto] Gonzales announced that the warrantless eavesdropping program was coming to an end and the NSA’s [National Security Agency’s] eavesdropping activities from then on would once again come under the FISA [Foreign Intelligence Surveillance Act] court. ‘All surveillance previously occurring under the Terrorist Surveillance Program (TSP) would now be conducted subject to the approval of the FISC [Foreign Intelligence Surveillance Court],’ Gonzales said. ‘Under these circumstances, the President [Bush] had determined not to reauthorize the TSP when the then current authorization expired.’ “
