NSA Wants to Keep Phone Records Due to Lawsuits Challenging Legality of Surveillance

The National Security Agency needs to keep phone-call metadata longer than the five-year limit in order to preserve evidence for the civil lawsuits challenging the legality of surveillance, the Justice Department said in a court filing Wednesday, The Hill reports. "'The United States must ensure that all potentially relevant evidence is retained,'" government lawyers said, according to The Hill. The government does say the records would be kept for "non-analytical purposes."
