On June 11, 2013, Google asked the government for permission to publish “certain aggregate numbers about its receipt of national security requests,” and a week later petitioned the Foreign Intelligence Surveillance Court with the same request. Yahoo!, Microsoft, LinkedIn, and Facebook also filed similar motions, and Apple filed an amicus brief. After extended negotiation, on January 27, 2014, the Deputy Attorney General issued a letter to the companies, giving them two options for reporting numbers of national security requests (including national security letters). Neither of the options allow providers to definitively state that they have received zero NSLs.
