"In June 2013, President Obama directed the Intelligence Community (IC) to declassify and make public as much information as possible about certain sensitive U.S. government surveillance programs while protecting sensitive classified intelligence and national security information. Since then, the Director of National Intelligence (DNI) has declassified and authorized the public release of thousands of pages of documents relating to the use of critical national security authorities, including the Foreign Intelligence Surveillance Act (FISA). In addition to declassifying and publicly releasing these documents, the Intelligence Community has published several reports regarding these authorities, including the 'Statistical Transparency Report Regarding use of National Security Authorities' (hereafter the DNI's annual transparency report), presenting metrics related to the use of certain authorities for calendar years 2013 and 2014. [...] Today, consistent with the USA FREEDOM Act and the IC's 'Principles of Intelligence Transparency', we are releasing our third annual transparency report presenting statistics on how often the government uses certain national security authorities. The DNI has declassified and directed the release of the applicable statistics covering calendar year 2015."
