Published every year since 2014, the ASTR provides the public with statistics and contextual information regarding the scope of the government’s use of FISA authorities, National Security Letters, and other national security authorities. In conjunction with other publicly released material, this report adds insight into the rigorous and multi-layered oversight framework governing the IC that is designed to protect the privacy and civil liberties of persons whose information is acquired pursuant to these national security authorities.
