The Justice Department's National Security Division released a review of 29 applications for Foreign Intelligence Surveillance Act (FISA) warrants. The 29 applications had been previously examined by the Justice Department's Office of Inspector General (OIG), which shared its findings in a March report.
First passed in 1978, the Foreign Intelligence Surveillance Act (FISA) still guides the physical and electronic surveillance of foreign powers and agents. Congress has repeatedly amended the law, however, seeking to calibrate the government’s surveillance to accord with the level of threat and seeking to keep authorities current as technology develops at breakneck speed. Nevertheless, even authorized activities affirmatively permitted by statute have come under fire as a torrent of leaks have revealed government surveillance programs under the statute.
