The Foreign Intelligence Surveillance Court (FISC) has declassified an order about the Department of Justice's handling of 2016 and 2016 applications for Foreign Intelligence Surveillance Act (FISA) warrant for Trump campaign associate Carter Page. The Dec. 2019 Office of Inspector General (OIG) Report about the FBI's investigation into Russian interference in the 2016 election devoted considerable discussion to the Page warrants.
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.
