Schiff has been a prominent supporter of surveillance reforms, especially in the wake of the leaks of classified intelligence by Edward Snowden. In 2007, in response to disclosure of the Terrorist Surveillance Program, Schiff and Rep. Jeff Flake offered a successful amendment in the House of Representatives to clarify that the Foreign Intelligence Surveillance Act is the exclusive means for collecting foreign intelligence information within the United States. Schiff has been a critic of the bulk collection of telephone metadata by the National Security Agency. In January 2014, Schiff introduced the Telephone Metadata Reform Act, which would prohibit the bulk collection of domestic phone records. Schiff has also introduced several bills aimed at reforming the Foreign Intelligence Surveillance Court, including a bill to require outside counsel to be appointed to argue for privacy and civil liberties protections in certain cases before the Court.
