The Foreign Intelligence Surveillance Act of 1978 (FISA) regulates certain types of foreign intelligence collection including certain collection that occurs with compelled assistance from U.S. telecommunications companies. Given the techniques that NSA must employ when conducting NSA's foreign intelligence mission, NSA quite properly relies on FISA authorizations to acquire significant foreign intelligence information and will work with the FBI and other agencies to connect the dots between foreign-based actors and their activities in the U.S. The FISA Court plays an important role in helping to ensure that signals intelligence collection governed by FISA is conducted in conformity with the requirements of the statute. All three branches of the U.S. Government have responsibilities for programs conducted under FISA, and a key role of the FISA Court is to ensure that activities conducted pursuant to FISA authorizations are consistent with the statute, as well as the U.S. Constitution, including the Fourth Amendment.
