FISA, the Foreign Intelligence Surveillance Act of 1978, is a very vital part of our arsenal to combat terrorism and espionage. For 20 years, it has enabled the FBI to keep track of major threats to our security while preserving the constitutional rights of Americans. Basically, it provides for a sort of super search warrant, allowing the FBI, under certain unique circumstances, to eavesdrop upon activities, after showing a probable cause to a Federal judge, without having to disclose this eavesdropping in ways that they would have to under a normal warrant for a wiretap or a physical search. FISA has been very useful to deal with terrorism, and also with espionage cases. Senator Specter has undertaken an effort to look into what may or may not have transpired at our National Laboratories in the celebrated case of Wen Ho Lee and others.
