The Clinton Administration Backed "No-Warrant Spy Searches" as an "Inherent Authority" of the President

National Review' s Byron York explains here.

In a little-remembered debate from 1994, the Clinton administration argued that the president has "inherent authority" to order physical searches - including break-ins at the homes of U.S. citizens - for foreign intelligence purposes without any warrant or permission from any outside body. Even after the administration ultimately agreed with Congress's decision to place the authority to pre-approve such searches in the Foreign Intelligence Surveillance Act (FISA) court, President Clinton still maintained that he had sufficient authority to order such searches on his own.
