Congressional Budget Office Cost Estimate: H.R. 5825: Electronic Surveillance Modernization Act [open pdf - 17KB]
"H.R. 5825 would modify the rules and procedures the government must follow to use electronic surveillance programs in the investigation of international terrorism. The bill would amend the definition of electronic surveillance under the Foreign Intelligence Surveillance Act (FISA) to remove the current distinction between treatment of wire and radio communications, and to focus FISA protections on domestic communications. The bill also would expand the ability of the government to conduct electronic surveillance without a warrant in certain cases where the target of the surveillance is an agent of a foreign power."
