The FBI urged members of the House Judiciary Subcommittee on Crime, Terrorism and Homeland Security on Thursday to update the Communications Assistance to Law Enforcement Act (CALEA) and make it easier for authorities to eavesdrop on Internet.

The act was passed in 1994 and requires telecommunication companies to design their equipment and services to ensure that law enforcement and national security officials can monitor telephone and other communications whenever necessary.

“Over the years, through interpretation of the statute by the Federal Communications Commission, the reach of CALEA has been expanded to include facilities-based broadband internet access and Voice over Internet Protocol (VoIP) services that are fully inter-connected with the public switched telephone network,” FBI General Counsel Valeria Caproni told the subcommittee.
