Originally CALEA only granted the ability to wiretap digital telephone networks, but in 2004, the United States Department of Justice (DOJ), Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF), Federal Bureau of Investigation (FBI), and Drug Enforcement Administration (DEA) filed a joint petition with the Federal Communications Commission (FCC) to expand their powers to include the ability to monitor VoIP and broadband Internet communications so that they could monitor Web traffic as well as phone calls.
