On July 18, 2006, U.S. Representative Heather Wilson (R-NM) introduced the Electronic Surveillance Modernization Act (). Wilson's bill would give the President the authority to authorize electronic surveillance of international phone calls and e-mail linked specifically to identified terrorist groups immediately following or in anticipation of an armed or terrorist attack on the United States. Surveillance beyond the initial authorized period would require a FISA warrant or a presidential certification to Congress. On September 28, 2006, the House of Representatives passed Wilson's bill and it was referred to the Senate.
