The Act was passed on the last day before Congress adjourned for the 2006 elections. Though a bill with the gambling wording was previously debated and passed by the House of Representatives,[6][7][8] the SAFE Port Act (H.R. 4954) as passed by the House on May 4th (by a vote of 421-2) and the United States Senate on September 14th (98-0),[9] bore no traces of the Unlawful Internet Gambling and Enforcement Act that was included in the SAFE Port Act signed into law by George W. Bush on October 13th, 2006.[10] The UIGEA was added in Conference Report 109-711 (submitted at 9:29pm on September 29, 2006), which was passed by the House of Representatives by a vote of 409-2 and by the Senate by unanimous consent on September 30, 2006. Due to H.RES.1064, the reading of this conference report was waived.
Among the more prominent Congressional supporters of the Act were Jim Leach, a former chairman of the House Banking Committee and Rep. Robert Goodlatte [R-VA], who co-authored H.R. 4411 (the Internet Gambling Prohibition and Enforcement Act). Bill Frist, former majority leader of the Senate, and Jon Kyl are both credited with expediting the UIGEA's passage through the Senate. Though the SAFE Port Act's provisions related to Internet gambling were drawn exclusively from H.R. 4411, significant portions were removed, including text relating to the Federal Wire Act.[11]

At least our ports are safe now.....
