From Kirk's Website:
In addition to H.R. 4437, Congressman Kirk voted in favor of several narrowly focused immigration reform bills that the House passed in September of 2006. To address concerns regarding border tunnels that provide illegal pathways into the United States, the House passed H.R. 4830, The Border Tunnel Prevention Act, which strengthens penalties for individuals caught using or constructing a tunnel into the country. The House also passed H.R. 6094, The Community Protection Act of 2006, which gives the Department of Homeland Security the authority to detain dangerous aliens beyond six months, rather than requiring that they be released into society. H.R. 6094 also renders alien gang members, such as members of MS-13, deportable. In addition, the House passed H.R. 6061 The Secure Fence Act, which provides for over 700 miles of two-layered reinforced fencing along the southwest border with prioritized placement at critical, highly populated areas.
