From the Summary: "Several sections of the USA PATRIOT Act and one section of the Intelligence Reform and Terrorism Prevention Act of 2004 were originally scheduled to expire on December 31, 2005. In July 2005, both Houses approved USA PATRIOT reauthorization acts, H.R. 3199 and S. 1389, and the conference committee filed a report, H.Rept. 109-333. A separate bill, the USA PATRIOT Act Additional Reauthorizing Amendments Act of 2006 (S. 2271), provided civil liberties safeguards not included in the conference report. Both H.R. 3199 and S. 2271 were signed into law (P.L. 109-177 and P.L. 109-178) by the President on March 9, 2006. This report describes the USA PATRIOT Improvement and Reauthorization Act of 2005 (the Act) and, where appropriate, discusses the modifications to law made by the USA PATRIOT Act Additional Reauthorizing Amendments Act of 2006."
