From the Executive Summary: "In the USA PATRIOT Improvement and Reauthorization Act of 2005 (the Reauthorization Act), Congress directed the Office of the Inspector General (OIG) to conduct ' a comprehensive audit of the effectiveness and use, including improper or illegal use' of the Federal Bureau of Investigation's (FBI) use of Section 215 of the Patriot Act. See Pub. L. No. 109-177, [section]106A. Section 215 of the Patriot Act allows the FBI to seek orders from the Foreign Intelligence Surveillance Court for 'any tangible things,' including books, records, and other items from any business, organization, or entity provided the item or items are for an authorized investigation to protect against international terrorism or clandestine intelligence activities. Congress directed the OIG to review the use of Section 215 for two time periods-calendar years (CY) 2002 through 2004 and CY 2005 through 2006. The first report is due to Congress on March 9, 2007; the second is due on December 31, 2007."
