A letter report issued by the Government Accountability Office with an abstract that begins "In 2004, an estimated 23 billion pounds of air cargo was transported within the United States, about a quarter of which was transported on passenger aircraft. Within the Department of Homeland Security (DHS), the Transportation Security Administration (TSA) is responsible for ensuring the security of commercial aviation, including the transportation of cargo by air. To evaluate the status of TSA's efforts to secure domestic air cargo, GAO examined (1) the extent to which TSA used a risk management approach to guide decisions on securing air cargo, (2) the actions TSA has taken to ensure the security of air cargo and the factors that may limit their effectiveness, and (3) TSA's plans for enhancing air cargo security and the challenges TSA and industry stakeholders face in implementing these plans."

A letter report issued by the Government Accountability Office with an abstract that begins "On January 13, 2004, the Office of the Comptroller of the Currency (OCC) issued two sets of rules (the preemption rules) on the extent to which the National Bank Act preempts the application of state and local laws to national banks and their operating subsidiaries. The rules and the manner in which OCC promulgated them generated considerable controversy. Some state officials, consumer groups, and congressional members questioned whether OCC adhered to the statutes and executive orders pertaining to rulemaking and whether the process was as inclusive as it could have been. GAO (1) assessed OCC's rulemaking process within the framework of applicable laws and executive orders, (2) described the issues raised in comment letters and OCC's responses, and (3) identified and discussed stakeholder concerns about how OCC promulgated its preemption rules."
