A letter report issued by the Government Accountability Office with an abstract that begins "The Departments of Defense (DOD) and State (State) and the United States Agency for International Development (USAID) have collectively obligated billions of dollars for contracts and assistance to support U.S. efforts in Afghanistan. There are concerns that U.S. funds are being diverted to fund insurgent and criminal activity in Afghanistan. In light of these concerns, under the authority of the Comptroller General of the United States, we initiated a review to identify DOD, State, and USAID efforts to vet non-U.S. contractors and assistance recipients in Afghanistan. GAO examined (1) the extent to which DOD has established a process to vet non-U.S. vendors to ensure that resources are not used to support insurgents; (2) the extent to which State and USAID have established processes to vet vendors and assistance recipients; and (3) the extent to which vetting information is shared among DOD, State, and USAID. GAO reviewed documents and met with a variety of agency officials to address the report's objectives."
