A letter report issued by the Government Accountability Office with an abstract that begins "Terrorist groups need significant amounts of money to organize, recruit, train, and equip adherents. U.S. disruption of terrorist financing can raise the costs and risks and impede their success. This report (1) provides an overview of U.S. government efforts to combat terrorist financing abroad and (2) examines U.S. government efforts to coordinate training and technical assistance. We also examined specific accountability issues the Department of the Treasury faces in its efforts to block terrorists' assets held under U.S. jurisdiction."
