Department of Homeland Security: Progress Made and Work Remaining in Implementing Homeland Security Missions 10 Years After 9/11, Statement of Gene L. Dodaro Comptroller General of the United States, Testimony Before the Committee on Homeland Security and Governmental Affairs, U.S. Senate [open pdf - 276KB]
"The terrorist attacks of September 11, 2001, led to profound changes in government agendas, policies and structures to confront homeland security threats facing the nation. Most notably, the Department of Homeland Security (DHS) began operations in 2003 with key missions that included preventing terrorist attacks from occurring in the United States, reducing the country's vulnerability to terrorism, and minimizing the damages from any attacks that may occur. DHS is now the third-largest federal department, with more than 200,000 employees and an annual budget of more than $50 billion. Since 2003, GAO [Government Accountability Office] has issued over 1,000 products on DHS's operations in such areas as border and transportation security and emergency management, among others. As requested, this testimony addresses DHS's progress and challenges in implementing its homeland security missions since it began operations, and issues affecting implementation efforts. This testimony is based on a report GAO is issuing today, which assesses DHS's progress in implementing its homeland security functions and work remaining. […] While this testimony contains no new recommendations, GAO previously made about 1,500 recommendations to DHS. The department has addressed about half of them, has efforts underway to address others, and has taken additional action to strengthen its operations. In commenting on GAO's report upon which this testimony is based, DHS stated that the report did not address all of DHS's activities. The report was based on prior work, which GAO reflected throughout the report."
