Correspondence issued by the Government Accountability Office with an abstract that begins "Since the terrorist attacks on September 11, 2001, the Department of Veterans Affairs (VA) has increased its efforts to plan for and respond to national emergencies, including acts of terrorism and natural disasters. Additionally, in August 2004, the Federal Bureau of Investigation and the Department of Homeland Security announced that military and VA medical facilities were potential terrorist targets. In light of military casualties from conflicts in Afghanistan and Iraq and continued threats of terrorist incidents, Congress asked us to review VA's medical support role in emergency preparedness. Specifically, we agreed to provide information on the following questions: (1) What is VA's role in providing medical support within the U.S. to military personnel in wartime and during national emergencies? (2) What actions has VA taken to improve its internal emergency preparedness to ensure that it is ready to maintain continuity of operations and provision of medical services to veterans? (3) What is VA's role in participating in emergency medical response measures with other federal, state, and local agencies?"
