This report formally transmits a briefing in response to Senate Report No.110-77, which accompanied the National Defense Authorization Act for Fiscal Year 2008. The Senate Report directed GAO to review the department's efforts to prevent, identify, investigate, and report Antideficiency Act (ADA) violations and disciplinary actions taken when violations occur. On July 22, 2008, we provided our preliminary observations to staff of Congressional committees in response to the mandate. We will be reporting details on the information presented in the briefing in a future report.
