For this hearing, Walker was asked to: (1) highlight governmentwide issues where it has made a major contribution to oversight and could assist the intelligence and other congressional committees in their oversight of the Intelligence Community; and (2) comment on the potential impact on GAO¿s access to perform audit work on personnel security clearances if the Office of the Dir. of Nat. Intelligence were to assume mgmt. of this issue from the Office of Mgmt. and Budget. Given historical challenges to GAO¿s ability to audit the Intelligence Community¿s programs and activities, this testimony also discusses GAO¿s views on Senate bill S. 82, known as the Intelligence Community Audit Act of 2007.
