To direct the Comptroller General of the United States to submit to Congress an updated report on the roles, responsibilities, and practices of the Council on Environmental Quality.

HR 8156 requires the Government Accountability Office (GAO) to submit to Congress an updated report on the Council on Environmental Quality (CEQ) within 120 days of the bill's enactment. The report must specifically address the CEQ's role in the Lower Snake River dams litigation case, including whether it meets its legal duties under environmental law and whether its functions could be handled by another agency. It also mandates details on the CEQ's use of outside contractors, its reliance on non-governmental organizations, and staff connections to groups involved in environmental cases. This procedural bill directly affects Congress, which will receive the report to inform oversight of the CEQ's operations.
