In collaboration with the Committee on House Administration, the OIG continues to do its part to contribute to a more effective and efficient House support structure by identifying and helping mitigate significant risks to the House; highlighting opportunities for improving the efficiency of House operations; and serving as a constructive critic, helpful advisor, and positive change agent.
