The House Committee on Ethics has the jurisdiction to administer travel, gift, financial disclosure, outside income, and other regulations; advise members and staff; issue advisory opinions and investigate potential ethics violations. The Committee is the only standing committee of the House whose membership is evenly divided between each political party. The Committee includes five members of each party. Also, unlike other committees, the day-to-day work of the Committee on Ethics is conducted by a staff that is nonpartisan by rule. (source)
