The CLEAN Act would convert the Office of Congressional Ethics from a temporary institution into permanent law. Currently, the Office operates under House Resolution 895 from the 110th Congress, but this bill would make its structure and authority lasting. The legislation establishes specific rules for the office's board, including limiting members to serve no more than four two-year terms, requiring any board vacancies to be filled within 60 days, and ensuring that individuals under review have the right to legal representation without facing negative consequences for exercising that right. The bill also clarifies that the Office operates as a standing committee of the House and that the separate Committee on Ethics will handle referrals from the Office. This bill would primarily affect House members and staff by providing a permanent ethics oversight body, though it does not allocate specific funding amounts or establish particular timelines beyond the 60-day vacancy-filling requirement.
