Executive Branch Conflict of Interest Prevention Act of 2023

This bill bans senior U.S. government officials (those at GS-15 level or higher, military officers at O-7 or above, or equivalent roles) from holding financial interests in entities that pose conflict risks. Specifically, it prohibits ownership in corporations, businesses, or for-profit entities that are substantially regulated by their agency, major agency contractors, organizations with heavy lobbying ties to the agency, or those creating a realistic appearance of conflict. The Office of Government Ethics must define key terms like "substantially regulated" and "major contractor" through guidance. Agencies must report to Congress if they determine no conflicts exist, detailing their evaluation process and including inspector general assessments where applicable.
