This bill, known as the "Stop MUSK Act," amends title 18 of the United States Code to expand recusal requirements for specific executive branch officers and employees. It applies to individuals in positions listed under the Executive Schedule, special Government employees, and officers or employees of the Executive Office of the President. The core provision requires these officials to recuse themselves from any matter impacting the financial interests of an organization for which they previously served in various capacities, including as an officer, employee, agent, consultant, contractor, or direct competitor , during the 4-year period preceding their government participation. Additionally, recusal is required for organizations in which the official is an active participant, excluding political organizations.
