The Stop MUSK Act would require federal executive branch officials and employees to recuse themselves from matters that could financially benefit their previous employers for four years after leaving those companies. The bill amends existing federal ethics law to expand the types of conflicts of interest that trigger mandatory recusal, adding former employers and competitors to the list of organizations from which officials must step aside. This legislation affects all executive branch workers, including cabinet secretaries, agency heads, and lower-level employees who move between government and private sector roles. The bill does not specify any funding requirements or implementation timeline beyond the four-year lookback period for former employment relationships. The measure was referred to the Senate Judiciary Committee in July 2026 for consideration.
