The "Federal Agency Sunset Commission Act of 2025" establishes a commission to review the efficiency and public need for federal agencies, potentially leading to their abolishment unless Congress reauthorizes them. The commission will submit recommendations to Congress, which will then vote on whether to abolish, reorganize, or continue each agency. This act aims to increase government accountability and efficiency by regularly evaluating the necessity and performance of federal agencies. The bill also creates a program inventory to help with the review process.
