This bill restricts how Members of the House of Representatives and Senators can use their official expense funds for motor vehicle purchases or leases. Specifically, funds from the Members' Representational Allowance and Senators' Official Personnel and Office Expense Accounts cannot be used for vehicles that do not meet certain criteria. To be eligible, a motor vehicle must have its final assembly place in the United States. Furthermore, the vehicle must be assembled by employees who are covered by a collective bargaining agreement . These new requirements are set to become effective on October 1, 2026, aiming to promote domestic, unionized manufacturing.
