The purpose of the "Troops Before Politicians Act" is to ensure that Members of Congress do not receive their pay if active-duty members of the Armed Forces are not being compensated due to budget issues. This legislation aims to prioritize the financial needs of military personnel over those of lawmakers during times of fiscal uncertainty. Key provisions of the Act include a requirement for the payroll administrators of both the House of Representatives and the Senate to withhold pay for Members of Congress if active service members are not receiving their pay.
