The main purpose of this legislation, titled the "Pay Our Homeland Defenders Act of 2026," is to ensure that personnel working for the Department of Homeland Security (DHS) continue to receive their salaries and necessary expenses during a government shutdown in the fiscal years 2026 or 2027. This aims to maintain the operational capacity of essential services provided by DHS, particularly during times when funding is not available. Key provisions of the legislation include the appropriation of funds from the U.S. Treasury to cover salaries and allowances for specific groups within DHS.
