This legislation aims to hold states financially responsible for federal military deployments, requiring them to reimburse the Federal Government for costs when federal military personnel , including the National Guard, are deployed due to civil disturbances or security threats . These deployments must stem directly from a state's refusal to cooperate with lawful federal immigration enforcement operations. The Secretary of Defense would issue an invoice to the affected state's Governor for covered costs, which encompass temporary duty travel, housing, meals, and transportation for deployed personnel and equipment. The Secretary of Homeland Security, in consultation with the Attorney General, would publicly determine if a state's actions or omissions materially hindered federal immigration enforcement, thereby necessitating the deployment. States would have 180 days to remit full payment for these invoices. Should a state fail to pay, the President is authorized to rescind discretionary federal grants awarded to that state to offset the outstanding debt, ensuring accountability for non-cooperation.
