This legislation mandates that states reimburse the federal government for expenses related to the deployment of federal military personnel, including members of the National Guard and Selected Reserve. Such deployments must be a direct consequence of civil disturbances or security threats arising from lawful federal immigration enforcement operations. Crucially, the need for deployment must be attributed to a state's or local government's failure to provide reasonable cooperation or coordination with these federal operations. The Secretary of Defense would issue an invoice to the affected state's Governor, covering costs such as temporary duty travel , housing, meals, and transportation for personnel and equipment. The Secretary of Homeland Security, in consultation with the Attorney General, would determine if a state's actions or omissions materially hindered federal immigration enforcement. States would have 180 days to remit payment, and failure to do so could result in the President rescinding discretionary federal grants to offset the unpaid amount.
