State Accountability for Federal Deployment Costs Act of 2025

This bill requires states and local governments to reimburse the federal government for costs when they obstruct lawful federal immigration enforcement, leading to military deployments. Specifically, if a state fails to cooperate with immigration operations (like refusing detainer requests), the Secretary of Defense must send the state a bill for expenses like military personnel travel, lodging, and equipment transport. States have 180 days to pay the invoice, or the President may withhold federal grants to offset the unpaid amount. The bill targets reimbursement for deployments triggered by state noncooperation, not for routine enforcement. It does not change immigration law but shifts costs to jurisdictions that impede federal operations.
