The legislation adds a new subsection to Section 3056 of title 18, formalizing the process for federal compensation to state and local entities for their support. A key provision includes retroactive application , permitting reimbursement for eligible utilization that occurred between July 12, 2024, and the effective date of this Act. This measure aims to ensure that state and local governments are compensated for their contributions to national security and presidential protection efforts.
