The main purpose of this legislation is to create a grant program within the Department of Homeland Security (DHS) that will reimburse states for the costs associated with detaining migrants in their facilities. This program is intended to support states and local governments in managing the financial burden of migrant detention. Key provisions of the legislation include the establishment of the "Detention and Logistics Program," which allows states and local governments to apply for reimbursement of their costs related to migrant detention starting from January 20, 2025.
