This bill establishes the Detention and Logistics Program within the Department of Homeland Security, designed to reimburse states and local governments for expenses incurred in detaining migrants at facilities within their jurisdictions. This reimbursement covers costs incurred on or after January 20, 2025, and requires an application process for eligible entities. To fund this program, the bill mandates the transfer of all unobligated balances from the Federal Emergency Management Agency's Shelter and Services Program to appropriate DHS accounts. Furthermore, it requires the Secretary of Homeland Security to submit a report within 90 days, detailing a plan for coordinating with states to rapidly construct new migrant detention facilities and identifying suitable federal or state properties. The report must also identify underutilized federal accounts whose funding could be better utilized by the Detention and Logistics Program.
