This legislation aims to terminate the Federal Emergency Management Agency's (FEMA) Shelter and Services Program, which provides support for sheltering activities. Specifically, it prohibits the FEMA Administrator from carrying out any program that supports non-Federal entities in providing sheltering and related services, including facility improvements, intended to relieve overcrowding in U.S. Customs and Border Protection short-term holding facilities. Furthermore, the bill mandates the rescission of all unobligated balances of funds previously made available and transferred to FEMA for these purposes. These funds include amounts from the Consolidated Appropriations Act of 2023 and the Further Consolidated Appropriations Act, 2024, which were originally designated under U.S. Customs and Border Protection's "operations and support" headings.
