The Keep ICE Out of Washington County, Maryland Act would prohibit the Department of Homeland Security and U.S. Immigration and Customs Enforcement from establishing, operating, expanding, or reopening any immigration detention or holding facility in Washington County, Maryland. The bill would also ban the use of any federal funds for these purposes in the county. The legislation applies to facilities operated directly by the government or run through contracts with private companies and other entities. To enforce the ban, the bill grants standing to sue in federal court to Washington County residents, local government, Maryland state officials, and Members of Congress, allowing them to seek court orders blocking any violations. Congress justified the prohibition by citing community concerns about detention facilities' impacts on public health, housing, and local services, as well as documented problems with conditions and due process in immigration detention facilities nationwide.
