Justice Department Sues Maryland Over Sanctuary Immigration Policies

The United States Department of Justice filed a federal lawsuit on July 9, 2026, against the state of Maryland and Attorney General Anthony Brown. The suit challenges the Community Trust Act, enacted in May 2026, which restricts local law enforcement from sharing information with U.S. Immigration and Customs Enforcement or holding individuals without a judicial warrant, except in cases involving sex offenses or felonies.

Federal prosecutors argue that the act violates the Supremacy Clause of the U.S. Constitution and thwarts the president's obligation to enforce federal immigration laws. This action is part of a broader campaign by the DOJ's Civil Division, which has now targeted 21 jurisdictions, including Colorado, Connecticut, Illinois, and New York. The DOJ claims these sanctuary policies jeopardize public safety by releasing dangerous criminals.

Maryland officials and Governor Wes Moore's office defended the law, stating it protects civil rights and maintains community trust while still allowing coordination regarding violent offenders. However, the state faces simultaneous legal pressure from within, as 17 of Maryland's 24 sheriffs filed a separate lawsuit claiming the act interferes with their ability to coordinate with federal authorities on public safety threats. Republican lawmakers in the state have characterized the sanctuary approach as a danger to security that invited federal litigation.
