The Trump administration has filed a lawsuit against California's law banning federal agents from wearing masks during operations, citing safety concerns for officers. This legal action highlights tensions between state and federal law enforcement practices.

On November 17, 2025, the Trump administration filed a lawsuit against California regarding a law that bans federal agents from wearing masks during official duties. This law, signed by Governor Gavin Newsom, aims to increase transparency by requiring law enforcement officers to display clear identification. The federal government contends that the law jeopardizes the safety of officers, who face significant threats and harassment. The lawsuit cites incidents where Immigration and Customs Enforcement (ICE) agents were followed home and their personal information shared online. Critics of the law argue it is necessary for public safety, while supporters claim it discriminates against federal agents. The federal government also argues that the law violates the Supremacy Clause of the Constitution, which limits state regulation of federal entities. California's Attorney General is currently reviewing the lawsuit.
