Justice Department Sues Connecticut Over Law Restricting Federal Officers’ Masks, IDs, and Use of Force

Federal officials say state law endangers agents and violates the U.S. Constitution; Connecticut defends measure as a public safety and accountability safeguard

The U.S. Department of Justice has filed a federal lawsuit against Connecticut, challenging a state law that prohibits federal law enforcement officers from wearing facial coverings while on duty, requires them to display badges and name tags, and mandates adherence to state use-of-force policies.

The complaint, filed Friday in U.S. District Court, names Governor Ned Lamont, Attorney General William Tong, and two state prosecutors as defendants. The Justice Department argues that Senate Bill 397, also known as the Act Concerning Democracy and Government Accountability, unconstitutionally attempts to regulate federal officers operating within Connecticut.

“Law enforcement officers risk their lives every day to keep Americans safe, and they do not deserve to be doxed or harassed simply for carrying out their duties,” Acting Attorney General Todd Blanche said in a statement. “Connecticut’s anti-law enforcement policies regulate the federal government and are designed to create risk for our agents. These laws cannot stand.”

The federal government contends that the law violates the Supremacy Clause, which establishes that federal law takes precedence over conflicting state statutes. Justice Department officials said the measure interferes with federal operations, compromises sensitive investigations, and exposes officers to harassment and potential violence by preventing them from protecting their identities.

Associate Attorney General Stanley Woodward framed the lawsuit as a matter of officer safety, noting the timing during national Police Week. “This Department of Justice will not stand by idly in the face of lawless efforts that endanger our brothers and sisters in blue,” Woodward said.

State Law Targets Masked Enforcement

Connecticut passed Senate Bill 397 earlier this year amid growing concerns over federal immigration enforcement tactics. Lawmakers said the measure was designed to prevent voter intimidation and increase law enforcement accountability, particularly following reports of masked federal agents conducting arrests in plainclothes and unmarked vehicles in multiple states.

Among its provisions, the law bars federal officers from wearing facial coverings while performing official duties unless for medical or religious reasons. It also requires officers to clearly display their badge and name tag and to follow Connecticut’s use-of-force policies. Violations can lead to state investigation, prosecution, and penalties of up to 10 years in prison.

State officials have defended the law as a necessary check on federal power, pointing to incidents in which masked agents were accused of using aggressive tactics, including batons, explosives, and firearms, during immigration enforcement actions. Connecticut lawmakers have argued that unidentifiable officers undermine public trust, create safety risks, and impede accountability for misconduct.

In a statement following the law’s passage, state leaders emphasized that the legislation was intended to protect voters from intimidation and ensure that federal operations near polling places are subject to oversight. The measure also requires federal agents to coordinate with Connecticut’s Secretary of State and Attorney General before conducting enforcement near election sites.

Broader Federal Enforcement Push

The Connecticut lawsuit is the latest in a series of legal actions brought by the Justice Department’s Civil Division against states whose policies the federal government says impede lawful federal operations. Similar lawsuits have been filed against New York, New Jersey, and California.

Last year, the Attorney General directed the Civil Division to identify state and local laws that violate federal statutes or obstruct federal law enforcement activities. Officials said Friday’s complaint is part of that ongoing effort.

Assistant Attorney General Brett A. Shumate of the Civil Division said the Connecticut law represents precisely the kind of state interference the Supremacy Clause was designed to prevent. “State interference with federal operations is dangerous and unconstitutional,” Shumate said.

Legal Arguments and Potential Impact

The Justice Department’s complaint alleges that Connecticut’s mask ban, identification requirements, and use-of-force mandates directly conflict with federal law enforcement protocols and operational security needs. Federal officials argue that requiring officers to expose their identities could subject them and their families to retaliation, particularly in cases involving organized crime, gang investigations, or sensitive immigration enforcement.

The federal government also contends that Connecticut cannot impose its own use-of-force standards on federal agents, who are trained and governed by federal policies and laws.

Connecticut has not yet filed a formal response to the lawsuit. Attorney General William Tong’s office declined to comment on pending litigation, though state officials have previously characterized the law as a reasonable public safety measure.

If the court sides with the Justice Department, Connecticut would be barred from enforcing the contested provisions against federal officers. A ruling in favor of the state would represent a significant limit on federal law enforcement authority, potentially allowing other states to adopt similar regulatory measures.

The case is being litigated in U.S. District Court. No hearing date has been set.
