California has become the first state to prohibit most law enforcement officers, including federal immigration agents, from wearing masks while performing official duties. Governor Gavin Newsom signed the bill into law on Saturday, a move that has drawn criticism from Trump administration officials.

The legislation is a direct response to recent immigration raids in Los Angeles, where federal agents wore masks during mass arrests. These operations sparked protests across the city and prompted President Donald Trump to deploy National Guard troops and Marines to the area. Newsom stated that the law aims to enhance transparency and accountability in law enforcement, particularly in a state where 27% of residents are foreign-born.

"We celebrate that diversity. It’s what makes California great. It’s what makes America great. It is under assault," Newsom said during a news conference in Los Angeles, surrounded by lawmakers and community leaders. He expressed concerns about masked agents detaining individuals without proper identification, describing the situation as reminiscent of a dystopian film.

The new law bans neck gaiters, ski masks, and other facial coverings for local and federal officers while on duty, with exceptions for undercover agents and medical masks like N95 respirators. It does not apply to state police. However, it remains unclear how the state will enforce this ban against federal agents, who have defended their use of masks as a necessary safety measure amid increasing harassment.

Bill Essayli, acting U.S. attorney for Southern California, stated that the state lacks jurisdiction over federal operations and emphasized that federal agents will continue to protect their identities. He criticized Newsom's comments, suggesting they could be interpreted as threats against government officials.

Homeland Security Assistant Secretary Tricia McLaughlin condemned the law as "despicable," arguing that it endangers officers who face violence while carrying out their duties. She noted that federal agents are already required to identify themselves during operations.

The law is part of a broader effort by California lawmakers to counteract federal immigration policies. Newsom also signed additional legislation that restricts immigration agents from entering schools and healthcare facilities without a valid warrant and mandates that schools notify parents and staff when agents are present.

Supporters of the mask ban argue it is essential for building public trust in law enforcement and preventing impersonation of officers. Constitutional law expert Erwin Chemerinsky defended the legislation, stating that federal employees must adhere to state laws unless it significantly interferes with their duties.

The law will take effect next year, and its implications for federal law enforcement remain uncertain. Other states, including New York and Massachusetts, are considering similar measures. The California law reflects ongoing tensions between state and federal authorities regarding immigration enforcement and law enforcement practices.
