(KTLA) California Gov. Gavin Newsom signed five bills Saturday designed to push back against the Trump administration’s immigration enforcement policies, a package of legislation he described as a defense of the state’s values of diversity and inclusion.

“There’s a word you’ve never heard uttered from the President of the United States’ lips, certainly not Stephen Miller,” Newsom said during the signing ceremony in downtown Los Angeles. “That’s pluralism. We practice pluralism. It’s a deep point of pride. Those values are under assault.”

According to Newsom’s office, the bills were drafted in response to federal immigration crackdowns launched after President Trump took office and were accelerated after the administration backed aggressive ICE operations.

Several of the new laws focus on public schools. One requires staff to notify students and parents when Immigration and Customs Enforcement (ICE) agents are confirmed to be on campus. Another prohibits federal officers from entering a school without a judicial warrant and blocks schools from sharing students’ personal information.

Other measures extend protections beyond schools. One law requires federal agents, who may not be wearing official uniforms, to display some form of badge or identification. Another, set to take effect in January, bans local, state and federal law enforcement officers from wearing masks while on duty.

Los Angeles Mayor Karen Bass called the legislative package a necessary safeguard. “All of this legislative resistance is to protect Angelenos from our own federal government,” Bass said at the event.

Federal officials immediately pushed back. Acting U.S. Attorney Bill Essayli said in a statement that “the State of California has no jurisdiction over the federal government,” adding, “If Newsom wants to regulate our agents, he must go through Congress. I’ve directed our federal agencies that the law signed today has no effect on our operations. Our agents will continue to protect their identities.”

A Department of Homeland Security spokesperson, Tricia McLaughlin, echoed that criticism, saying in a separate statement that “sanctuary politicians are trying to outlaw officers wearing masks to protect themselves from being doxed and targeted by known and suspected terrorist sympathizers.”

The political fight is not limited to Washington. The Save America movement announced Saturday that it is launching mobile “Liberty” vans staffed with trained professionals to document and film ICE raids across California.

Supporters of the legislation framed the measures as a reaffirmation of California’s role as a counterweight to federal policy. “Because America’s promise of opportunity, dignity and justice must not be surrendered to fear and hate,” said California State Assemblymember Fabian Nuñez.

Most of the new laws take effect immediately, except for the mask ban, which will begin in January.
