The DOJ Is Done Sending Letters

The Trump administration is suing states and cities. Plural. All at once.

On May 11 and 12, 2026, the Department of Justice filed multiple federal lawsuits against a growing list of jurisdictions — Maine, Massachusetts, Oregon, Washington, New Jersey, New Mexico, and the cities of Albuquerque and New York — for policies the DOJ says deliberately obstruct federal immigration enforcement and endanger federal agents.

The License Plate Fight

One prong of the legal offensive targets a surprisingly specific issue: undercover license plates.

According to Breitbart's reporting on DOJ filings, Maine, Massachusetts, Oregon, and Washington all provide confidential, non-traceable license plates to their own state and local law enforcement — but have refused to extend the same to ICE and DHS agents operating in their jurisdictions.

The DOJ sent warning letters on May 12 to each state demanding they reverse the policy. All four refused. Lawsuits followed the same day.

Deputy Attorney General Todd Blanche said in a statement: "By denying undercover license plates to DHS components, including ICE, while issuing them to their own state agencies, these governors are pursuing discriminatory and obstructionist policies against federal law enforcement."

Assistant Attorney General Brett A. Shumate, who heads the DOJ's Civil Division, spelled out why this matters operationally. In his letter to Washington Attorney General Nick Brown — cited by Breitbart — Shumate noted that federal agents conduct covert operations involving drug trafficking, weapons trafficking, human trafficking, terrorism, and fraud. Identifiable government vehicles blow those operations. They also put agents, their families, and protected witnesses at risk.

The DOJ's position: states that give their own cops undercover plates but deny them to federal agents are making a political choice, not a legal one. That choice has a constitutional problem — the Supremacy Clause.

The Sanctuary Statutes

The second prong hits broader sanctuary policies head-on.

According to VisaHQ's coverage of the New Mexico filing, the DOJ sued on May 11 to block New Mexico's new Immigrant Safety Act — set to take effect May 20 — which bans using state property to detain people for civil immigration violations. The DOJ also sued over Albuquerque's Safer Community Places Ordinance, which restricts ICE cooperation and requires employers to give 24-hour notice to workers when federal agents show up.

Albuquerque Mayor Tim Keller defended the ordinance, arguing it lets immigrants call 911 or send kids to school without fear. But the DOJ's counter is equally straightforward: local governments do not get to nullify federal law because they disagree with it.

Fox News reported a separate DOJ lawsuit against New Jersey over an executive order from Governor Phil Murphy expanding the state's sanctuary status and limiting ICE cooperation. Similar suits are already pending against Los Angeles, Minneapolis–St. Paul, and New York City, according to VisaHQ.

The Constitutional Core

The DOJ's legal theory is straightforward: the Supremacy Clause of the U.S. Constitution says federal law wins when it conflicts with state law. Full stop.

Civil rights groups argue the federal government can't commandeer local resources to enforce immigration law — and they have a point. The Supreme Court has repeatedly ruled that the feds can't force state officers to do federal work. That's called the anti-commandeering doctrine, established in Printz v. United States (1997).

But there's a difference between commandeering and obstruction. States refusing to actively help ICE is one thing. States passing laws that actively block federal operations, deny federal agents standard law enforcement tools, or require employers to tip off workers before federal agents arrive — that's a different legal animal. As VisaHQ noted, the Supreme Court has never squarely resolved where that line is.

These lawsuits may force it to.

What Mainstream Coverage Is Getting Wrong

Right-leaning outlets like Breitbart and Fox News have covered the operational and legal arguments thoroughly. What they've mostly skipped: the legitimate anti-commandeering precedent that sanctuary jurisdictions will lean on in court. This isn't just Democratic obstruction theater — there's real constitutional law behind it, and the administration could lose some of these cases.

Left-leaning outlets, meanwhile, have framed this almost entirely around immigrant community fear — which is real — while largely ignoring the specific legal violations alleged: states giving their own cops tools they actively deny to federal agents is discriminatory treatment under any straightforward reading.

Both things are true: immigrant communities have legitimate fears, and states cannot selectively obstruct federal law enforcement based on political disagreement.

What This Means for Regular People

If you live in Maine, Massachusetts, Oregon, Washington, New Jersey, or New Mexico, your state government is now in federal court. Taxpayer money on both sides is funding this fight.

If the DOJ wins — and on the license plate issue especially, the legal ground looks solid — sanctuary policies as currently structured are dead. States will have to cooperate with federal immigration enforcement or face court orders.

If the sanctuary jurisdictions win, the precedent cuts the other way: the federal government's ability to conduct immigration enforcement in uncooperative states gets significantly constrained.

Either way, the Supreme Court is probably the final destination.
