A federal judge appointed by George W. Bush just told the Trump Department of Justice that its grand jury subpoenas against Minnesota Democrats were not law enforcement — they were harassment — and that distinction may reshape how far any administration can push states that refuse to help enforce immigration law.
Story Snapshot
- The Department of Justice subpoenaed Governor Tim Walz, Minneapolis Mayor Jacob Frey, and other Minnesota officials in January 2026, claiming they obstructed federal immigration enforcement.
- A federal judge appointed by President George W. Bush threw out the subpoenas, ruling their dominant purpose was to coerce, harass, and retaliate — not to investigate a crime.
- The judge found the Justice Department could not name a single valid investigatory reason for the subpoenas and admitted it was not actually conducting a criminal investigation.
- Immigration and Customs Enforcement (ICE) made more than 3,000 arrests in the Minneapolis-St. Paul area over six weeks, framing Minnesota’s resistance as active obstruction of federal law.
What the DOJ Said It Was Doing in Minnesota
The Department of Justice served subpoenas on Governor Walz, Mayor Frey, and four other Minnesota officials in January 2026. [1] The probe alleged they conspired to obstruct and impede federal immigration officers. The DOJ invoked a Civil War-era statute previously used against groups like the Oath Keepers and Proud Boys for hindering federal agents. [3]
ICE made over 3,000 arrests in the Minneapolis-St. Paul region in just six weeks, and federal officials pointed to that surge as proof that active enforcement was underway and that state resistance was getting in the way. [6]
The DOJ called Minnesota’s lawsuit to block the enforcement actions “legally frivolous” and argued that federal law is supreme. [8] On its face, that is a defensible position. States do not get to nullify federal immigration law.
But there is a significant legal gap between a state choosing not to help ICE and a state actively conspiring to obstruct federal officers. The DOJ’s case depended on closing that gap. It could not.
A Bush-Appointed Judge Calls the DOJ’s Bluff
U.S. District Judge Patrick Schiltz, a George W. Bush appointee, unsealed a 30-page ruling that did not mince words. He found the dominant purpose of the subpoenas was to coerce Minnesota officials into helping enforce civil immigration law and to harass and retaliate against them for refusing to do so. [2]
That is not a close call. That is a judge saying the government used its most powerful investigatory tool as a political weapon.
Judge Schiltz wrote that connections between the information the DOJ sought and any actual criminal violation ranged from “extremely weak to nonexistent.” [2] He also wrote that the Justice Department “has struggled — without success — to identify a single plausible investigatory justification” for the subpoenas.
Most damning of all, the judge found the DOJ itself admitted it was not conducting a criminal investigation but was using the grand jury process for what he called “other (unlawful) purposes.” [2] That admission alone should concern anyone who values the rule of law regardless of party.
Why the Statute Choice Matters More Than People Realize
The DOJ’s decision to use a Civil War-era obstruction statute against elected state officials is not a small detail. That law was designed to stop violent mobs from physically blocking federal officers. Applying it to a governor who publicly criticizes ICE policy and declines to redirect state police resources is a dramatic stretch.
Judge Schiltz noted the subpoenas targeted “constitutionally protected conduct” — meaning public criticism and policy decisions about how to spend state resources. [2] The Constitution does not require states to enforce federal law, and courts have said so repeatedly.

This is where the administration’s argument runs into a wall that common sense can see from a mile away. There is a real debate to be had about whether sanctuary policies make communities less safe. That debate deserves to be had honestly.
But using grand jury subpoenas to punish officials for speech and policy choices they are legally allowed to make is not law enforcement. It is leverage. And a conservative federal judge said exactly that.
The Bigger Pattern Behind This One Case
This case did not happen in a vacuum. Research from the Columbia Law Review found that ICE has systematically broadened its subpoena power to pierce sanctuary laws and force state and local governments to become what the study called “unwilling partners” in arrests and detention.
The Minnesota fight is one visible battle in a much longer, quieter war over who controls immigration enforcement on the ground. The Trump administration lost this round badly — not before a liberal activist judge, but before a jurist from its own ideological neighborhood.
The administration still has legitimate arguments about federal supremacy in immigration law. Those arguments deserve a proper legal fight with real evidence. What happened in Minnesota was not that fight.
The DOJ went to court with subpoenas it could not justify, targeting officials for doing things they were legally allowed to do, and a conservative judge shut it down. If the administration wants to hold sanctuary cities accountable, it needs a case built on facts — not pressure tactics that courts will keep throwing out.
