A federal judge has halted a Justice Department investigation aimed at several Minnesota officials, delivering a sharp rebuke to the Trump administration’s efforts to scrutinize state leaders over their stance on immigration enforcement.
In a ruling made public Monday, U.S. District Judge Patrick Schiltz invalidated subpoenas issued to the office of Minnesota Governor Tim Walz and five other state and local government entities. The subpoenas were part of a broader federal inquiry examining whether Minnesota officials had interfered with immigration operations during a period of intensified enforcement activity earlier this year.
The decision effectively freezes a Justice Department probe that sought to determine whether Democratic officials had obstructed federal immigration efforts as thousands of agents were deployed across parts of Minnesota for large-scale deportation operations.
Schiltz, who was appointed to the bench by former Republican President George W. Bush, was unsparing in his assessment. He concluded that the government’s legal basis for the investigation was deeply flawed, describing its justification as “risible” and finding that the subpoenas were driven by motives far removed from legitimate criminal inquiry.
According to the ruling, the primary objective of the subpoenas appeared to be pressuring Minnesota officials into assisting federal immigration enforcement and punishing them for refusing to do so. The judge stated that the evidence overwhelmingly suggested the investigation was intended to coerce, harass and retaliate against public officials rather than uncover criminal wrongdoing.
The Justice Department defended its actions, saying it remains committed to investigating any unlawful interference with federal law enforcement activities and would continue to do so within the bounds of the law.
The dispute traces back to January, when federal authorities issued sweeping subpoenas seeking information about state and local policies connected to immigration enforcement. Among those targeted were Governor Walz, Minneapolis Mayor Jacob Frey and Minnesota Attorney General Keith Ellison.
Federal officials argued they were examining whether local leaders had violated laws related to obstructing government operations or aiding undocumented migrants. However, Minnesota officials challenged the subpoenas in court, contending that the investigation was politically motivated and designed to punish critics of the administration’s immigration agenda.
Judge Schiltz agreed that the government had failed to present meaningful evidence that any laws had been broken. He noted that the link between the information sought and any potential criminal conduct ranged from tenuous to virtually nonexistent.
“The fact that connections between the information sought in the subpoenas and any possible criminal violation range from extremely weak to nonexistent only adds to the overwhelming evidence that these subpoenas were not issued to investigate, but to harass, coerce, and retaliate,” the ruling stated.
The investigation emerged amid heightened tensions surrounding federal immigration operations in the Minneapolis area. The enforcement campaign sparked protests and confrontations between residents, activists and federal authorities, becoming one of the most contentious immigration battles of the year.
Walz welcomed the ruling, describing it as a victory for democratic principles and the rule of law. Ellison echoed that sentiment, accusing the administration of using the justice system as a political weapon against opponents.
The ruling adds to a growing list of judicial setbacks for Justice Department investigations that critics have characterized as politically driven. It also underscores the continuing clash between federal immigration authorities and state officials who have resisted aggressive enforcement measures.
