A federal judge has blocked an attempt by the Trump administration to subpoena Minnesota Gov. Tim Walz and other state officials, calling it an effort to “harass and retaliate against them.”

In a ruling unsealed Monday, U.S. District Judge Patrick Schlitz found the “dominant purpose” of the subpoenas was to “coerce Minnesota officials into assisting the federal government with enforcing civil immigration law and to harass and retaliate against them for failing to do so.”

The subpoenas were served in January as part of an investigation into whether Walz and other officials obstructed or impeded law enforcement during a sweeping immigration operation in the Minneapolis-St. Paul area.

The subpoenas, which seek records, were sent to the offices of Walz, Attorney General Keith Ellison, Minneapolis Mayor Jacob Frey, St. Paul Mayor Kaohly Her and officials in Ramsey and Hennepin counties.

The judge ruled that there appeared to be “extremely weak to nonexistent” connections between the information sought in the subpoenas and any possible criminal violation. The subpoenas seek materials “that largely if not entirely relate to constitutionally protected conduct,” the judge wrote, noting that Minnesota has the legal right not to devote its resources to enforcing federal immigration law.

The Justice Department “is not conducting a criminal investigation,” the judge wrote, “but is instead using the grand jury process for other (unlawful) purposes.”

The evidence that the subpoenas were issued for unlawful reasons is overwhelming, the judge said, arguing that the Justice Department “has struggled — without success — to identify a single plausible investigatory justification” for them.

Walz, in a statement, called the ruling “a victory for the rule of law and our democracy.”

“The U.S. Justice Department is pursuing criminal investigations into the President’s political opponents,” said Walz, the 2024 Democratic nominee for vice president. “This case was just one example of that, but we are seeing daily reminders of this administration’s lawlessness – in Minnesota and around the country. We all must continue to seek justice and uphold the rule of law.”

Ellison said “it should disturb every American that Donald Trump is weaponizing the criminal justice system against people he disagrees with.”

The subpoenas “a politically motivated retaliation against our city for lawfully standing up to ICE and fighting for our residents,” Her said in a statement, referring to U.S. Immigration and Customs Enforcement.

Frey said the investigation was “never about justice, law, and order, but the absence of it.”

“Subpoenaing political opponents because they spoke on behalf of their constituents violates the core tenets of our democracy and human decency,” he said.

Frey also observed that criticizing government action is not a crime.

“One of the defining strengths of our democracy is the ability to challenge those in power without fear of retribution. Elected officials have both the right and the responsibility to speak honestly about how government decisions affect the people they serve,” he said.
