The probe, run jointly by the Justice Department and the Department of Homeland Security, seeks individual voter records but not the ballots themselves, CBS News reported, citing sources with direct knowledge of the matter. The investigation is separate from civil litigation the Justice Department's Civil Rights Division has already filed against the state, a lawsuit seeking to force Minnesota to hand over a complete, unredacted voter registration list.

That means Minnesota now faces federal pressure on two fronts: a criminal grand jury probe targeting specific individuals, and a civil case aimed at prying open the full voter file. The state is not alone. The DOJ is suing dozens of other states and the District of Columbia over the same voter-roll access issue.

Minnesota's response: aware, but not confirming

The Secretary of State's Office acknowledged the reporting but stopped short of confirming the subpoena outright. A spokesperson said the office is "aware of reporting by CBS News that we have received a grand jury subpoena related to an investigation into a small number of individual voters." The office cited grand jury secrecy rules for declining to confirm or deny the subpoena's issuance directly.

The statement also sought to distance the office from the mechanics of voter registration. The office said:

"Election security is a top priority of the Office of the Minnesota Secretary of State. While our office does not register voters or administer elections directly, we are committed to supporting the local election officials across our state who do to ensure that our elections continue to be fair, secure, and accurate."

That framing deserves a second look. Minnesota's Secretary of State oversees the statewide voter registration system. If the state's top elections office says it doesn't register voters directly, the question becomes: who does, and who is responsible when non-citizens end up on the rolls?

A pattern of federal scrutiny in Minnesota

The voter-roll subpoena lands in a state already under intense federal investigation on multiple fronts. The DOJ recently served grand jury subpoenas to Governor Tim Walz, Attorney General Keith Ellison, Minneapolis Mayor Jacob Frey, St. Paul Mayor Kaohly Her, and officials in Ramsey and Hennepin counties, AP News reported. That investigation examines whether Minnesota officials obstructed or impeded federal immigration enforcement through their public statements and actions during a major ICE operation in the Minneapolis, St. Paul area.

The DOJ subpoenas targeting Walz and Frey added a new dimension to the federal government's widening conflict with Minnesota's political leadership. Trump administration officials have argued that Walz and Frey went beyond mere rhetoric, that they demonized federal officers and encouraged residents to take action against ICE operations, the Washington Times reported. Before learning of the subpoena, Walz had urged residents to track and record ICE "atrocities" for possible future prosecutions.

Minneapolis Mayor Frey pushed back on the subpoenas. He said:

"We shouldn't have to live in a country where people fear that federal law enforcement will be used to play politics or crack down on local voices they disagree with."

But the federal government's position is that this is not about politics. It is about whether state and local leaders actively interfered with lawful federal enforcement, and whether non-citizens are sitting on voter rolls that state officials have resisted turning over.

The voter fraud question in Minnesota

How big is the problem? Heritage Foundation data cited in the CBS report shows 138 cases involving some form of voter fraud in Minnesota between 2004 and 2025. That figure covers a wide range of conduct over two decades. It does not isolate non-citizen voting specifically, and the current grand jury probe is focused on a narrower question: whether specific individuals who are not U.S. citizens registered or voted.

Republican state Rep. Pam Altendorf framed the issue plainly. As Newsmax reported, Altendorf said: "We are asking to be able to verify that the voter rolls are clean." That request, verify the rolls, is what Minnesota has resisted, prompting both the civil lawsuit and, now, the criminal subpoena.

State officials have maintained that any disclosure of voter records must comply with state and federal law. But the grand jury subpoena is itself a federal legal instrument. It does not ask. It compels. And the fact that prosecutors are seeking records on more than 125 specific individuals suggests the investigation has moved well past a general inquiry.

Concerns about Minnesota's voter rolls have been raised by state lawmakers for some time, and the federal probe now gives those concerns teeth.

A broader federal push

The Minnesota subpoena fits into a national effort launched after President Trump ordered the Justice Department and DHS in March 2025 to probe whether non-citizens remained on voter registration lists across the country. In recent months, the two agencies have coordinated law enforcement operations aimed at answering that question, not just in Minnesota, but nationwide.

The FBI has also launched several investigations into the 2020 election in Arizona and Fulton County, Georgia. Those probes, combined with the voter-roll litigation against dozens of states, signal that the federal government views election integrity enforcement as a sustained campaign, not a one-off.

Minnesota, though, stands out. The state faces a criminal grand jury investigation into its voter rolls, civil litigation over its refusal to provide unredacted voter data, a separate grand jury probe into whether its top officials obstructed immigration enforcement, and a history of alleged voter fraud schemes that have drawn national attention. Federal investigators have also previously found fraud in Minnesota's social programs, raising broader questions about the state's oversight capacity.

What remains unanswered

Key details are still missing. The date of the subpoena has not been disclosed. Neither has the court or grand jury that issued it. The identities of the 125-plus individuals whose records are being sought remain unknown, as does the specific evidence that led investigators to target them. No charges have been filed.

The gap between the investigation's scope and its public results matters. Grand jury proceedings are secret by design, and the absence of charges does not mean the probe has stalled, it may mean prosecutors are building cases methodically. But it also means the public does not yet know whether the investigation will produce evidence of widespread non-citizen voting, a handful of isolated cases, or something in between.

What is clear is that Minnesota's political leadership has spent months resisting federal requests for voter data, fighting federal immigration enforcement, and publicly encouraging citizens to document what the governor called ICE "atrocities." Now the federal government has responded not with more requests, but with subpoenas, the kind that carry the weight of a federal court behind them.

If state officials truly believe their voter rolls are clean, the simplest way to prove it is to open the books. The fact that it took a grand jury subpoena to get this far tells you something about how eager Minnesota's leaders are to find out.
