The federal judge rejected Minnesota’s emergency bid to unfreeze more than $243 million in Medicaid funds, finding the lawsuit premature and indicating the Trump administration’s deferral of payments likely follows federal rules.

A federal judge denied Minnesota’s emergency motion to lift a freeze on Medicaid reimbursements, ruling the state sued too early and that the federal deferral likely complies with regulations. That decision handed the administration a clear legal win in its effort to press states to address suspected billing fraud. The ruling came from Judge Eric Tostrud, who was appointed by President Trump.

Judge Tostrud refused both a temporary restraining order and an expedited preliminary injunction sought by Minnesota Attorney General Keith Ellison. In his opinion he wrote that “Minnesota has recognized it has a serious fraud problem.” That line came from Minnesota’s own filings and undercut the state’s emergency claims.

The dispute began with a Feb. 25 notice from CMS identifying questionable billing by certain providers in Minnesota and asking the state for supporting documents. That notice started an administrative verification process meant to show whether the deferred amounts were tied to legitimate claims. Instead of working through that process, the state went to court.

Ellison’s team argued the deferral was politically motivated and warned the move would cause irreparable harm. The state’s filing said “the administration has already stated that the deferral will recur every quarter, crippling the state budget.” The complaint also claimed deferrals are usually narrow audits and argued they are “not… wide swaths of Medicaid funding.”

“Minnesota’s request for a preliminary injunction depends on assuming that predicted future events come to pass. As a rule, the law does not allow a preliminary injunction to be issued based on assumptions like these.”

Tostrud found the deferral process had only “just started” when Minnesota rushed to court and that no Medicaid cuts had been finalized. He stressed the state was asking the judiciary to act on speculation rather than on a concrete administrative outcome. The judge also concluded that federal rules do not cap how much can be deferred at once.

The court held that CMS can pursue deferrals and payment pauses at the same time against a single state, meaning the agency acted within its statutory authority. That legal view gives Washington tools to press states that fail to police fraud in federal programs. For Republican critics of mismanagement, the ruling validated the administration’s use of existing regulatory mechanisms.

Minnesota’s complaint pointed to public statements by Vice President JD Vance and CMS Administrator Mehmet Oz as evidence of political intent. The filing quoted that “Defendant Oz and Vice President Vance made clear that the only way for Plaintiffs to recoup the withheld money is for [the Minnesota Department of Human Services] to act on a corrective action plan that meets their approval.” The state argued those comments showed the deferral was about politics, not oversight.

Vance, described in the case as the administration’s fraud czar, said the goal was to “turn the screws on [Minnesota] so that they take this fraud seriously.” Oz said “this quarter-billion-dollar deferment is hopefully going to get on the radar screen for the state of Minnesota and make sure they are responsive to our requests.” The judge acknowledged those comments but found they did not make the deferral illegal.

Tostrud noted Minnesota “credibly complains that the federal government’s deferral is historically unprecedented in its size and timing.” He also observed the state’s arguments sometimes blurred regulatory lines between deferrals and withholdings. In short, the court viewed Minnesota’s filing as driven more by fear of future action than by present, enforceable harm.

The administration says the deferral responds to concentrated alleged fraud in parts of Minnesota’s provider networks, including certain immigrant-linked service groups. One focus area cited by officials involves alleged autism-service fraud, with accusations that some providers paid parents for diagnoses and billed for services that were not delivered. Those allegations drove the agency’s decision to demand documentation.

Vance framed the issue as systemic: “You have people who are billing the government millions, tens of millions, billions of dollars in taxpayer dollars saying they’re providing a service but there’s no follow-up to ensure they’re actually providing those services.” Oz added, “This is not a problem with the people of Minnesota, it’s a problem with the leadership of Minnesota.” Those blunt lines helped justify the federal pressure campaign.

The administration says the state could lose up to $259 million in deferred payments unless Minnesota produces a credible anti-fraud plan. That number hangs over state negotiations and gives CMS leverage in demanding accountability. The agency has repeatedly pressed the point that document production and corrective planning are the route to recovery.

Minnesota’s fraud issues reach beyond Medicaid. The state was involved in a major pandemic-era scandal and has seen prosecutions related to home healthcare billing schemes. In one case a jury convicted Abdifatah Yusuf in a $7.2 million fraud, but a judge later overturned the verdict while expressing concern about how the fraud occurred.

Jury foreperson Ben Walfoort said, “It was not a difficult decision whatsoever… it was beyond a reasonable doubt.” Ellison’s office appealed the overturning of that conviction, underscoring the recurring frustration when convictions are later set aside. Those episodes are part of the federal government’s argument that stronger oversight of state programs is justified.

Tostrud did not preclude Minnesota from prevailing later, writing that the state “has identified reasonable legal concerns regarding the deferral’s nature and scope and the federal government’s motivations for initiating it.” He added, “It is possible the record may support these concerns in the future. Today it does not.” That leaves room for future litigation as the record develops.

The judge also emphasized that “CMS, in other words, identified concerns and requested documents. It did not express a conclusion that these claims or any part of them would be disallowed.” The agency asked questions; Minnesota’s immediate response was to sue. That sequence shaped the court’s view of who moved too quickly into litigation.

For now, Minnesota lacks access to the deferred funds while CMS conducts verification. The case, styled Minnesota v. Oz, remains active and will test whether the state cooperates with document requests or continues to litigate. How Minnesota proceeds will show whether its officials treat these fraud flags as a priority or as a political fight.
