A federal judge denied Minnesota's emergency bid to unfreeze more than $243 million in Medicaid funds this week, ruling that the state filed its lawsuit prematurely and that the Trump administration's deferral of payments likely complies with federal regulations. The decision hands the administration a significant win in its effort to force state accountability over what officials describe as rampant billing fraud.

Judge Eric Tostrud, a Trump appointee, rejected both a temporary restraining order and an expedited preliminary injunction sought by Minnesota Attorney General Keith Ellison, a Democrat who sued the Centers for Medicare and Medicaid Services in early March after the administration paused the state's Medicaid reimbursements. In a pointed observation, Tostrud wrote in his ruling that "Minnesota has recognized it has a serious fraud problem."

That single line may be the most damaging sentence a state attorney general has faced in months, because the judge was quoting Minnesota's own admissions back at it.

What CMS found and what Minnesota wanted to stop

The dispute traces back to a Feb. 25 deferral notice from CMS, which identified questionable billing from certain care providers in Minnesota and requested supporting documentation from the state. The notice triggered an administrative process requiring Minnesota to show that the deferred amounts would be paid to legitimate reimbursement claims.

Rather than work through that process, Ellison's office went to court. His team argued the funding freeze amounted to political retribution dressed up as fraud prevention. The complaint claimed the state would suffer irreparable harm without immediate relief.

Ellison's office warned that "the administration has already stated that the deferral will recur every quarter, crippling the state budget." The state's filing also asserted that deferrals typically serve as a narrow auditing tool focused on a specific claim, "not... wide swaths of Medicaid funding."

But Tostrud was unmoved. He found that the deferral proceedings had "just started" when Minnesota raced to court, and that no Medicaid cuts had been finalized. The state, he wrote, was asking the court to act on speculation.

"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."

The judge went further. He concluded that federal regulations do not limit the amount of money that can be deferred at once and do not prohibit CMS from pursuing deferrals and payment pauses concurrently against one state. In short, the administration was operating within its legal authority.

Vance and Oz made their intentions clear

Minnesota's complaint cited public statements by Vice President JD Vance and CMS Administrator Mehmet Oz as evidence that the deferral was politically motivated. The state's initial filing quoted the two officials and argued 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."

Vance, described in the case as the administration's fraud czar, had said the goal was to "turn the screws on [Minnesota] so that they take this fraud seriously." Oz, for his part, stated at the time that "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."

Those remarks are blunt. They are also, as Tostrud's ruling suggests, not illegal. The judge acknowledged that Minnesota "credibly complains that the federal government's deferral is historically unprecedented in its size and timing." But he noted that many of the state's arguments "concern the possibility of future deferrals and sometimes seem to muddle the regulatory distinctions between deferrals and withholdings."

In other words: Minnesota was conflating what had happened with what it feared might happen next. And courts do not issue emergency orders based on fear.

The fraud behind the freeze

The administration's pressure campaign did not emerge from thin air. The Washington Times reported that the crackdown centers on alleged Medicaid fraud especially concentrated in some Somali immigrant-linked service networks in Minnesota. Oz identified one focus area as alleged autism-service fraud, including providers accused of paying parents to obtain autism diagnoses and then billing for services not actually delivered.

Vance framed the problem as systemic, saying, "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."

That distinction matters. The administration has framed this not as a penalty against Minnesotans who depend on Medicaid, but as a reckoning with state officials who failed to police their own programs. The state could lose $259 million in deferred payments unless it produces a credible plan to combat the alleged fraud, a point the administration has pressed repeatedly.

Minnesota's fraud problems are not new, and they are not limited to Medicaid billing. The state was home to the massive Feeding Our Future scandal, one of the largest pandemic-era fraud schemes in the country. And the pattern extends into the courts themselves.

Fox News reported on a separate case in which a jury convicted Abdifatah Yusuf in a $7.2 million Medicaid fraud scheme involving a home healthcare business prosecutors said operated "out of a mailbox." Yusuf was found guilty in August on six counts of aiding and abetting theft by swindle over $35,000. But Judge Sarah West later overturned the verdict, writing that the prosecution relied heavily on circumstantial evidence, even as she acknowledged she was "troubled by the manner in which fraud was able to be perpetuated at Promise Health."

Jury foreperson Ben Walfoort disagreed with the acquittal, saying, "It was not a difficult decision whatsoever... it was beyond a reasonable doubt." Ellison's office has appealed West's decision. The episode illustrates a recurring frustration: even when fraud is identified, prosecuted, and proven to a jury's satisfaction, the consequences sometimes evaporate.

Tostrud left the door open, barely

The judge was careful not to slam the courthouse door entirely on Minnesota. He noted 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 language gives Ellison a thread to pull in future proceedings. But for now, the ruling is a clear setback for the state, and a clear signal that federal courts will not automatically intervene when the administration uses its regulatory tools to demand accountability from states sitting on documented fraud.

The ruling also fits a broader pattern of federal judges engaging seriously with the administration's legal positions. In recent weeks, courts have weighed in on everything from EEOC subpoena enforcement to immigration enforcement, with outcomes that suggest the judiciary is not reflexively hostile to executive action when the legal footing is solid.

Tostrud's opinion emphasized what CMS actually did: "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 response was to sue.

That sequence tells its own story. When a state's first instinct after receiving a fraud inquiry is to run to court rather than open its books, taxpayers are right to wonder what the books would show.

What happens next

Minnesota does not currently have access to the deferred funds during the verification process. Ellison's office has signaled it will continue pressing the case, and Tostrud's ruling explicitly acknowledged that the state might prevail later as the record develops. But the immediate practical effect is that the administration retains its leverage.

The case, styled Minnesota v. Oz, remains active. Whether the state chooses to cooperate with CMS's document requests, or continues litigating, will say a great deal about how seriously Minnesota's leadership treats the fraud that its own courts and federal regulators have flagged for years.

Not every legal fight involving the administration has gone this smoothly. A separate federal court ruling delayed the administration's push for race-based admissions transparency from universities, a reminder that judicial outcomes remain case-specific. But in Minnesota, the facts lined up, and the judge said so plainly.

The administration has also notched wins in appeals court rulings on deportation policy, suggesting a growing judicial comfort with executive enforcement actions grounded in statute and regulation rather than improvisation.

Back in Minnesota, the math is simple. More than $243 million sits frozen. CMS wants documentation. The state wants an injunction. A federal judge looked at the record and told Minnesota it came to court too early, with too little, against an agency acting within the law.

When the government asks a state to prove it spent a quarter-billion dollars honestly, and the state's answer is a lawsuit instead of a ledger, the taxpayers already know who has something to hide.
