On February 25, 2026, the day after Trump used his State of the Union address to put him in charge of a “war on fraud,” Vice President JD Vance announced with CMS Administrator Mehmet Oz that the administration would “temporarily halt certain amounts of Medicaid funding” to Minnesota. Oz said the state would not receive a $259 million Medicaid reimbursement that month, a figure he said was based on an audit of the last three months of 2025. The money would be held until Minnesota proposed and acted on a corrective action plan, and Oz gave Gov. Tim Walz 60 days to respond, warning that the state could “rack up a billion dollars of deferred payments this year.”
The administration cited fraud in Minnesota's social programs, including the Feeding Our Future case and allegations involving day care and autism services. Vance said the state had been “so careless with federal tax dollars that we have to turn the screws on them a little bit.” Asked by NBC News whether the administration could withhold money Congress had appropriated, he said he was “quite confident” it had the legal authority. Oz said, “These schemes disproportionately involve immigrant communities.” CMS's letter to the state said the frozen funding included payments to state-only health programs for “individuals lacking a satisfactory immigration status” and to Medicaid services it considered at high risk of fraud.
Walz responded on X: “This has nothing to do with fraud,” adding that “these cuts will be devastating for veterans, families with young kids, folks with disabilities, and working people across our state.” A day later he called the freeze “totally illegal and unprecedented” and part of a “reckoning and retribution” campaign against Minnesota, while unveiling an 18-point anti-fraud package. Walz, the 2024 Democratic vice presidential nominee, is a frequent White House target.
On Monday, March 2, Attorney General Keith Ellison and the state Department of Human Services sued CMS and HHS over about $243 million of the deferral, arguing that it violated the Administrative Procedure Act and due process and that the federal government had “weaponized Medicaid against Minnesota as political punishment.” Ellison's office said the cuts amounted to about 7% of the state's quarterly Medicaid funding. In early April, U.S. District Judge Eric Tostrud, a Trump appointee, declined to block it, finding the challenge premature and writing that “some of the legal theories Minnesota asserts are novel, and the law does not support them.”
Correction (October 14, 2026): An earlier version said the administration withheld the funds over Minnesota's refusal to comply with immigration enforcement. That was wrong: the administration's stated reason was fraud in the state's Medicaid and social programs, and the title and summary have been rewritten. The lawsuit was filed on March 2, not March 3, and challenges about $243 million of the deferral. The summary now reports the April ruling that let the deferral stand. Unsupported claims were cut: a figure of 1.4 million enrollees, a reference to legal scholars comparing the move to Nixon-era impoundment, and the state's argument as previously described, which has been replaced with the claims actually made in the complaint.
Severity note (October 15, 2026): this entry was rated serious when it described the freeze as punishment for immigration noncooperation. With the stated reason corrected to fraud, and a federal judge having declined to block the deferral, no violation of law has been established; what is documented is a contested use of funding power with material but bounded impact on one state's Medicaid program, which fits the rubric's moderate tier.
