Health Secretary Robert F. Kennedy Jr. said the new actions — which come after previously announced Medicaid funding deferrals in those states — are part of the administration’s strategy to “stop the fraud before it happens” rather than claw back problematic spending after bad actors are prosecuted, as previous administrations had done.

“We have a duty to stop the payments, demand answers and then follow the evidence wherever it leads,” Kennedy told a news conference.

The tactic is part of the administration’s sweeping campaign to show it’s cracking down on fraud and saving taxpayers money when rising healthcare costs and other economic stressors have made affordability a top voter concern in November’s midterm elections.

In March, Vice President JD Vance launched a new anti-fraud task force at the request of President Donald Trump, bringing together officials from various departments to use data and technology to identify and investigate suspected wrongful use of federal dollars.

But the federal government hasn’t provided “data or explanation on how the deferral amount was calculated or what it was based on” to Minnesota, said John Connolly, the temporary commissioner and state Medicaid director for Minnesota’s Department of Human Services.
