The Trump administration is facing another lawsuit over its sweeping changes to Medicaid less than a week after a federal judge ruled that implementation of work requirements would cause “irreparable harm.”

The complaint from four states, filed Thursday, alleges that the overhaul will lead to “irreparable sovereign, fiscal, and public-health harms” and that the administration does not have the authority to force states to implement these changes. Oregon Attorney General Dan Rayfield filed the suit in the U.S. District Court in Oregon, joined by Minnesota, New Mexico, and Washington. 

The lawsuit arrives less than 60 days before the Jan. 1 deadline outlined in Republicans’ One Big Beautiful Bill, which passed in 2025. It would require a Medicaid recipient  to work, volunteer, or attend school for 80 hours a month to keep health insurance, with a few exceptions for disability.
