(CNN) The Trump administration announced last week its plan to roll back Medicaid by capping federal spending on the government program that one in five Americans depend on for health care coverage.

One crucial component to the plan, which would depend on buy-in from state officials, was to find a state governor willing to sign on to this next step in Trump's crusade against the Affordable Care Act. The perfect dupe would have to hail from a conservative state that hadn't yet expanded Medicaid, be ideologically committed to cutting federal spending, and most of all, would have to be willing to sell out their state's interests in favor of what makes Trump look and feel good. On Monday, they found him.

Oklahoma Governor Kevin Stitt announced during his State of the State address Monday afternoon that -- after six years of refusal by conservative lawmakers in the state to expand Medicaid under the ACA -- he would be embracing the Trump administration's block grant proposal.

Under block grants, federal funding for state Medicaid programs would be capped rather than reflective of each state's economy and the needs of its residents. States would be given the authority to shape coverage under Medicaid for its residents, including who is covered and what benefits they receive -- a flexibility that Republicans have long touted as encouraging innovation.

But experts warn that this flexibility would largely be used to make new cuts to benefits: limiting prescription drug coverage and reducing the scope of benefits covered, imposing new out-of-pocket costs on enrollees, and making it harder to get covered in the first place. The groups hardest hit by such restrictions would include the working poor, low-income Americans who are just above the poverty line but do not have access to private insurance.
