A group of Republican governors is preparing a compromise plan for their peers in Congress who want to roll back Obamacare’s Medicaid benefits, asking them to preserve the law’s expansion of coverage to millions of poor people.

The compromise proposal has been initiated by a group including Ohio Governor John Kasich and Wisconsin Governor Scott Walker, and would hold on to parts of the Affordable Care Act’s expansion of the program. It’s meant to satisfy Republican goals of repealing Obamacare and giving more control of Medicaid to the states, while also maintaining coverage of people such as childless adults and those just above the poverty level. It would also open the door for states such as Wisconsin to broaden Medicaid eligibility.

The compromise plan and the effort to promote it was described by senior state officials, who spoke on condition of anonymity because it isn’t yet public. The group also includes Utah, Arizona, and Tennessee, according to the officials. The proposal was presented to larger groups of governors in the past week during their winter meeting in Washington, according to the officials.
