Sens. Lamar Alexander and Patty Murray say they have reached an agreement on a bipartisan Obamacare deal to fund a key insurance subsidy program and provide states flexibility to skirt some requirements of the health care law.

There is no assurance that the agreement will get to the Senate floor, however. Republicans on Tuesday were lukewarm about the prospect of resuming debate over whether to try to prop up Obamacare after multiple failed GOP attempts to repeal the law.

The deal would include funding through 2019 for Obamacare’s cost-sharing program, which President Donald Trump cut last week. It would allow states to use existing Obamacare waivers to approve insurance plans with “comparable affordability” to Obamacare plans, Alexander said. But it would notably not allow states to duck the law’s minimum requirements for what a health insurance plan must cover.

Revised waiver language in the Alexander-Murray bill requires states to “provide coverage and cost sharing protections against excessive out-of-pocket spending that are of comparable affordability, including for low-income people, people with serious health needs, and other vulnerable populations.”
