Senate Republicans are divided on how they want to address the Affordable Care Act's (ACA) expansion of Medicaid. Not surprisingly, Senators from states that expanded coverage under the ACA are pressing to continue that funding as long as possible. Senators from non-expansion states are more willing to roll back federal support without a lengthy transition. Resolving this disagreement is central to finding a way forward to passing a full repeal and replacement of the ACA in the Senate.
