But first: As Republicans on Capitol Hill try to repeal and replace the Affordable Care Act, we're going to spend the next couple of nights hearing what patients and health care providers think should be done.

Our team visited West Virginia and Virginia, which made very different decisions about Medicaid. West Virginia did commit to expanding Medicaid through Obamacare. But Virginia is one of 19 states that didn't. The state's Republican-controlled legislature voted against expanding the program to 400,000 more citizens because of concerns over costs.

Tonight, we visit a clinic providing free care in the western corner of Virginia, a region that strongly supported the election of President Trump.
