DES MOINES, Iowa — Iowa Gov. Kim Reynolds says she supports the latest GOP effort in Congress to repeal and replace the Affordable Care Act.

The Republican governor confirmed Tuesday she backs a bill that would replace much of the ACA with a system of block grants to states. The measure is sponsored by Sens. Lindsey Graham of South Carolina and Bill Cassidy of Louisiana.

The legislation would reshape Medicaid, the health care program for the poor and disabled. It includes provisions that would let states set their own health coverage requirements and let insurers boost premiums for people with serious medical conditions.

Reynolds says the bill gives Iowa flexibility and “empowers consumers.” Several health care advocacy groups oppose the measure, warning that millions would lose coverage and others would face skimpier insurance policies.
