Republican lawmakers are aggressively pushing a proposal to repeal and replace the Affordable Care Act.

Senators Lindsey Graham and Bill Cassidy’s legislation would take funding for “Obamacare” and give it to states in the form of block grants.

California Healthline Reporter Emily Bazar explains what’s at stake with the bill ahead of her panel discussion Thursday titled The ACA: What Happens Under Trump.
