Multiple Republican senators on Wednesday criticized the House-passed Obamacare replacement plan after a Congressional Budget Office report estimated the bill's effects.
GOP senators are working to pass a health-care proposal, though some lawmakers have suggested they could scrap the House plan entirely.
The nonpartisan CBO estimates that the American Health Care Act will lead to 23 million more uninsured people in 2026 than under current law. It also finds that average premiums will generally fall, though whether states decide to take waivers allowed under the plan will affect how much the costs change.
But sick Americans in many states and people above 64 years of age could see costs spike under the bill, the CBO said.
"Congress's focus must be to lower premiums with coverage which passes the Jimmy Kimmel Test. The AHCA does not. I am working with Senate colleagues to do so," said Sen. Bill Cassidy, a Republican from Louisiana, in a statement.
The "Jimmy Kimmel Test" refers to a term Cassidy coined after the late-night TV host told the story of his son, who was born with heart defects. Cassidy has said the "test" is whether children in that situation would get the health care they need.
