The House passed a bill on Tuesday to repeal the Affordable Care Act for the first time in the new Congress, but Democrats appeared to show more zeal in defending the law than Republicans did in trying to get rid of it.
The measure goes now to the Senate, where the majority leader, Mitch McConnell, Republican of Kentucky, has said that the chamber will vote on legislation repealing the health law but has not announced a schedule.
Republicans in both chambers are divided over how to replace the law and how to respond if the Supreme Court upholds a challenge to insurance subsidies now being provided to millions of people under the law.
The House vote, 239 to 186, generally followed party lines. No Democrats voted for repeal. Three Republicans — Representatives Robert Dold of Illinois, John Katko of upstate New York and Bruce Poliquin of Maine — voted against the bill.
