For the second time in 18 months, the House has passed a bill to repeal the 2010 Patient Protection and Affordable Care Act, whose provisions have begun to revamp the U.S. health-care system.

Repeal has little or no chance of passage in the Senate, where Democrats hold the majority. The White House said in a July 9 statement that President Obama would veto the House repeal bill if it were to reach his desk.

Undoing the act has been a priority for House Republicans, led by Speaker John Boehner (Ohio). The July 11 vote generally tracked party lines, as 239 Republicans and five Democrats voted for repeal and 185 Democrats opposed it. The vote came less than two weeks after the U.S. Supreme Court upheld parts of the act.
