The US Congress took another stab Wednesday at President Barack Obama's namesake healthcare programme, sending legislation to repeal the so-called Obamacare to the president's desk.
Conservative Republicans, who hold majorities in both the Senate and the lower House of Representatives, have tried many other ways to kill the ground-breaking 2010 healthcare law, but this is the first time opposition legislators have sent a repeal to the president's desk.
The measure, which Obama has vowed to veto, would repeal most of the officially named Affordable Care Act and strip federal funding for Planned Parenthood, a women's health care provider whose purported sale of aborted human fetal tissue to laboratories outraged conservatives.
The repeal, which cleared the Senate late last year, was approved by the House 240-181.
Obama's Democrats derided the vote as pointless because Republicans do not have enough votes to override a presidential veto.
Republicans see the effort as the opening round in a fresh fight over Obamacare that could energize the party's election-year efforts.
Since the Affordable Care Act went into effect in 2010, millions of Americans have bought health insurance or acquired coverage through government programmes.
