U.S. Senator David Vitter is among a group of Republican lawmakers calling for a repeal of the new health care reform law.
As Democrats celebrated, dozens of Republicans launched a campaign to undo the legislation.
Senator Vitter has introduced legislation to repeal what he calls 'Obamacare', saying the law 'will put the government between us and our doctors'.
The overhaul would extend insurance coverage to 32 million Americans who are not insured now.
