U.S. Sen. David Vitter says he will reintroduce a bill repealing the Patient Protection and Affordable Care Act, known derisively in conservative circles as "Obamacare," when the Senate convenes for its first day of session Tuesday. U.S. Sen. David Vitter says he will reintroduce a bill repealing the Patient Protection and Affordable Care Act, known derisively in conservative circles as "Obamacare," when the Senate convenes for its first day of session Tuesday. The legislation comes on the heels of passage of a bill repealing the law in the Republican-controlled U.S. House. But Vitter's gambit in the Senate is largely symbolic: Democrats control the upper chamber and the White House has vowed to veto any legislation that repeals the landmark health care bill passed last year.

The nonpartisan Congressional Budget Office has estimated that the House Republicans' plan to repeal the Patient Protection and Affordable Care Act will add $230 billion to the deficit over the next decade.
