(CNN)-Minnesota Rep. Michele Bachmann changed her mind about signing the "Cut, Cap and Balance" pledge, but made a critical addition before doing so.
Bachmann is seeking the 2012 GOP nomination for president and previously vowed that she would not sign the pledge because it didn't go far enough.
But the three-term congresswoman remedied that concern Monday when she signed onto the agreement endorsed by nine other GOP presidential candidates, and added on a condition of her own: that candidates agree to repeal and defund health care reform legislation passed over one year ago and signed into law by President Obama.
"The principles that are found in the 'Cut, Cap and Balance' pledge will put us in the right direction for fundamentally restructuring the way that Washington, D.C. is currently spending our tax dollars," she said at a press conference held in South Carolina, one of the key early primary states.
And she added the important caveat saying, "However, in signing this pledge I'm also adding an additional line. In addition to cutting spending this year-not out into the future but this year-and in addition to guaranteeing a true cap in spending that will put us on a path to balance and also enforcing a balanced budget amendment we must also add this line and that's to repeal and defund Obamacare."
Bachmann joins former Massachusetts Gov. Mitt Romney, former House Speaker Newt Gingrich, Texas Rep. Ron Paul, businessman Herman Cain, former Pennsylvania Sen. Rick Santorum, former Minnesota Gov. Tim Pawlenty, Michigan Rep. Thad McCotter and former New Mexico Gov. Gary Johnson as the tenth member of the GOP presidential pack to sign onto the pledge. It proposes to cut federal spending in the next fiscal year by $380 billion, cap spending at 18 percent of the size of the economy within five to six years, amend the Constitution to require Congress to balance the budget every year and make it more difficult for lawmakers to raise taxes.
