Romney doubles down over debt

(CNN) - Mitt Romney, the frontrunner for the GOP presidential nomination, responded Tuesday to criticism that he has been too quiet during the debt ceiling negotiations, largely reiterating his position in the debate.

"We cannot lose sight of the need to move the President toward meaningful fiscal responsibility," Romney said in a statement to CNN. "A vote on raising the debt ceiling has to be accompanied by a major effort to restructure and reduce the size of government."
