Columbia, South Carolina (Reuters) - Republican presidential candidate Mitt Romney pledged on Sunday to release his tax returns this week, bowing to pressure from critics and hoping to make up for a misstep that helped rival Newt Gingrich win South Carolina's primary race.
Long considered the frontrunner, Romney stumbled badly in debates last week on his delay in disclosing his tax returns and then lost his air of being the inevitable Republican nominee after a resurrected Gingrich soundly defeated him in the third contest.
