All four remaining candidates to appear at Monday's NBC debate


After some earlier uncertainty, the Romney campaign has confirmed that former Massachusetts Gov. Mitt Romney will participate in Monday's NBC/National Journal/Tampa Bay Times debate moderated by NBC's Brian Williams.

As a result, all four remaining Republican presidential candidates -- Romney, former House Speaker Newt Gingrich, Texas Rep. Ron Paul, and former Pennsylvania Sen. Rick Santorum -- will appear at the debate, which takes place in Tampa, FL and airs on NBC beginning at 9:00 pm ET. 

The statement from NBC News Senior Vice President of Specials Mark Lukasiewicz:

"All four qualifying Republican presidential candidates have confirmed their attendance for Monday's NBC News, National Journal, Tampa Bay Times debate. Florida has often been the stage for history in politics -- we look forward to hosting a substantive and stimulating forum for the candidates to make their case to the voters in this crucial state and the whole country."
