In an interview with NBC News, Newt Gingrich responded to Mitt Romney's comments that he can't take the heat of negative ads.
Said Gingrich: "I'll tell you what. If he wants to test the heat, I'll meet him anywhere in Iowa next week, one-on-one, 90 minutes no moderator, just a timekeeper. He wants to try out the kitchen? I'll debate him anywhere. We'll bring his ads, and he can defend [them]."
