(By Alicia M. Cohn, The Hill) - Newt Gingrich said Nancy Pelosi is living in a fantasy world if she thinks she has dirt on him.

"She lives in a San Francisco environment of very strange fantasies and very strange understandings of reality," Gingrich said Wednesday as he laughed off the notion that the House minority leader could derail his bid for the GOP presidential nomination.

"I have no idea what's in Nancy Pelosi's head," Gingrich said on NBC's "Today" show. "If she knows something, I have a simple challenge: Spit it out."
