At a news conference in Concord, N.H., Gingrich was asked by CBS correspondent Dean Reynolds why he congratulated Rick Santorum but not Romney.

Gingrich stared at the reporter and raised his eyebrows in silence, eventually drawing laughter from some of the reporters.

“Because I know you would be a man of great professionalism, I know that’s a rhetorical question. And a good one,” Gingrich said.
