“Let the speaker speak,” his supporters in the room yelled as the protesters left.

The speaker then took back control of the room.

“I appreciate that 95 percent of you, maybe even 99 percent of you,” he said “want to have an intelligent discussion.”

He added, to chuckles in the auditorium, that the “one percent” was preventing such a discussion.

Gingrich then began his discussion about brain science, saying things like “The brain will turn out to be the area that has the most growth.”
