When organizers of the Stop Iran Rally turned up the music while Glenn was speaking in front of the Capitol Tuesday, the audience reacted with a message that was loud and clear.
"Turn that off! Speak! Speak!" the audience could be heard chanting as Glenn turned to the organizers and posed a challenging question.
"You can either let me speak and turn the music off or I'll call it a day, which do you prefer?" Glenn said.
The music didn't come on again until after Glenn finished speaking and stepped away from the podium. But there was more Glenn wanted to say.
