Mitt Romney was interrupted at a rally Thursday in Virginia Beach, Va. A rowdy audience member took advantage of a pause during the Republican presidential nominee's speech and shouted "climate change caused Sandy!" He then flashed a sign that read "End Climate Silence." While Romney seemed to take the heckler in his stride, the crowd (and security) reacted much more strongly.
The man was booed and his sign was pulled away from him. As the heckler was led out of the event, the booing was layered with chants of "U-S-A!"
The interruption came just as Romney was asking for donations to help Sandy victims. He carried on with his message after the chanting ended.
