The CSPAN camera did not show the protester. I recognized her voice. Maybe its a good thing that she did not get even more publicity by having her name on the photo.
It appears to have been Medea Benjamin of Code Pink..
She disrupted the prime minister of Iraq's speech thanks to Major Owen (D-NY). See this thread for more, if you're interested.
