During the reading of Article II, Section I of the Constitution -- the clause that requires the president of the United States to be a "natural born citizen," an unidentified woman in the gallery screamed "Except Obama! Except Obama!" Politico's Marin Cogan adds that the woman yelled, "Help us, Jesus!" She was removed immediately.
UPDATE: I'm told that the woman who made the disruption was Theresa Cao, a birther activist and supporter of court-martialed birther Lt. Col. Terry Lakin. On December 16, she told WorldNetDaily that she was "taking his message to the White House and Congress."
