They read the constitution out-loud to Congress...
Rep. Frank Pallone, D-N.J., read the section of the Constitution that set out the eligibility requirements for the presidency. As Pallone read the words "No person, except a natural-born citizen, or a citizen of the United States ..." a woman yelled out "except Obama, except Obama!" The presiding officer asked that she be ejected, and she was. Police later said Theresa Cao, 48, of New York, was charged with unlawful conduct and disruption of Congress.
So-called "birthers" claim President Barack Obama is ineligible for his office, contending there's no proof he was born in the United States. Some suggest he was actually born in Kenya, his father's home country. The Obama campaign provided a certificate of live birth in 2008, an official document from Hawaii showing the president's birth date, city and name, along with his parents' names
