Three electors in Arizona, including Republican state chair Tom Morrissey, have revived the question of whether Obama was born in the United States.
They voiced their doubts during the ceremony that affirmed AZ's electoral college votes - which were all cast for Mitt Romney.
"I'm not satisfied with what I've seen," Morrissey explained, referring to the birth certificates Obama has produced.
Governor Jan Brewer distanced herself from the move. She said the electors were "entitled to their own opinion," but added, "I happen to disagree."
