(ABC News) Republican presidential candidate Newt Gingrich, asked to explain Wednesday why he did not correct a voter during a question and answer session who called President Obama a Muslim, said that it’s not his job to police what voters say.

While asking a question about the economy, Bob Nolan of Lake Charles, La., told Gingrich that he believes President Obama is a Muslim and a student of Saul Alinsky.

“And I believe that it’s his policy to bring this country to its knees and ruin the United States of America. Your comment?” Nolan said.
