Rep. Joe Wilson, R-S.C., says he will not apologize to the House for yelling, "You lie," during President Barack Obama's health care speech to a joint session of Congress last week.
House Democratic leaders are demanding Wilson apologize from the House floor.
Wilson had accused the president of lying when he said illegal immigrants will not be covered under his health care plan.
He has apologized to the president for the outburst, but House Democrats are saying it is not enough.
"I've apologized one time, the apology was accepted by the president, by the vice president, who I know. I am not apologizing again," Wilson told Fox News Sunday when asked if he would apologize on the floor of the House.
House Democratic leaders have given Wilson an ultimatum. He has to apologize to the entire House or face a formal resolution of disapproval.
Wilson and other Republicans maintain that the president is not being truthful on the health care issue.
"People know my civility, they know that this was a onetime event, and it was out of frustration. I believe in the truth. What I heard was not true," Wilson said.
