South Carolina Republican Rep. Joe Wilson, who faces a formal rebuke from his colleagues this week for shouting “You lie!” at the president during a joint address to Congress, said he would offer no further apologies.

“I have apologized to the president, I believe that’s sufficient,” Wilson said in an interview on “Fox News Sunday.”

House Democratic leaders said they would offer a resolution this week to formally admonish Wilson, unless he apologizes on the House floor, which he has said he would not do.

“It’s going to be tough because I respect my colleagues,” Wilson said of the resolution. “I respect civility and I promote civility in every way, particularly on the House floor.”

Except for last Wednesday, when Wilson called President Barack Obama a liar during the part of the president’s speech when he said the health-care overhaul would not provide coverage to illegal immigrants.

Attention to the issue has prompted Senate negotiators to revisit the issue to make sure there are provisions in place to make sure illegal immigrants do not get federally subsidized coverage.

“I think, and I didn’t mean to do this, but I certainly brought attention to” the issue, Wilson said.

The vote on the resolution is likely to reignite partisan tempers. “It will be a disgrace if they do some stunt in the House to try to humiliate this man,” said conservative commentator Bill Kristol, also on “Fox News Sunday.”

UPDATE 11:52 a.m.: Wilson released a statement on the resolution: “The American people are fed up with the political games in Washington, and I refuse to participate in an effort to divert our attention away from the task at hand of reforming health insurance and creating new jobs. Having apologized on Wednesday to the White House, we agreed that we must move forward in a civil manner to do the work the American people have sent us here to do. Health insurance reform is too important to take a backseat to political partisanship.”
