A member of South Carolina's Republican congressional delegation called on Rep. Joe Wilson (R-S.C.) to issue a formal apology on the House floor on Tuesday.

Wilson is under threat to apologize or face official rebuke from the House. Democrats are expected to present a resolution condemning Wilson today should he not speak out on the House floor.

Rep. Bob Inglis (R-S.C.) tweeted during today's Republican Conference meeting:

Just said to GOP Conference meeting what I said privately to Joe Wilson: apologize to House for rule violation.

Part 1: Joe Wilson apologized to President. Part 2: He should apologize to House for rule violation. That would end the matter.

Joe Wilson analogy: I speed, lose control of my car and hit your car. Part 1: I fix your car. Part 2: I pay my speeding ticket. Case closed.

Inglis last week criticized Wilson's conduct during President Barack Obama's joint session speech. Wilson shouted "you lie!" at the president after he said his health reform plan would not insure illegal immigrants.
