Wilson apologized shortly after the speech for how he acted out: “This evening I let my emotions get the best of me when listening to the president’s remarks regarding the coverage of illegal immigrants in the healthcare bill. While I disagree with the president’s statement, my comments were inappropriate and regrettable. I extend sincere apologies to the president for this lack of civility.”
