No word on Souder's response. Trust me, if he would have laughed, it would be all over the papers.
Souder's response is shown on the video link. Very gracious, as you might expect from a Republican.
He's not the type of man to laugh or say something disparaging. I felt sort of sorry for her after the first time she walked out, then she started in on what "an embarrassment" Mark Sounder has been then she walked out again and my sympathy evaporated.
