TOPEKA, Kan. (AP) — A Kansas Court of Appeals research attorney has been fired after using offensive language in a tweet about the state's former attorney general. Sarah Peterson Herr was a research attorney for Kansas Court of Appeals Judge Christel Marquardt. Herr posted her comments about former Attorney General Phill Kline to the Twitter social media site while Kline was appearing before the state Supreme Court as part of an ethics investigation. Herr commented on Kline's facial expression, saying "Why is Phil Klein(sic) smiling? There is nothing to smile about, douchebag." Kansas Supreme Court Chief Justice Lawton Nuss said Monday that Herr had been fired and that her case had been referred to other offices for possible ethical violations. Herr has apologized, and said she didn't realize her posts could be read by all Twitter users.
