MADISON, WI (WTAQ) - Madison Police say they’re investigating a vandalism incident connected with the recall effort against Scott Walker. Officials said a rock was thrown through a window with a “Recall Walker” sign. And the rock had a note with a reference to JoAnne Kloppenburg, who almost won the April election for State Supreme Court with the help of pro-union protestors. The incident was reported Tuesday night at the Victory Café on Madison’s east side. No one was hurt, but several customers were said to be near the rock when it flew in.
