Im gonna tell you Qbert, the president of UW Madison had better distance himself from these people real fast since it appears most of them are in the university system.
I would get them in and find out if they were in on this and get their resignations ASAP. If I were the Governor, I would call him/her up and say that if he/she doesnt act, the university will suffer as a result.
The Dean, the whole bunch.
