MADISON, Wis. — A state lawmaker is taking issue with the University of Wisconsin-Madison?s investigation into allegations of misconduct against the school?s former associate athletic director. The office of State Rep. Steve Nass, R-Whitewater, released a statement on Wednesday that called on interim UW Chancellor David Ward “to make immediate changes to the inquiry” of senior associate athletic director John Chadima, who resigned last Friday after the allegations surfaced.
