A key legislator is asking state and UW-Madison officials to review the process through which a subcontractor was selected to build a new scoreboard and sound system at Camp Randall Stadium, to see if the jobs should be rebid. Rep. Steve Nass, R-Whitewater, chairman of the state Assembly?s Committee on Colleges and Universities, ?is very concerned with the appearance of how this bidding process worked out,? said Mike Mikalsen, Nass? spokesman.
