MINNEAPOLIS – The brouhaha over University of Minnesota President Joan Gabel taking a second job with a university insurance carrier isn’t the first ethics quagmire that the current UM Board of Regents has gotten itself into. Last summer the regents appointed one of their fellow members — retired Duluth business executive David McMillan — as interim chancellor at UM -Duluth despite his lack of academic background. The criticism: The regents have become an Ol’ Boys Club that’s oblivious to perceptions of conflicts of interest.
