MADISON, Wis. (AP) — Wisconsin Ethics Commission administrator Brian Bell is asking the commission to investigate his conduct to clear his name after Republicans have questioned his impartiality. Bell made the request at a meeting of the commission Friday. He says results of the investigation would show that he has conducted himself in a nonpartisan, professional manner. Republican Senate Majority Leader Scott Fitzgerald and Assembly Speaker Robin Vos have called for Bell to resign because lawmakers have lost confidence over his ability to lead because he used to work for the former Government Accountability Board. Ethics Commission chairman David Halbrooks says commissioners could subpoena records and have witnesses testify under oath as part of their investigation.
