Some Wisconsin Democrats say evidence shows Republican Governor Scott Walker was involved in illegal campaigning when he was Milwaukee County executive. But that's not the way the county's district attorney sees it.
John Chisholm announced Friday the investigation that started six months before Walker became governor has ended without any charges against Walker. Four former aides and a campaign donor have been convicted on charges ranging from theft to misconduct in office.
Assembly minority leader Peter Barca says Walker should take responsibility for people he trusted, hired and supervised. And Democratic Party chairman Mike Tate says he hopes all documents related to the case are made public.
A judge has ordered that documents gathered in the investigation remain under wraps.
Walker says he's glad the investigation is over. He's always maintained he didn't know county workers were illegally campaigning on the job.
