APPLETON, WI (WTAQ) - Governor Scott Walker said today he would not use campaign donations to have defense lawyers represent his former Milwaukee County aides. The Republican governor has transferred $160,000 in campaign gifts to his legal defense fund – which he can use for himself, his campaign, or those working on his campaign. During a stop in Appleton today, Walker said he built up the legal defense fund so he could have attorneys provide thousands of documents to the Milwaukee County district attorney’s office, which is conducting a two-year-old John Doe investigation. The probe deals with Walker’s former aides in the Milwaukee County executive’s office. Five ex-Walker aides and associates have been charged, and one has struck a plea deal in exchange for cooperating with prosecutors. Democrat Tom Barrett, the opponent in Tuesday’s Walker recall election, has made the John Doe the biggest focus of his campaign in recent days. Walker has said he won’t be touched in the John Doe probe, but Barrett said Wisconsin voters deserve to know any involvement he’s had in the investigation. But the governor says he’d be breaking the law by disclosing secret John Doe testimony that prosecutors can use in considering charges.
