Two former aides to Wisconsin Gov. Scott Walker are facing charges they participated in political fundraising on public time. The aides worked for Walker when he was Milwaukee County executive. An investigation found that Walker’s office used a private email network to communicate campaign-related material in 2010. Another former Walker employee was recently charged with embezzling thousands of dollars from a fund for the families of U.S. soldiers. Walker is facing a potential recall following his attempts to slash the rights of public sector unions.
