Gov. Walker’s Spokesman Given Immunity For Testimony In Corruption Probe | Two weeks ago, FBI officials raided the home of Cindy Archer, who recently served as deputy administration secretary under Wisconsin Gov. Scott Walker (R). The corruption probe appears to be investigating allegations that, during Walker’s tenure as Milwaukee County executive, staffers did political work on the public’s dime. The probe took another step forward late last week as Walker’s chief spokesman, Cullen Werwie, was granted immunity in exchange for his testimony.
