The Wisconsin Supreme Court on Wednesday refused to revisit its ruling, to shut down the John Doe investigation into Gov. Walker's recall campaigns. Justices ruled 4-1.
The court also concluded that the appointment of Francis Schmitz as special prosecutor was improper.
Milwaukee County District Attorney John Chisholm launched the investigation in 2012, to look into whether the governor's campaign illegally coordinated with outside conservative groups on issue ads.
The Supreme Court halted the investigation this past July, ruling such coordination was legal.
