MADISON, Wis. (AP) — The Wisconsin Supreme Court has refused to reconsider its decision to end the “John Doe” investigation into Gov. Scott Walker’s recall campaign. The state Government Accountability Board and Milwaukee prosecutors launched the investigation in 2012, to look into whether the Republican governor’s campaign illegally coordinated with outside conservative groups on issue ads. The Supreme Court halted the investigation in July, ruling such coordination was legal. Francis Schmitz, the special prosecutor who led the investigation, asked the high court in August to reconsider the ruling. The court refused his request Wednesday. John Doe investigations are similar to grand jury proceedings, in that information is kept secret and prosecutors can compel witnesses to testify as they consider whether to pursue criminal charges. No charges were filed in the Walker campaign investigation.
