MADISON, Wis. (AP) — Prosecutors have asked a federal appeals court to allow an investigation into Republican Gov. Scott Walker and other conservative groups to proceed. Milwaukee County District Attorney John Chisholm and special prosecutor Francis Schmitz filed the motions Wednesday and Thursday with the 7th Circuit Court of Appeals in Chicago. They are seeking a stay in last week's ruling by U.S. District Judge Rudolph Randa that temporarily stopped the investigation, which has focused on possible illegal campaign coordination between various campaigns and conservative groups. Prosecutors had previously appealed the ruling to the 7th Circuit. They are now asking that Randa not be allowed to take any other action in the case while their appeal is pending. Randa is separately considering whether to make public dozens of pages of documents in the case.
