Prosecutors claim Gov. Scott Walker was involved with a plan to illegally coordinate fundraising with outside conservative groups to help him and several Republican senators survive a 2012 recall election. In court documents recently unsealed, prosecutors detail a criminal scheme by Walker and top aides to circumvent state law by helping plan campaign spending by a dozen outside groups.

No charges have been filed against Walker or any of his staffers. The documents became public as part of an ongoing lawsuit by Wisconsin Club for Growth, a group at the center of the investigation. A federal appeals judge now is considering whether to permanently stop the investigation.
