MADISON, Wis. (AP) -- Newly released documents show prosecutors believe Wisconsin Gov. Scott Walker was at the center of a nationwide "criminal scheme" to illegally coordinate fundraising with outside conservative groups.
No charges have been filed against Walker or any member of his staff. The documents became public Thursday as part of an ongoing lawsuit challenging the investigation by the conservative group Wisconsin Club for Growth.
One of the filings from prosecutors outlines previously unknown details about the investigation that began in 2012 as Walker was facing a recall election.
Prosecutors say Walker, his chief of staff and others who worked for him were discussing illegal coordination with a number of national groups and prominent figures, including GOP strategist Karl Rove.
