MADISON, Wis. (AP) â Attorneys representing Wisconsin media groups say a judge should unseal all documents that don't reveal private information about the subjects of a secret investigation into Gov. Scott Walker's recall election and others. The groups filed a motion late Wednesday saying unsealing the documents would allow the public to oversee the actions of its judicial and executive branches of state government. Prosecutors in the John Doe investigation agree all the documents should be unsealed. Attorneys for the Wisconsin Club for Growth, which is under investigation, want to keep hundreds of pages secret. The investigation started in August 2012 and focuses on alleged illegal campaign fundraising, spending and coordination by conservative groups, the governor's campaign and others.
