A second John Doe investigation is underway related to Walker’s recall election financing.

August 2012: Milwaukee County Prosecutors Opened A New Secret John Doe Investigation Into Recall Election; Target Of Secret Investigation Is “Almost Certainly” Walker’s Recall Campaign “According to the Journal Sentinel, “In August 2012, Milwaukee County prosecutors filed a petition seeking to launch the John Doe investigation into the recall races prompted by Gov. Scott Walker’s legislation to curb the power of state employee unions. From the outset, the probe focused on possible ‘illegal campaign coordination between (name redacted), a campaign committee, and certain special interest groups,’ according to a filing signed by the five district attorneys in the case. The campaign committee under the microscope? Almost certainly it’s the Friends of Scott Walker, the governor’s campaign committee. ‘Good guess,’ said one source familiar with the probe. ‘That’s it.’” [Journal Sentinel, 2/3/14]
