This happened back in November 2012: Fourth former Scott Walker aide convicted in WI John Doe probe:
And remember Kelly Rindfleisch? She’s the former Walker aide who was sentenced to six months in jail and three years of probation on a felony count of misconduct in office. Walker was named as part of a team that routinely commingled political and official business, and Russell was allegedly responsible for the “unofficial networking system” out of Rindfleisch’s office. She’s out on appeal.
How do sleazeballs like Scott Walker always manage to slither out of these predicaments with nary a scratch or without charges being filed? I'm talkin' to you John Ensign, Mark Sanford, David Vitter, etc. ad nauseam.
Milwaukee County DA John Chisholm announced this morning he is closing a John Doe investigation without filing additional charges, ending the threat Gov. Scott Walker could be caught up in the long running probe. [...]
State Democratic Party Chairman Mike Tate responded that Walker's biggest accomplishment in his first two years in office was not related to the economy or education, but avoiding prosecution despite the conviction of two close aides.
Tate also requested that Scotty "release any and all information that was provided in John Doe, so the public can have full understanding." After all, Tate reminded us, Walker did promise transparency, so this would be a swell time to demonstrate a little of that.
Yeah, like that'll happen.
