The darling GOP Governor of the Tea Party, Scott Walker, is under some serious scrutiny:

Gov. Scott Walker and his top campaign and Milwaukee County aides were named Monday as part of a team that routinely commingled political and official county business.

The disclosures came during the sentencing of a former aide to Walker during his last year as Milwaukee County executive. Kelly M. Rindfleisch, 44, was sentenced by Milwaukee County Circuit Judge David Hansher to six months in jail and three years of probation on a single felony count of misconduct in office. The judge stayed the sentence pending Rindfleisch’s appeal to the Wisconsin Court of Appeals or the state Supreme Court.

In a lengthy presentation during Rindfleisch’s sentencing, Assistant District Attorney Bruce Landgraf displayed numerous emails between Rindfleisch and key members of Walker’s campaign staff in which they discussed how to manage county government in 2010, while Walker was a candidate for governor.

Repeatedly, Landgraf argued that Rindfleisch knowingly broke the law by doing campaign work at the courthouse. In a new development, the prosecutor made clear – without saying it was illegal – that top Walker campaign officials influenced, even directed, county strategy.

It hasn’t been disclosed if Walker himself is being targeted in the investigation, but it does lead you to wonder how high this thing can go.
