When Walker John Doe Stories Appear, Always Remember Walker's Best Quote

The records of more aides who worked in then-Milwaukee County Executive Scott Walker's office have been subpoenaed in the ongoing John Doe criminal misconduct probe that has already netted charges and guilty pleas.

The probe unearthed the existence of a secret email system installed less than 25 feet from Walker's office door; Doe probe documents show prosecutors have learned that Walker aides and campaign operatives used the system to communicate improperly on public time.

Milwaukee County prosecutors also made the surprising disclosure that top Walker aides set up a private Internet network to allow them to communicate with one another by email about campaign as well as county government work without the public or co-workers' knowledge.

The emails Walker officials traded via the shadow network could provide investigators with a trove of information as they pursue other angles in the case.

Each time these stories surface I go back to something that Walker told a state newspaper during the 2010 gubernatorial campaign - - a story still posted on Walker's campaign website:

When he says he believes in government transparency, it's not just a campaign slogan, Walker said.

"I don't just say that, I've lived it," he said.
