MILWAUKEE (AP) -- A 13th person has been granted immunity in a secret Milwaukee County investigation that has already led to criminal charges against six people close to Gov. Scott Walker.
Online court records say a judge on Thursday granted Fran McLaughlin's request for immunity.
McLaughlin served as Walker's county spokeswoman from 2007 to 2010, when Walker was the Milwaukee County executive. She's now the spokeswoman for Milwaukee County Sheriff David Clarke.
When reached for comment, defense attorney Michael A.I.
Whitcomb cited court rules preventing him from discussing the case.
The John Doe investigation centers on several aides and associates to Walker before he was elected governor in 2010. The allegations range from campaigning on county time to embezzling money from a veterans program.
Walker hasn't been charged with wrongdoing.
