Six Walker confidantes and aides have been charged with felonies in the growing probe, with two convictions, and Scott Walker himself has established a criminal defense fund.
Virtually every member of Walker's political inner circle has been named in the criminal complaints, which allege a pattern of Walker corruption that began during his time in Milwaukee and almost certainly continued during his time in Madison.
