Keith Gilkes, Gov. Scott Walker's former chief of staff and campaign manager, told reporters Thursday after a forum at Marquette University that he is cooperating with prosecutors investigating Walker's tenure as Milwaukee County executive, WisPolitics reported Friday.
Gilkes did not return a phone message left on his cellphone Thursday.
Gilkes is the latest former top Walker aide to provide information in the ongoing John Doe investigation that has resulted in convictions for four former Walker associates for illegal campaign activity and embezzlement.
Also cooperating are Walker's current spokesman, Cullen Werwie, and past spokeswoman, Fran McLaughlin; and his former chief of staff in Milwaukee County, Tom Nardelli.
According to the online news site:
Gilkes told reporters that he "had no knowledge" of a private wireless router system that allegedly was part of a secret email system in the Milwaukee County Courthouse.
Asked if a similar router exists in the state Capitol, Gilkes became angry.
"That's just absurd, I'm done," he responded and walked away.
Gilkes also was asked about court documents released in the sentencing of former Walker aide Kelly Rindfleisch that showed daily conference calls between Milwaukee County staffers and Walker's 2010 campaign for governor.
"It was simply a scheduling and mechanical process element balancing the work of elected officials and the campaign at the same time. You have to make decisions about who's assigned what responsibilities, whether they be political or their official duties," WisPolitics quoted Gilkes as saying.
“And at all times, (Walker) has to be available for contact by official office or the campaign. It was an opportunity to explain where he could be reached."
Gilkes was quoted as saying he couldn't comment any further on the investigation being conducted by Milwaukee County Assistant District Attorney Bruce Landgraf "because of my cooperation with the DA."
“I'm not going to comment on that," Gilkes was quoted as saying. "It's part of the legal proceeding that I'm not allowed to talk about."
Gilkes also told WisPolitics that he's no longer working for Walker.
