MILWAUKEE (WKOW) -- A subpoena for Governor Scott Walker's testimony in an upcoming criminal trial of one of his former aides has been submitted to a Milwaukee County court.
Clerk Gina Barron for Judge David Hanscher tells 27 News the subpoena was submitted to the court Friday.
Barron says the subpoena documents show the subpoena was served on Walker's attorney, Michael Steinle.
Steinle has yet to return a call from 27 News seeking comment.
Walker was previously identified by a prosecutor as a potential witness in the October 15 trial of Kelly Rindfleisch in Hanscher's court.
But Rindfleisch's attorney, Franklyn Gimbel tells 27 News he had the subpoena served to ensure Walker's appearance.
Gimbel also says the prosecution has backed off from it's original intent to consider calling Walker as a trial witness.
Gimbel tells 27 News, if the scheduled trial takes place, he is "100% sure" he will call the governor to the witness stand.
Authorities say Rindfleisch committed misconduct by working on campaign activities in 2010, while at her government job as deputy chief of staff for Walker when Walker was Milwaukee County executive.
Authorities say Rindfleisch exchanged dozens of emails with others on behalf of the campaign of lieutenant governor candidate Brett Davis, who is now state medicaid director under Walker.
Authorities also say Rindfleisch used a secret email system, with records of emails unknown to county custodians of such records.
