Three district attorneys have moved to intervene in the state’s now-stalled John Doe investigation into Gov. Scott Walker’s campaign and conservative groups, a move aimed at bringing the case before the U.S. Supreme Court.
The motion was filed by Milwaukee County District Attorney John Chisholm Friday.
It is currently under seal.
The move comes after the Wisconsin Supreme Court declined to reconsider its decision to end the probe.
Special prosecutor Francis Schmitz had made that request earlier this year.
