Prosecutors file motion to intervene in Gov. Walker probe appeal

MADISON — The remaining prosecutors in a secret investigation into Gov. Scott Walker's recall campaign have filed a motion to preserve their rights to appeal a ruling that halted the probe.

Five district attorneys began investigating whether Walker's campaign illegally coordinated with outside groups. A judge later appointed special prosecutor Francis Schmitz to run the probe at the prosecutors' request.

The state Supreme Court halted the investigation this summer and this month rejected Schmitz's request to reconsider, saying he lacked legal standing. The high court gave the original prosecutors until Friday to attempt to join the case.

Two prosecutors said this week they won't intervene. On Friday Milwaukee County District Attorney John Chisholm, Dane County District Attorney Ismael Ozanne and Iowa County District Attorney Larry Nelson filed a sealed motion to intervene.
