Wisconsin Supreme Court has allowed three district attorneys to appeal to the US Supreme Court over a closed, secret investigation into whether Gov. Scott Walker's campaign illegally coordinated with conservative groups during the 2012 recall election


MADISON, Wis. (AP) -- The Wisconsin Supreme Court has allowed three district attorneys to appeal to the U.S. Supreme Court over a closed, secret investigation into whether Gov. Scott Walker's campaign illegally coordinated with conservative groups during the 2012 recall election.

The Milwaukee Journal Sentinel (http://bit.ly/1QjRrqX) reports the state Supreme Court issued its 4-1 unsigned decision Friday evening.

However, Wisconsin's high court denied the prosecutors help from a national law firm.

The state Supreme Court found that Milwaukee County District Attorney John Chisholm, Dane County DA Ismael Ozanne and Iowa County DA Larry Nelson cannot share sealed documents with three private attorneys. Those private attorneys work for a national law firm that won a similar case before the U.S. Supreme Court.

In July, the Wisconsin Supreme Court ended the John Doe investigation.
