In Friday’s court filing, Johnson and Jordahl noted that Milwaukee County District Attorney John Chisholm, who initiated the John Doe investigation in 2012 before it expanded statewide, and Attorney General Brad Schimel have both said the leak constituted a crime.

They also said John Doe Judge David Wambach, who replaced Judge Gregory Peterson earlier this year, has declined to pursue a contempt of court inquiry and that the district attorneys who were party to the investigation should not be responsible for prosecuting the leak because it may have originated in their office.

The district attorneys didn’t immediately respond to a request for comment.

Johnson and Jordahl wrote the Attorney General should lead the investigation.

They also said Schimel said privately that the leak could have been perpetrated by a hacker, but Schimel spokesman Johnny Koremenos said Schimel has never said that publicly or privately.

“If in fact a hacker was involved,” the court filing says, “legitimate ongoing law enforcement investigations, court records, personal information, and even personal safety all may be in peril. For that matter, public confidence in the operation of the courts themselves, and of the ability of the government to assure data safety, may be in peril.”

Koremenos said DOJ “does not comment on or discuss specific details that could jeopardize a potential or ongoing investigation.”
