Wisconsin grand jury likely to investigate John Doe leak

MADISON — Wisconsin Attorney General Brad Schimel says the state Department of Justice will likely convene a grand jury to investigate a leak of evidence collected during a secret investigation into whether Gov. Scott Walker's recall campaign circumvented state campaign finance law.

Schimel tells the Wisconsin State Journal the leak investigation would be best suited to the protected environment of a closed courtroom.

The grand jury would investigate a leak to the Guardian US, which published hundreds of documents from a John Doe investigation into how Walker raised millions of dollars for a supposedly independent group to help win his 2011 and 2012 recalls.

The grand jury plan comes after the Wisconsin Supreme Court last month rejected Schimel's request to appoint a court official known as a "special master" to investigate.
