Supporters of Wisconsin Governor Scott Walker are being targeted by a state's special prosecutor with subpoenas, demanding they turn over documents dealing with the 2011 and 2012 recall campaigns that were designed to unseat Walker.

The Wall Street Journal reports that there are two subpoenas from special prosecutor Francis Schmitz requiring the release of "all memoranda, email . . . correspondence, and communications" both inside the subpoena targets and also between the subpoena targets and roughly 30 conservative groups. Some of the groups involved are the Friends of Scott Walker and the Republican Party of Wisconsin, the League of American Voters, Wisconsin Family Action, Wisconsin Manufacturers & Commerce, Americans for Prosperity—Wisconsin, American Crossroads, and the Republican Governors Association.

One subpoena also wants to ferret out who the donors to the conservative groups are, stating its demand for "all records of income received, including fundraising information and the identity of persons contributing to the corporation."

The beginning of this latest action against conservative groups originated in the office of Milwaukee County Assistant District Attorney Bruce Landgraf. Landgraf works for Milwaukee County Democratic District Attorney John Chisholm, and the timing is highly suspicious, because the subpoenas were issued just before Democrat Mary Burke announced her candidacy for Governor. Because the investigation is taking place under Wisconsin's John Doe law, which forbids the subpoena's targets from disclosing its contents publicly, the targets cannot publicly defend themselves, which makes it difficult to ascertain how severe the action is.

But Eric O'Keefe, the director of the Wisconsin Club for Growth, confirmed he received a subpoena in early October and revealed that at least three of the homes of the targets of the subpoenas were raided by law-enforcement officers who grabbed their computers and their files.
