The current probe was initiated by the Milwaukee County District Attorney's office, but now involves multiple counties. Francis Schmitz, a former assistant U.S. attorney who was once considered by President George W. Bush for the post of U.S. attorney for the eastern district of Wisconsin, is now leading the case as a special prosecutor, according to the Journal Sentinel.
"It's now spread to at least five counties," a source told the paper. The same source said that Milwaukee County Assistant District Attorney Bruce Landgraf had been investigating "all over the place."
The case apparently opened in February 2012. And according to the Journal Sentinel, the investigation is looking at a number of issues, including the recall races, a current legislative leader, and the 2012 gubernatorial recall contest between Walker and Milwaukee Mayor Tom Barrett.
