Wisconsin Supreme Court releases Walker-related filings

MADISON (AP) — Hundreds of filings in three cases related to an investigation involving Gov. Scott Walker have been released.

The heavily blacked-out court documents were released Wednesday by the Wisconsin Supreme Court. The filings shed light on legal arguments made by those involved in the cases, but it's not immediately clear how much new information is contained.

The cases generally involve whether Walker's recall campaign and conservative groups illegally coordinated during recall elections in 2011 and 2012.

Unnamed parties have filed two lawsuits challenging the probe's validity. Prosecutors have filed another action seeking to reinstate quashed subpoenas that halted the investigation more than a year ago.

The Supreme Court is expected to rule on the cases in late June.
