The Wisconsin Supreme Court ordered prosecutors to destroy all the material collected, during their secret probes into Gov. Walker's 2012 recall campaign and activities of his aides while he served as Milwaukee County Executive. Now D.A. John Chisholm and investigators are asking Federal Judge Lynn Adelman to preserve certain materials, while remnants of the cases continue. Those include a lawsuit a former Walker aide has filed against prosecutors. They claim they could need the evidence to defend themselves.
When the state high court shut down John Doe 2 - ruling that the Walker recall campaign and independent funders did not violate the law in coordinating their activities, the court ordered investigators to destroy all evidence they had collected or return it to witnesses.
