This story, produced by the Wisconsin Center for Investigative Journalism and Wisconsin Public Radio, was first to report on a June 13 altercation in which Wisconsin Supreme Court Justice David Prosser placed his hands on the neck of fellow Justice Ann Walsh Bradley in a dispute in her office in front of other members of the court. The article reported that the argument concerned the timing of the court's release of a decision upholding Republican Gov. Scott Walker's controversial bill to curb the collective bargaining rights of the state's public employees, and that the Capitol Police Department and the Wisconsin Judicial Commission were informed of the incident. The story also revealed that the Capitol police chief had come in to speak to the court's seven members about it. Although the initial story relied on anonymous sources, all of the facts were subsequently confirmed by on-the-record interviews, and later by police reports.
