MILWAUKEE (AP) – A top official with Wisconsin’s elections board is scheduled to be called as a key witness in a federal trial over the state’s photo voter-ID law. Kevin Kennedy is the director of the state’s Government Accountability Board. The board is tasked with enforcing the voter-ID law, which requires that voters show photo ID at the polls. Kennedy has been named as one defendant in the federal lawsuit. He’s set to testify Thursday. The voter-ID law passed in 2011 but has been put on hold pending a number of legal challenges. The federal trial began Monday in Milwaukee and is expected to last two weeks. So far most of the witnesses have been people who lack basic ID and had trouble getting photo IDs that are appropriate for voting.
