Following a contentious collective bargaining dispute in 2011, an effort began to recall Walker and Kleefisch. After examining petitions, the Wisconsin Government Accountability Board determined there were more than 800,000 valid signatures to hold a recall election. The recall election was held on June 5, 2012. Kleefisch won the recall election. Kleefisch is the only lieutenant governor in the history of any state in the United States to face recall election and ultimately survive a recall.
