Surprise Trump visit at Wis. polling station may violate law

Donald Trump may have violated a Wisconsin election law that prohibits election activities from taking place in close proximity to polling locations.

According to the Milwaukee Journal-Sentinel, the Republican presidential front-runner greeted voters outside a fire station in Waukesha, Wis. on Tuesday afternoon that had been set up as a polling station for the Wisconsin primary.

Pictures and a video of the billionaire mingling with voters were posted to Twitter around 12 p.m. ET.

Michael Haas, an elections administrator for Wisconsin's Government Accountability Board told the Journal-Sentinel that existing statutes forbid campaign signs and brochures from being distributed, and election activities from taking place within 100 feet of voting.
