A congressional candidate in Wisconsin was arrested over an angry anti-Israel outburst at a gas station, a case his supporters call a free-speech violation.

• Matthew Art, a Green Party candidate in Wisconsin's sixth district, now faces a disorderly conduct misdemeanor after yelling at a man who confronted him.
• Police first added a hate crime enhancer because his words targeted Israel, but that was later dropped.
• The other man admitted he followed Art into the gas station and was not charged.
• Art says he was already being squeezed before this, pointing to a rare regulatory audit of his business that found nothing.
• His campaign centers on cutting off US money and weapons to Israel, and he says the arrest brought him support from across the country and abroad.

Outlook: Art's first court date falls on election day, and he plans to fight the charge before raising a constitutional challenge.
