Ahead of a Donald Trump speech in Fountain Hills, AZ, protesters parked their cars on the highway, blocking a major route to the site of a Donald Trump campaign rally, which continued as planned.







Maricopa County Sheriff Joe Arpaio, a prominent Trump supporter, said that three protesters were arrested.

The protesters parked their cars in the middle of the road, unfurling banners reading "Dump Trump" and "Must Stop Trump," and chanting "Trump is hate." Traffic was backed up for miles, with drivers honking in fury.



Protesters were chanting, "Donald Trump, shut it down, Phoenix is the people's town."



Demonstrators also marched through a crowd that gathered at the edge of a park in Fountain Hills just before Trump arrived.



The protesters, who earlier had blocked the main highway leading to the event, were outside the perimeter set up by the Secret Service around the main rally site but still surrounded by thousands of Trump backers.



The demonstrators were barely visible behind the Trump supporters, who waved signs saying "Hillary for Prison" - referring to Democratic front-runner Hillary Clinton - and "Joe for VP," referring to Arpaio.

"We had a little problem," Arpaio told the crowd at the event later. "Demonstrators were trying to disrupt.Three of them are in jail. If they think they’re going to intimidate you the next president of the U.S., it’s not going to happen."
