Dozens of protesters block traffic near a Donald Trump event in Arizona

Demonstrators march in New York City

(CNN) —  

Dozens of protesters blocked traffic near a Donald Trump event in Arizona on Saturday, while demonstrators marched in New York City to protest the GOP front-runner.

The protesters in Arizona parked vehicles sideways on Shea Boulevard, blocking both lanes of traffic into Fountain Hills, where Trump held a rally Saturday afternoon, Maricopa County Sheriff’s Office Deputy Joaquin Enriquez told CNN.

Enriquez described Shea Boulevard as the main artery into the area and the protesters’ actions were causing motorists to drive into oncoming traffic as they tried to get around them. Traffic was backed up for miles due to the blockage.

“This is causing huge issues for us,” Enriquez told CNN. He added, “We obviously have to get this road open.”

Enriquez later told CNN that three protesters were arrested and two cars were towed from the boulevard. The deputy emphasized that the arrests were due to protesters blocking the roadway, not because of the protest itself.

Protests at Trump rallies increasingly have become more contentious in recent days. Friday night, protesters outside a Trump rally in Salt Lake City, Utah, tried to breach the venue’s doors, causing police officers and Secret Service officers to abruptly shut them as Trump was speaking. And last week, scuffles between protesters and supporters in Chicago led Trump to cancel a rally there.

Trump on Saturday appeared with former Arizona Gov. Jan Brewer and Maricopa Sheriff Joe Arpaio, who endorsed the GOP front-runner in January. Arpaio rose to conservative fame with his aggressive roundups of undocumented immigrants and attention-grabbing tactics like clothing inmates in pink underwear.

Speaking to CNN’s Fredricka Whitfield earlier in the day, Arpaio said authorities are “going to do everything we can to continue to have this rally,” adding that authorities are “ready for any problems.”
