Crowds of protesters holding “Dump Trump” signs and voicing their opposition to the Republican front-runner Saturday morning brought traffic to a halt.

An hour ahead of the scheduled Donald Trump rally in Phoenix, Arizona, drivers were forced to stop their vehicles at Shea and Palisades Boulevards.

Maricopa County sheriff’s deputies arrived and summoned tow trucks to start hauling the violators away, KPHO-TV reported.

Protesters began lining up in Phoenix early Saturday morning in advance of Donald Trump’s campaign event at the Phoenix Convention Center.

“We don’t want you here in Arizona,” protester Salvador Reza told KPHO-TV. “We don’t want your hate.”

Protesters planned a several-block march to where Trump will speak later Saturday morning.

“We want to make sure that people know that not everyone is in agreement with Donald Trump,” Reza said. “There’s more than 50 percent of people who don’t want him.”

Reza was specifically addressing Trump’s hardline stance on immigration.

“He’s already talking about building walls, not bridges. In the modern era, that’s not acceptable,” Reza said.
