Protesters blocked a main highway leading into Fountain Hills where Republican presidential front-runner Donald Trump held a campaign rally Saturday.
Watch video from the protest in the player above.
Air15 video showed protesters blocking Shea Boulevard with a couple Maricopa County Sheriff Deputies on scene.
The protesters parked their cars in the middle of the road, unfurling banners with anti-Trump slogans and chanting "Trump is hate." The disruption caused a lengthy traffic backup, and drivers honked their horns in frustration.
MCSO officials say at least three people were arrested.
