Protesters blocked the entrance to the Hyatt Regency hotel in Burlingame, CA where the Republican state convention was being held, forcing Donald Trump's motorcade to make their way around to the back of the hotel. Trump hopped a fence and made his way into the hotel via a rear entrance.

Out front, there was chaos as a polyglot group of demonstrators representing several different activist groups sought to disrupt Trump's speech.

CNN:

Protesters -- some of whom wore bandanas over their faces and carried Mexican flags -- blocked off the road in front of the Hyatt Regency here, forcing the GOP front-runner's motorcade to pull over along a concrete median outside the hotel's back entrance. Trump and his entourage got out and walked into the building.

"That was not the easiest entrance I've ever made," Trump said once he began speaking at the convention, adding, "it felt like I was crossing the border."

At one point before Trump arrived, about two dozen protesters tried to rush barriers near the hotel. Police officers then rushed to the building's doors, successfully blocking the protesters from getting in. Some of the doors' handles were handcuffed from the inside so they couldn't be forced open.

Several physical altercations, including shoving, could be seen between protesters and police officers, who were using batons to push them back.

After Trump arrived, protesters took down a barrier and flooded the entrance outside the hotel, where police again blocked them from entering. They chanted, "Get him out."

Earlier in the day, Chris Conway, a 51-year-old Trump supporter who was wearing the GOP front-runner's famous "Make America Great Again" cap, claimed he was kicked, punched and spit on by Trump protesters, though he wasn't seeking medical attention. Police, apparently concerned for his safety, eventually pulled him over hedges outside the hotel and away from the crowd.

Speaking to CNN Friday afternoon, Conway said he was "not surprised" by his treatment.

"To be honest with you, I'm glad it was me and not like an 8-year-old girl being pepper-sprayed or something like that," he said.

Burlingame Police Lt. Jay Kiely said later Friday that five people were arrested, including one who was with the crowd when it tried to rush the Hyatt's entrance. One injury was reported, but Kiely did not know whether it was a police officer, protester or supporter who was hurt or the extent of the injury.

Kiely estimated the crowd was in the hundreds, though he did not have a precise figure and did not know how many police officers were dispatched to the scene. He also praised the "incredible restraint" shown by authorities.
