Cole Bartiromo told INSIDE EDITION he needed six stitches after the incident outside the Pacific Amphitheater.

"Blood was just flooding down my face. It drenched my shirt," he recalled. "I never saw a punch coming, just blood. I went down on the ground, put up my hands on the asphalt, got kicked in the sides and the ribs."

More than 31,000 people showed up to the venue to hear the real estate mogul speak. According to Trump, thousands were turned away.

Trump supporters found themselves stuck in the melee as they tried to leave the amphitheater.

On Friday, protestors broke through police barriers at the GOP state convention near Silicon Valley where Trump was a featured speaker.

Trump was forced to get out of his limo and walk up an embankment surrounded by aides and secret service agents.
