Rebeca Olguin, a Bernie Sanders supporter who was at the scene and posted a video of the mayhem on Instagram, told ABC News she came to protest Trump and his campaign.

"There were some who were peacefully protesting while others were being more open about sharing their opinions," she wrote in an e-mail to ABC News.

Before the event started, the venue closed once it had reached capacity and individuals were trying to jump the fence to get in. They were escorted outside the gate.

The rally -- which attracted 18,000 supporters and was held in advance of the state's June 7 primary -- opened with families of people killed by undocumented workers from the Remembrance Project. They joined Trump on stage, as they have at previous rallies. "Trump is here to save us all,” said Jamiel Shaw, Sr., whose son Jamiel Shaw, Jr., was killed in 2008 when he was 17. Trump in turn took back the microphone and vowed to “Build the Wall."

Trump also took aim at his GOP rival Ted Cruz, and his newly-announced running mate, Carly Fiorina.

"[Cruz] will get an award...for the first time in the history of American politics, a man who is totally mathematically dead, has appointed a Vice President,” Trump said, later adding that Senator Cruz is “one lyin’ son of a gun.”

As for Democratic presidential front-runner Hillary Clinton, Trump said, “She’s there shouting all night long with reading from teleprompters. I’m sorta glad she won I wanna beat her more than Sanders.”

Trump will attend his first-ever state convention of the cycle Friday in California. His next rally is Sunday in Indiana.
