KABC reported the anti-Trump group identified itself as “Refuse Fascism.”

One Trump supporter wearing a red "Keep America Great" hat told the news outlet he was attacked by an activist.

"I didn't know what was going on," Harim Uzziel said. "I saw a scuffle in between. One of them came to the sidewalk and he started punching me and attacking me. I had a camera in each hand so I wasn't able to defend myself."

Gregg Donovan said he purchased a ticket to the Tuesday event in Beverly Hills for $1,000 but was unable to get in because it was overbooked. He said his ticket would be refunded.

He instead waited outside with a sign to show support for Trump.

“I was very disappointed in both sides. I took a neutral stance. I just stood there with my sign the whole time, but the burning of the flag really hurt,” he told KCBS.

Trump is in California this week for two days attending multiple fundraisers.

He held fundraisers in Los Angeles and Palo Alto on Tuesday, with more events in Southern California scheduled for Wednesday.

Trump's secretive fundraiser in Silicon Valley Tuesday was also met with protests.
