According to the report, the pro-Trump rally was also a pro-veteran march, with organizers collecting donations for homeless veterans.

The organizers also expected approximately 3,000 demonstrators to attend the event, which was originally planned to take place at a nearby event center.

Fearing clashes between pro-Trump and anti-Trump crowds, the event was later moved to a different location, CBS Los Angeles noted.

The number of arrests wasn't immediately clear. Fights started about an hour into the demonstration, according to KTLA.
