Protests

Sam Asghari went all in for his roots ... storming the streets of Los Angeles to stand loud, proud, and unmissable in support of the Iranian people.

In an IG video posted Sunday night, the Iranian-born model showed himself waving the Iranian flag shoulder to shoulder with massive crowds in L.A., home to one of the largest Iranian-American communities in the country.

Sam and the crowd gathered near the federal building in Westwood ... making it clear they were pushing back against political repression and calling for regime change among all the protests and chaos that have erupted in Iran.
