Thousands of people flooded streets across California Saturday as part of a national day of action against President Donald Trump and his administration’s policies. The protests coincided with a military parade in Washington D.C. and President Trump’s 79th birthday.

Protesters in San Francisco spent the day blocking the entrance to an unmarked building in the South of Market area. Immigrants had been told to report there in what some believed was a trap by U.S. Immigration and Customs Enforcement to capture people for deportation.

Protesters were back at a building in San Francisco's South of Market neighborhood on Sunday, where people who were working on their immigration status received a notice to report in person.

The outburst of public dissent occurred over the weekend after ICE began raids across Los Angeles. ICE said on Saturday that its “operations in LA this week” had resulted in 118 arrests of immigrants in Southern California.

Hundreds marched again in San Francisco to protest the ongoing ICE raids in California, the second day of largely peaceful protests marred by incidents of violence and arrests.

SAN JOSE — Hundreds of people gathered Monday evening in San Jose, Oakland and San Francisco to protest deportation efforts by U.S. Immigration and Customs Enforcement, as well as to stand in solidarity with protesters in Southern California.

Journalists and advocates say San Francisco police detained multiple reporters and interfered with First Amendment rights during recent protests against immigration raids.

More than 150 were arrested at immigration enforcement protests in San Francisco's Financial District Sunday evening, with police officers injured and significant property damage left behind, authorities said.

While tensions escalate as protests against ICE continue to grip major cities, "No Kings" demonstrations are underway across the U.S.
