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.

Across the country, an estimated 5 million protesters took part in more than 2,000 protests, according to the American Civil Liberties Union, a co-sponsor of the nationwide protest. In the Bay Area, more than 50 protests were planned stretching south from Gilroy north to Santa Rosa.

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.

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.

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.

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.

Motorists in two cities across the nation have struck “No Kings” protesters, according to multiple reports. Police detained two motorists whom they say intentionally drove into crowds of protesters in San Francisco, California and Culpeper, Virginia. There is no reason to believe the two incidents are connected.
