Protests were held in San Francisco and Sacramento to denounce ICE's arrest of immigrants in and around immigration courts, which advocates say is part of a nationwide campaign to intimidate immigrants and undermine the right to due process.

Activists were trying to gain entry inside the court building around 7:50 p.m. — and were blocking vans that they believed were carrying migrant detainees near Varick and King Streets in the West

Inside some San Francisco Bay Area immigration courthouses, Immigration and Customs Enforcement (ICE) officers are detaining people and posting signs warning migrants

The arrests by federal authorities took place on Saturday in Boston, Denver, Houston, Newark, New York City, Salt Lake City, and San Francisco.
