California officials, including Attorney General Rob Bonta and San Francisco City Attorney David Chiu, have vowed to oppose any federal deployment of military forces to the city, citing concerns over sovereignty and community safety.

San Francisco Mayor Daniel Lurie and California Governor Gavin Newsom condemned the deployment, claiming it was meant to provoke violent protests and criticizing federal tactics as fear-inducing.

Local leaders and residents have expressed strong opposition, with the mayor preparing for possible deployment and community groups organizing rallies and vigils against federal actions.

The U.S. Coast Guard is supporting federal agents from U.S. Customs and Border Protection (CBP) with a base in Alameda, near San Francisco, to help track illegal immigrants and enhance border security.

The Department of Homeland Security states that law enforcement efforts focus on targeting criminal illegal aliens involved in serious crimes like murder, rape, and terrorism in major cities including San Francisco.

CBP reports that the operation primarily targets criminal illegal aliens such as murderers, rapists, gang members, and terrorists, with Coast Guard support at Alameda.

This deployment is part of former President Trump’s broader campaign of mass immigration arrests in major cities, justified by the Insurrection Act, despite legal challenges and opposition from state officials.

Border Patrol has expanded enforcement activities in Democratic-led cities like Chicago and Los Angeles, conducting operations at worksites and public places, which has sometimes led to local backlash.

Rumors of a larger-scale invasion involving 1,500 agents circulated on social media, but these claims remain unsubstantiated.

Sources including The San Francisco Chronicle and The New York Times confirmed the deployment, citing officials familiar with the operation amid rumors of a larger influx of agents.

The federal government has partially mobilized California National Guard troops, with about 300 still federalized under Trump’s order, though some have been sent to Oregon amid ongoing legal disputes.

Local immigrant advocacy groups, such as Bay Resistance, are preparing for the operation by organizing legal rights training and community defense efforts.

A small protest at dawn outside Coast Guard Island in Alameda saw demonstrators singing hymns and holding signs against ICE and federal troops, signaling strong local opposition.
