More than 100 federal agents, including members of U.S. Customs and Border Protection, are being dispatched to Coast Guard Base Alameda and will begin arriving Thursday, a source familiar with the operation told the San Francisco Chronicle.

The move marks the Trump administration’s latest escalation in immigration enforcement and could spark a legal showdown with San Francisco officials who have vowed to block any deployment of National Guard troops.

President Donald Trump has repeatedly threatened to send troops to San Francisco, telling Fox News that his administration intends to “make it great again.” Gov. Gavin Newsom condemned the plan, accusing Trump and adviser Stephen Miller of seeking “chaos.”

City Attorney David Chiu said San Francisco will sue to prevent federal troops from patrolling city streets.

Trump has cited the Insurrection Act as a possible legal basis for deployments, with similar operations already occurring in Los Angeles, Memphis, Chicago, Washington, D.C., and Portland.

California Governor Reacts

California Governor Gavin Newsom responded on X (formerly Twitter) saying, “California has seen enough. President Trump and Stephen Miller’s authoritarian playbook is coming for another of our cities, and violence and vandalism are exactly what they’re looking for to invoke chaos. Help keep yourself and your communities safe. Remain peaceful.”

Newsom also posted a video to X:
