💬KEY QUOTE: “We’re going to be fierce in terms of our response… this is the lawsuit that I will file within a nanosecond of any efforts to send the military to one of America’s great cities, San Francisco.” – Gavin Newsom
🎯IMPACT: The confrontation could lead to a landmark legal battle over the limits of presidential power under the Insurrection Act.
California Governor Gavin Newsom (D) says he will take legal action to prevent President Donald J. Trump from deploying National Guard units to San Francisco, even though the President has not yet issued such an order. Already, over 100 federal immigration agents are being deployed to the Bay Area as the Trump White House continues to ramp up enforcement actions.
“We’re going to be fierce in terms of our response,” Newsom stated during a press briefing. “We are going to be focused, and quite literally this is the lawsuit that I will file within a nanosecond of any efforts to send the military to one of America’s great cities, San Francisco.”
He characterized San Francisco as one of the safest large cities in the country and accused Trump of politicizing public safety. “Send troops to San Francisco and we will sue you, [Donald Trump],” Newsome wrote, reiterating his legal threat, in a post on X (formerly Twitter).
Meanwhile, the U.S. Coast Guard confirmed preparations at its Alameda base to support U.S. Customs and Border Protection (CBP) agents. A spokesman remarked that this effort is part of a “whole-of-government approach” to address illegal border crossings.
While President Trump has not yet issued an order to deploy National Guard units to San Francisco, the America First leader has indicated he is inclined to do so, stating: “We’re going to San Francisco and we’ll make it great. It’ll be great again.”
The Trump White House has legally defended National Guard deployments in other cities under the President’s direct constitutional authority to deploy the National Guard domestically, and additional powers granted under the Insurrection Act—though the latter has yet to be invoked.
