It was unclear whether the rest of the Bay Area would also be free from federal enforcement efforts, as was promised for San Francisco.

California Gov. Gavin Newsom said Wednesday he was prepared to sue the Trump administration in a “nanosecond” if the White House moved forward with the deployment of the National Guard to San Francisco. “Send troops to San Francisco and we will sue you,@realDonaldTrump,” Newsom wrote plainly in a post on X.

The San Francisco district attorney said in an interview that she came up with the strategy after seeing federal agents repeatedly roughing up people in Los Angeles and Chicago.

Trump has claimed “unquestioned power” and indicated he could justify deploying federal troops to San Francisco under the Insurrection Act, an 1807 law that gives the federal government authority to suppress a rebellion or civil unrest.

Dozens of federal agents are on their way to the Bay Area this week, a source with direct knowledge of the operation tells NBC Bay Area.
