Newsom vows to sue if Trump deploys National Guard troops to San Francisco, setting up a major constitutional clash.

Gov. Gavin Newsom on Thursday nudged Californians to be cautious about President Donald Trump’s sudden decision to pause a planned federal immigration surge in the San Francisco Bay Area, warning that the president often changes his mind.

California's governor said Trump was "coming for another of our cities" amid report that federal law enforcement agents were being sent to Bay Area.

“We’re gonna go to San Francisco,” Trump said during a Fox News interview. “The difference [from Chicago] is, I think they want us in San Francisco.” Newsom wasn’t having it. “Fact check: Nobody wants you here,” Newsom wrote on X. “You will ruin one of America’s greatest cities.

"Clearly, business leaders made the phone call to Donald Trump," Newsom said. "He decided - for the moment - on the basis of some very powerful and wealthy people who make phone calls to him to back off because it seemed to be in everyone's financial interests that they not make a spectacle of San Francisco.

Gov. Gavin Newsom has a long relationship with Marc Benioff, the chief executive of Salesforce, that dates back to a different era in San Francisco.
