An escalating clash pits a Republican president looking to fulfill his mass deportation goals against a Democratic governor with White House aspirations hoping to mobilize opposition.

Trump ignited a fight with Newsom after deploying thousands of National Guard troops and 700 Marines to Los Angeles to quell demonstrations protesting the Immigration and Customs Enforcement (ICE) raids across the city. Trump has lashed out at Newsom, suggesting earlier this week that the sitting governor should be arrested.

The new line of attack from Newsom, who is widely considered a top contender for president in 2028, comes after he told Fox LA earlier this week that Trump “is not the same person that I dealt with just four years ago, and he’s incapable now of even a train of thought. He’s making things up.”
