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.

California Gov. Gavin Newsom questions Trump's mental and physical ability as their clash over immigration enforcement rages on.

It’s a familiar playbook for the media-conscious governor who relishes trading blows with his sometime political foe.

Their clash over Trump’s deployment of military forces for anti-ICE protests in Los Angeles is far from the first time the two leaders have butted heads.
