Read: Newsom demands Trump pull National Guard from LA protests

The big picture: Newsom and other Californian Democratic leaders criticized Trump and his administration on Sunday for the action, as tensions remained heightened between authorities and protesters in a weekend that saw tear gas deployed.

Driving the news: Trump in his memo said that to the "extent that protests or acts of violence directly inhibit the execution of the laws, they constitute a form of rebellion against the authority of the Government of the United States."

• However, David Sapp, the California governor's legal affairs secretary, said in a letter to Defense Secretary Pete Hegseth that local law enforcement resources were "sufficient to maintain order."

What they're saying: Newsom said the action was "a serious breach of state sovereignty" that inflamed tensions "while pulling resources from where they're actually needed," as he posted copies of Sapp's letter to his social media accounts on Sunday.

• Trump told reporters Sunday he would ensure there will be "troops everywhere" if necessary, adding: "We're not going to let this country be torn apart."
• Representatives for the White House and Pentagon did not immediately respond to Axios' requests for comment on Sunday evening.
