Gov. Gavin Newsom said Sunday that he intends to seek a court order in an attempt to stop President Trump’s deployment of California National Guard troops to Oregon.

Calling the president’s action a “breathtaking abuse of power,” Newsom said in a statement that 300 California National Guard personnel were being deployed to Portland, Ore., a city the president has called “war-ravaged.”

“They are on their way there now,” Newsom said of the National Guard. “This is a breathtaking abuse of the law and power.”

Trump’s move came a day after a federal judge in Oregon temporarily blocked the federalization of Oregon’s National Guard.

The president, who mobilized the California National Guard amid immigration protests earlier this year, has pursued the use of the military to fight crime in cities including Chicago and Washington, D.C., sparking outrage among Democratic officials in those cities. Local leaders, including those in Portland, have said the actions are unnecessary and without legal justification.

“The Trump Administration is unapologetically attacking the rule of law itself and putting into action their dangerous words — ignoring court orders and treating judges, even those appointed by the President himself, as political opponents,” Newsom said.

In June, Newsom and Atty. Gen. Rob Bonta filed a federal lawsuit over Trump’s mobilization of the state’s National Guard during immigration protests in Los Angeles. California officials are expected to file the court order over Sunday’s deployment using that existing lawsuit.

Newsom has ratcheted up his rhetoric about Trump in recent days: On Friday, the governor lashed out at universities that may sign the president’s higher education compact, which demands rightward campus policy shifts in exchange for priority federal funding.

“I need to put pressure on this moment and pressure test where we are in U.S. history, not just California history,” Newsom said. “…This is it. We are losing this country.”
