The California governor blasted Trump amid the president’s deployment of National Guard troops to the Los Angeles area.

California Gov. Gavin Newsom said Donald Trump’s threats against him and other Democrats following the president’s unilateral deployment of National Guard troops to the Los Angeles area carried all the markings of authoritarianism.

“It’s just an extraordinary moment, and I don’t want to overstate it, but these are the words of an authoritarian,” Newsom said in a Monday interview with POLITICO. “Whether he acts on it or not, the chill that creates is real, and it’s a serious moment, very serious.”

Trump and his border czar have targeted Newsom and Los Angeles Mayor Karen Bass by name with threats of arrests — and other ominous unspecified acts to be carried out by the federal government if the two don’t fall in line. Newsom spoke after a weekend of unrest — property destruction and bursts of violence — following immigration raids in the region.
