The California Governor has sued the U.S. President over the mobilization of the National Guard, calling it “an unmistakable step toward authoritarianism.”

Newsom said he was aware of Immigration and Customs Enforcement (ICE) running "checkpoints, checking people's IDs" in Los Angeles.

“The President of the United States just called for the arrest of a sitting Governor,” Newsom wrote on social media. “This is a day I hoped I would never see in America. I don’t care if you’re a Democrat or a Republican, this is a line we cannot cross as a nation — this is an unmistakable step toward authoritarianism.”
