President Trump had harsh words for one of his most fervent opponents during the pre-Super Bowl interview with Fox News’s Bill O’Reilly that aired Sunday. Not President Vladimir Putin, mind you, whose alleged unpleasant habit of murdering journalists met with a shrug from the president. No, Trump lashed out at the nation’s largest state, California.

“I just spent the week in California,” O’Reilly said. “As you know, they are now voting on whether they should become a sanctuary state. So California and the U.S.A. are on a collision course. How do you see it?”
