There was a lot of news last week. A college-admissions scandal. A plane crash. An awful terrorist attack. Beto O’Rourke’s campaign announcement. So maybe you missed the president of the United States muse aloud about violence by his political supporters.

My column this morning is about that threat. President Trump keeps encouraging both violence and white nationalism — and white-nationalist violence is rising. That’s not a coincidence. He doesn’t deserve blame for any specific attack. But he deserves blame for using the world’s biggest bully pulpit to corrode our democracy and public safety. He’s engaging in behavior that has scary historical echoes and real-world effects.
