“While the T-word has been thrown around on the fringes of the political debate about other presidents or politicians from time to time, never in the modern era has it become part of the national conversation in such a prominent way. Never in anyone’s lifetime has a president engendered such a wave of discussion about whether his real loyalty was to a foreign power over his own country.”

“To the president’s defenders, this all sounds like a sign of what they often call Trump Derangement Syndrome. That he drives his critics to such extremes, they argue, says more about them than it does about Mr. Trump. But the president has had fewer such defenders in the last 24 hours, with prominent Republicans and even some of Mr. Trump’s traditional allies lambasting his performance and distancing themselves from him.”
