CNN Historian: What Trump Did Was ‘Clearly Treasonous,’ Flashed Guilt

EXCERPT:

BRINKLEY: "Well, we had a vice president, Aaron Burr in 1807 who was charged with treason. There was a famous trial, and they didn't feel they had the goods to bust Burr fully. The problem with the enemy aiding and abetting, Don, is that Russia is not officially right now considered enemy of the United States. But we also know they had a cyber attack on us. So Donald Trump has got kind of the slippery slope of legal language in his favor. But the spirit of what Trump did is clearly treasonous. It's a betrayal of the United States. He threw our U.S. intelligence services, flushed them away and it came off as being a puppet of Putin. So the word treason like impeachment, like obstruction of justice, are going to be out there in public discourse louder and longer right now. But it's all going to come down in the end to what the Mueller investigation unearths. But certainly people are going to say that there's the taint of treason around this White House."
