"To summarize all of this bluntly: Trump’s son, son-in-law, and then-campaign manager agreed to a secret meeting with a foreign agent, working for an enemy to the United States — in Trump Tower — under the guise of obtaining damaging information against an American political opponent that, at the time, they had no way of knowing, or seemingly any regard, for how it was obtained. I’m sorry folks, but the way I read Article III, Section 3 of the United States Constitution: Treason against the United States, shall consist only in levying war against them, or in adhering to their enemies, giving them aid and comfort. That June 9th meeting sure seems to constitute treason."
