Now the full (if redacted) version of the Mueller Report is being released, it's quickly becoming apparent that Barr's four-page "executive summary significantly mischaracterized the report's contents. In particular, in emphasising that there was no "collusion" he was putting the emphasis on something that Mueller never looked for. as Mueller himself wrote, “[C]ollusion is not a specific offense or theory of liability found in the United States Code, nor is it a term of art in federal criminal law,” the Mueller report reads. “For those reasons, the Office’s focus in analyzing questions of joint criminal liability was on conspiracy as defined in federal law.” So Mueller was investigating criminal conspiracy, and it is clear Trump did his best to obstruct that investigation from going ahead. I don't think Trump can be impeached, but certainly his conduct besmirches his Presidency, and that of William Barr besmirches his time in office too.
