"In a letter to Congress on March 24th, 2019 characterizing the Special Counsel's report, Mr. Barr stated: "In cataloguing the President's actions, many of which took place in public view, the report identifies no actions that, in our judgement, constitute obstructive conduct, had a nexus to a pending or contemplated proceeding, and were done with corrupt intent..." ...In reality we know that Special Counsel Mueller found "substantial evidence" of criminal intent and nexus to a specific proceeding as it relates to at least four, if not more, obstructive acts taken by the President of the United States. We know he directed aides to fabricate internal documents, lie about their actions, attempted to fire the Special Counsel, get then-Attorney General Sessions to "un-recuse" himself so as to exert greater control over the investigation's direction, and likely tamper with witnesses."
