There is no reason for Trump's impeachment Due To a Mutual Legal Assistance Treaty (MLAT) with the Ukraine (Treaty Doc. 106-16) since Oct 18, 2000. You see clearly now that a dangerous amount of Americans are as mentally slow as a sack of wet mice. No I mean, really: they have limited learning capacity, with no paper book reading. They only know how to comment FIRST! and Brawndo has electrolytes. Trump is allowed to ask on criminal matters about Ukraine, and the other countries listed below. They tried to mention this MLAT treaty idea on FOX's The Five show and quick shut up and said 'you win'.
