quote, "Early 2018 - Former Ukrainian officials and Trump associates conspired to have U.S. Ambassador to Ukraine, Marie Yovanovitch, ousted."
Ousted? Conspired? Ambassadors are not ousted. They are appointed by the President and affirmed in the Senate. There is nothing nefarious about changing an ambassador with any new President. The only thing odd is when an ambassador resists their position to be changed to another.
