He will have a plane waiting to take him to a country that does not have an extradition agreement with the United States. Whether he takes any of his family with him I don't know. He is a selfish SOB. Will he care if Ivanka or Jared get stuck with criminal charges? Will he invite them to move to a foreign country to live until they die? We will see.
He is too cowardly to face the consequences of his actions. Always has been. Always will be. Unless he takes a poison pill (idea not my own but that of a friend) what will he do? Stay and face the music? Hahahahahahahahaha. No seriously?
