This is intended not only to get Trump out and punish him and his family over something, which even if whatever it is is true, pales in comparison with what the Clintons did and do on a daily basis and which is uninvestigated by Mueller and his team of Clinton contributors, but also to provide an example to anyone else with money and power who just might decide to expose or challenge the Establishment in the future - don’t do it or else we will bring the full force and power of the corrupt Deep State down on your head, your family, your allies. “The CIA has six ways to Sunday to get back at you”. The one thing that Chuck Schumer ever said that I agree with. This is so far from what the Founding Fathers created and so damned close to the Stasi/KGB/Cheka/Gestapo.
