In 1974, the Supreme Court, by 8-0 vote, told Richard Nixon that he had to hand over the Watergate tapes to the Special Prosecutor, which led to Nixon’s resignation a few weeks later.
In 1997. the Supreme Court, by 9-0 vote, told Bill Clinton that he could not avoid trial on sexual harassment charges brought by Paula Jones, simply because of his Presidential duties, which led to the impeachment and trial in 1998-1999.
The point of these two cases, US V Nixon, and Clinton V Jones, is that the President is not in total charge, and can be held to account by the Court system of America.
Donald Trump is about to get the same reality check, as the case involving the ban of all immigration from seven Muslim nations goes to the 9th Circuit Court, after a District Court Judge showed courage in stopping the enforcement of the President’s executive order. This is seen by most legal experts as unconstitutional, as a violation of the First and 14th Amendments, and being used against nations that have sent no terrorists to America, while other nations that have, are not included in the ban.
Donald Trump seems to think he is above the law, and his authoritarian, autocratic and tyrannical behavior must be nipped in the bud right now!
