All military personnel are under instructions not to obey illegal orders. If they believed that the president was violating his oath to the Constitution, or the honour and full faith of the US Government, it was not only legal, but IMPERATIVE, that they protect the nation from ALL enemies, foreign or DOMESTIC, and that applies especially if the President is violating the Constitution or the safety and security of the nation.
Trump's lawyer are now claiming that Trump was being extorted by these women, which is the very definition of a "security risk". If you can be the victim of extortion or blackmail, you shouldn't be President. Who else has dirt on Trump?
Given that Trump really did have hookers in his hotel room is Moscow, and really does like watching women piss on one another, and really is involved with sleazy women, the pee tape doesn't sound so far fetched any more. What else do these dictators have on Trump?
