Another hint of things to come?
Trmp described the judge who initially banned hs ban on immigrants - he desctibed him as a "so called judge"
Not sure but in the UK that might have made Trump liable to a contempt of court charge. OK, he did this in a tweet but that does not excuse him, he is no longer a private person, every action he carries out is a matter of public interest, an indicator of his attitude to his own authority and that of others.
Nothing easy to pin down (without more research than I want to do) but odd phrases of his seem to indicate that he feels thatthe president's authority, in some areas, should be beyond question or challenge. This is, unfortunately, true with regards to certain things - like the decision to go to war and the use of nukes. But I get the feeling that Trump would like to spread that ultimate authority further down the hierachical ladder of the law. Put himself above the judiciary. Bad enough that he gets to pick the top judges.
I doubt, with America's history of local independence, it will reach full totalitarianism, not quite full fascism or 1984ism without a lot of fight back. But the damage that could be done to America as a nation, in the worst case scenario, is frightening I feel.
