What new precedents has the Trump admin set to date, that Dems will now be able to claim "Why not, they did it..." when they regain power in the future?

Trump and his top people seem to have stretched the limits of what was once considered acceptable political speech and action. It has caught most people by surprise, considering he was more "reined in" in his last term, but his new advisors are more activists (many TV hosts and personalities...a precedent in itself) and not political veterans who were used to a certain level of speech and civility.

So what are the big and small examples to date, say from his election victory date? Words and deeds only please, and not theories.
