There was an official impeachment process. It didn't complete, but it was started iirc; I expect that, had Trump won another mandate on an even slighter majority, we would have heard much more about it. Also there were a lot of active reactions, official and unofficial, which were widely reported (civil servants withdrawing information, leaking all sorts of stories to the press, scrambling to correct his actions, etc etc).

Scandals can be survived even in democracy, for sure (Dick Cheney shot a man, Ted Kennedy killed a woman, etc etc), but the accused has to work hard for it. And you could say Trump didn't really survive them, since he was voted out at the first chance.
