This also happened before he was a sitting president, so all the stuff about “Bush Iraq war crimes” and “Nixon’s burglary” and similar historical presidential baggage is mostly irrelevant, at least in terms of new precedent.
The social/civil consequences of this sort of criminal indictment before election is enough to kill a presidential campaign and has enough times in history. As it should be.
This is behaviour before/after presidency when the stakes are far lower.
