Short of rewriting the constitution, that just isn't going to happen. The president is immune to prosecution for any crime committed in office and has unlimited power to pardon anyone else of any federal crimes.
And if the Democrats even attempt to do anything of the sort, people will just consider it a partisan witchhunt. It will be litigated all the way to a SCOTUS that's stacked with Trumpist ideologues.
(The UK has the opportunity to do this before the fash get into power, but we can watch it being fumbled in real time)
then a new constitution it is!
> The president is immune to prosecution for any crime committed in office
That's a misreading of the SC decision. If he walks down the street and murders someone, unless he can make a case that it was an official act, then he wouldn't have immunity. He'd need to demonstrate that he has the Constitutional authority to murder people on the street, and he doesn't, so it wouldn't be an official act and he wouldn't have any immunity.
whether or not you believe this is a pass from the Supreme Court, it opens up a whole new unexplored space of lack of culpability.
If Trump continues to have enough influence in the SCOTUS after he's done being president, then yes, you could imagine they contort any action into an official act. But that'd be a failure of the next government to first establish a less biased SCOTUS (either by packing it or removing existing justices).
It's majority conservative, but that's not the same thing as what you're claiming here.
It has 3 members appointed by Trump, but even that doesn't make them Trumpist ideologues.
Not a conspiracy theory, this is an open discussion topic among federal judges within their own conferences.
Quite a perfect storm.
