See https://freerepublic.com/focus/chat/4232208/posts?page=1196#1196 to see the exchange between Alito and the DOJ attorney.
Basically, they’re claiming that if the AG tells the POTUS that something is legal, then the POTUS has immunity. Alito asks whether a POTUS wouldn’t just choose an AG who would let him do whatever he wants.
And there you have the whole Deep State argument.
And what that would mean is that if Merrick Garland told Biden he could coordinate all this lawfare against Donald Trump and could get his FBI and CIA to threaten lawmakers and set up the J6 “insurrection”, etc..... then Biden could never be prosecuted for it.
The logical extension of that is that all the Deep State that carried out the crimes on behalf of Biden also couldn’t be prosecuted, because they were “just following orders”.
IOW, what these DOJ lawyers are trying to get SCOTUS to make permanent is the idea that the country’s AG can keep any crime in this country from being prosecutable, as long as it is carried out through the POTUS by the permission of that AG.
Extremely scary stuff.
