So if Biden issues an executive order that Trump, as a grave and ongoing threat to the Republic, be summarily executed by a special forces team, would that be legal? Though I suppose he could resign and be pardoned by President Harris, just to be sure.
In the immunity case his discussions are off the table. But a direction to assassinate someone as opposed to discussions about it would be diff I think.
But a lot of other stuff is not, including his directions to pence, non-executive branch government officials, the public, Jan 6th rioters, etc.
The inability to question motives is the real legal coup. An enthusiastic DOJ wanting to rid a troublesome priest finds a troll post insinuating that Trump is using Mar a Lago to store uranium. Biden treats the post as actionable intel, sends a task force to recover, and a shootout ensues. Fine, no?
