Unconstitutional Bill of Attainder with no chance of surviving a legal challenge.
Anyone who doubts that Schumer is an enemy of the Republic after this is either a stupid fool or a domestic enemy.
The Republicans have only a 7-seat advantage in the House and the Democrats are hopeful of taking control (gerrymandering has possibly made some seats easier for them to capture).
So if they have the White House, Senate, and House next year, they can pass a Bill of Attainder condemning Trump for insurrection and have him imprisoned. Of course they may deem it necessary not to call it a Bill of Attainder, but with a Supreme Court majority it would pass muster.
Not that I think this scenario is a likely one.
