I think that’s largely how it’s already worked out. There are already threads in P&E dedicated to the Jack Smith January 6th investigation, the Jack Smith Mar-A-Lago documents investigation, the Manhattan DA tax fraud/election fraud investigation and trial.

Hopefully this is working well enough. There’s no perfect way to organize discussions on someone so dedicated to criming as Trump is.
