“Cant we instead get multiple investigations underway for treason, conspiracy, and sedition?”
Need to go step by step. First investigate leaks and see what other things arise out of that investigation.
Not wise to hit the public with treason without having a path that leads to accusations such as that.
Get the low hanging fruit first; they can lead you to bigger and better things when they see their life flashing before their eyes.
At this point I trust Bill Barr to follow this to wherever it leads.
