Everybody knows what happened. There have been books. Bonginos, McCarhtys just to name two. Barr needs to write a new book?
Knowing what happened and having the specific facts/proof are two different things...going off half-cocked is how the Dems operate and anathema to what we wanted in a Trump DOJ.
And once the action begins, they will do everything they can to obfuscate and impede.
