I said over a year ago, and Andrew McCarthy, National Review, just said the same: it is a conspiracy investigation, broader and broader, and takes time time time. (Will the Bitem cabal try to limit or end the effort?) Targets such as Michael Sussman (Perkins Coie) are urged to make a deal and give evidence against another target... and so on; it takes time.
As the graphic states, it has grown quite broad. It has not yet reached Animal Control! 🙀
