I read the IG is finished, but it was sent back to the subjects of the report for review and correction, as is customary. Or something like that.
The report could be done, but if there were criminal referrals made by the IG, it cold delay the release due to presentation to a Grand Jury.
Again, I think this conspiracy was bigger than anyone ever imagined. Nothing would be sweeter than to hear the report was released simultaneously with the arrests of Brennam, Clapper, Clinton, Strzok, McCabe, and Comey.
