What's he's trying to hide?
Here's the categories:
Grand Jury Rule 6(e): Pure stonewalling, He can ask the district court to order release.
Sources and Methods: That material was likely in a separate annex
Ongoing investigations: They need to remain secret but unlikely that this material is in the main report. Again, I can't imagine
Executive Privilege: It sounds like POTUS publicly waived executive privilege but the language that the White House deferred to the AG is troubling but would likely be subject to judicial review.
Barr should do a nickle in Florence for even thinking about that one. @FBIWFO
So now what? Now it's time to throw Trump overboard but keep the KochBrothers and their fully paid for Congress out of it.
