Nothing should ever be redacted OR classified except for the actual names of secret agents and the precise specs of current military gear.
Trump should order sessions to release all documents unredacted. If he has a problem with that, fire him.
There is plenty that needs to be classified; however, higher OCAs shouldnt have to play these games. When Congress or the President call for materials, no flunky should be redacting anything.
Few areas of law are as clear as classification, unless youre a Clinton. The President has supreme authority to classify or declassify. This is sheer politics and people should be held accountable. The original classification authority cannot overrule a superior authority. This entire charade needs to end with people in jail.
There is a heck of a lot more than that that needs to be classified.
The problem is that information cannot legally be classified to prevent embarrassment. And embarrassment is precisely why a lot of the material in this case is classified.
