If there is evidence in the grand jury interviews that implicates the president in a crime or sub-criminal conduct against American interests, the public has a right to know. Given the public importance, Barr should be working to facilitate a process to allow at least some members of Congress an ability to review the full the report. Instead, he appears to be treating this as any other grand jury matter subject to 6(e). I don't think that is right.
And I do not think the democrats are the ones acting in bad faith here. Again, the public has a right know, through Congress if necessary to protect sensitive information but there must be public oversight. Barr's letter, listing four grounds for redaction and suggesting that Trump is going to let him making privilege claims on behalf of the administration suggests there is going to be an effort to suppress as much as possible. That is not what the situation calls for, and many are rightly skeptical of Barr's intent. If this was a democrat president, republicans would have impeached him or her already. Hell, they still want to lock Hillary up three years after Comey cleared her. Now, who's acting in bad faith?
