My understanding, and this is the difference between the recording and the blues, is that the reason for the blues is that you actually have manual typing going on and there could be errors. In a recording, you're visually watching it. It's direct and obviously, there's no issue there.
When you're typing it, the people who spoke should have the ability to review what the transcript says to ensure that it accurately reflects what they said. Therefore, there's a time period in which those corrections can be made before it becomes public.
It seems to me that it should be limited to those who actually spoke in committee and to their personal staff. If there is an error and it does go out to anybody outside, there's an erroneous record that could be out there.
I would say that the blues should remain internal.
