It is unclear how much will be redacted from the documents that will be released---and if all the documents will actually be released.

At this point, things are still in flux. While we continue to plan for an online release by the deadline, it is unclear what will be part of the release. In regards to any possible postponement requests, because agency appeals are not public, we cannot share that information.-RW
