One person involved in the discussions said the target date for the report’s release has been Nov. 20, but another indicated that the Justice Department is unlikely to deliver it by then and that it is more likely to come after Thanksgiving because of the complicated and contentious mix of legal, classification and political issues at play…

Barr has spent weeks working on the declassification decisions, as Horowitz scrutinized large volumes of classified information to assess how the FBI launched and pursued the investigation and related cases, people familiar with the matter said. Like others, they spoke on the condition of anonymity because the report is not yet public.

But a number of key figures in the probe have yet to receive draft sections of the inspector general’s findings, suggesting that the public release is still at least a week away, according to people familiar with the matter. It is possible, too, that as draft language of the report is shared with different people, the entire process could become bogged down by disputes about the accuracy of certain passages.
