We finally have confirmation of a procedural process that allows us to anticipate the timing for public release of the FISA report from Inspector General Horowitz.

According to the Associated Press:

The Justice Department’s watchdog is nearing the release of its report on the early stages of the FBI’s Russia investigation, a document likely to revive debate about a politically charged probe that shadowed President Donald Trump’s administration from the outset. The inspector general in recent days has invited witnesses and their lawyers who were interviewed for the report to review portions of a draft this week and next, a critical final step toward making the document public, according to multiple people familiar with the process who insisted on anonymity to discuss it.

As part of that process, the people will have opportunities to raise concerns or suggest potential edits, making it unclear precisely when in the coming weeks a final version could be ready for release. Inspector General Michael Horowitz told Congress in a letter last month that he did not expect a lengthy review period and that he intended to make as much of the report public as possible, with minimal redactions.

Generally speaking, and using the 2018 IG report on FBI conduct as a guide, the ‘Principal Review’ phase under Horowitz usually lasts 10 business days, or two weeks. All principals, and lawyers who review the report, are required to sign non-disclosure agreements.

Presuming this is principal review week one (seems certain), that would put the final report publication after the week of November 25th through November 29th. [NOTE: Thanksgiving day is November 28th]

The inspector general may allow principal comments to be added to the final report; however, the IG usually adds rebuttal information for any principal additions. Once the principal review and final OIG referencer check is complete the report moves to publication and public distribution.

In the example of the 2018 report on FBI conduct in the Clinton investigation, the principal review was 10 days from start to finish. It seems like Horowitz is following the same schedule. With Thanksgiving on Thursday November 28th, it is likely the resport will be released the week after Thanksgiving week; however it is possible for the report to be released during Thanksgiving week if IG Horowitz limits principal additions.

Best guess is the week after Thanksgiving.
