"Because the Addendum includes sensitive information about ongoing investigations, the government is seeking to partially seal the Addendum, and has filed publicly a redacted version of the document that excludes the sensitive information," the document says.
The "sensitive information," of course, is what everyone wants to know! What has Flynn told Mueller about his interactions with the Russians and about the possibility that someone -- or someones -- on the Trump campaign colluded with the foreign power during the course of the campaign?
We don't get that full story here. It's like Mueller gets right to the good section of the book and then slams the cover shut.
Here are the five juiciest redactions from the Flynn sentencing document, with some context and a smidge of informed speculation about What It All Means.
So ... there is ANOTHER investigation. Not the Russia investigation and not the "criminal investigation." A third investigation! That certainly seems to be what is listed after the words "the campaign of Donald J. Trump" and the comma, right?
Interactions between the Trump team and Russia during the transition, you say? Who? When? And the redacted portion after the comma suggests that Flynn provided other information on the behavior of people on the presidential transition team during that crucial period of time.
This is the blank-check redaction of all blank-check redactions. Information concerning what? Who? When? And how? This is a 3-paragraph redaction that appears to have at least one sub-heading. So it's a substantial, um, something. What? I wish I knew!
