Mueller Report Part II "Where Law Ends: Inside the Mueller Investigation."

 "At least for posterity, I had all the [team] members ... write up an internal report memorializing everything we found, our conclusions, and the limitations on the investigation, and provided it to the other team leaders as well as had it maintained in our files," wrote Weissmann in "Where Law Ends: Inside the Mueller Investigation."  https://www.politico.com/news/2021/12/02/mueller-report-alternative-release-523703

The reference prompted the New York Times to submit a Freedom of Information Act request for the document in January and to follow up in July with a lawsuit in U.S. District Court in Manhattan.

Lawyers from the U.S. Attorney's Office in Manhattan told Judge Katherine Polk Failla in a letter Thursday that officials have figured out what document Weissmann was alluding to and have begun reviewing it for possible release.

"Since Plaintiff filed its complaint, Defendant has located and begun processing this record and intends to release all non-exempt portions to Plaintiff once processing is complete," Assistant U.S. Attorney Jennifer Jude wrote. "Defendant estimates that primary processing of the record will be complete by the end of January 2022 at which time Defendant expects to send the record to several other DOJ components for consultation."
