The New York Times filed a Freedom of Information Act request for the document in January, and then filed a lawsuit in July.
Lawyers from the U.S. Attorney's Office in Manhattan wrote a letter to Judge Failla on Thursday saying that they had figured out what document Weissmann was referring to and had begun reviewing it for possible release.
"After the complaint has been filed, the defendants have begun processing the record and intend to release all non-exempt portions to the person who filed the complaint," Jude wrote. "Defendant expects to complete primary processing of the record by the end of January 2022."
Jude proposed updating the court by mid-February, but did not give an estimate of how long those consultations would take.
The pledge to process the alternative report is not a guarantee that it will contain new revelations. The Justice Department can use a variety of exemptions to the Freedom of Information Act to shield parts of the document. Due to legal restrictions, it is more difficult to release grand jury information from the DOJ.
The group Weissmann supervised in the special counsel's office was called "Team M", after its primary target. Team R was more focused on the ties between Russia and Donald Trump.
It's not clear if other investigative teams also prepared compilations that weren't in the final report.
