From Conservative Treehouse:
This is NOT the IG report on DOJ and FBI conduct about IG FISA abuses. This is a carve-out report, specific to James Comey and his leaked memos.
As part of the process, the inspector general report is previewed to James Comey in advance. According to John Solomon’s earlier reporting, Comey lawyers Patrick Fitzgerald and Daniel Richman, along with spokesperson Keith Urbahn all participated in his review of the report content. This is called the “Principal Review Phase”.
