Was thinking about the Dershowitz 302's he has and who would have obtained them. We all know that Rudy Guliani has been in Ukraine doing interviews and collecting info. What if Jeff Sessions made Rudy an unknown (undercover) special agent. This would give him the authority to be making 302's and turning over information to Barr (DOJ). When you look up special Agent this is something I found. Keep in mind the [GS] in Q's recent post we all were thinking George Soros but sometimes there are multiple meanings.

"Within the U.S. government, the title of special agent designates a general investigator in the GS-1810 job series, criminal investigator in the GS-1811 job series or a counterintelligence operations specialist in the GS-0132 job series according to the Office of Personnel Management (OPM) handbook. Special agents typically have an undergraduate degree."
