Nadler and crew seem to be on a find-a-crime shopping spree, but I'd bet all these names are all individual trojan horses designed to bring all the evidence to the table.
They tossed out a big net requesting all those documents, but they're betting they'll haul a bunch of evidence to prove their case, but in reality they'll likely haul a bunch of dirt on their own team which will be admissable and parallel construction for the MAGA team.
Remember Red October when the torpedo turns on the Russian sub that launched it? "…You killed us…"
Just a guess. kek
