They’re not using it for the document per se, they’re using it to show that he knew he shouldn’t show classified or sensitive documents to people but did it anyway and that he didn’t declassify everything he took. Also, if they don’t have the document, that he either still has it or destroyed it - or, I guess, he was lying on the tape, although that wouldn’t be criminal
Leaking classified information is illegal???? Who knew? If that's the case, everyone who was involved in leaking the Steele Dossier to the press and people on the Hill will be in REALLY big trouble. /s I wish we could invent a truth serum that would induce all the reporters to come clean on who has leaked classified information to them over the years. Throw them all in jail. Official Washington would be a ghost town.
