The situation room would have no classification imo. Based on what was being discussed would require clearance and the need to know. I don’t know if is is a SCIF, but I would doubt it. The ban on devices is probably upheld there. So Omarosa could be in there and fired there or its vicinity.
I’m looking more toward action against media outlets that might play it on air or publish a transcript.
We know that Eric The Red let the NYT get away with it. Sessions might not? Or, at a minimum, send a shot across their bow?

The fact that the recording exists is shocking; that it allegedly happened in the most secure room in the White House — known as a SCIF (Sensitive Compartmented Information Facility) — would represent a violation of strict internal procedures prohibiting unsecure devices there. The goal of these rules, of course, is to ensure that no external devices can be used by foreign enemies or spy services to listen in or record sensitive information.
