I concur that there is room to explore this in greater detail at the subcommittee.
I have one quick point on the motion, part 1(c). It's food for thought. It refers to briefings concerning national security. If the challenge is to protect conversations around national security, why is it limited to briefings? It could be that the next day we're having a follow-up discussion on a briefing. It's no longer a briefing, but the import of national security is still very much there. I think it's a fairly broad scope.
Those kinds of things should be discussed in greater detail at the subcommittee I think.
