I always enjoy your deciding votes, Madam Chair.
To me, it comes down to courtesy towards our guests. Even if we have the ability to summon initially versus ultimately—certainly we could ultimately—I think the messaging is better, more thoughtful, and shows more respect to our guests when we do it that way. I absolutely agree with how Pat Martin is discussing it and Chris initiated it. I think this should be a request. I'd be frankly very disappointed if they wouldn't attend to this committee's request, but we have the ability to respond, if they don't.
Regardless, what moves this along is simply to extend the invitation. I'm not going to beat my gums on this one, but I think a request is the proper way and shows proper form, regardless.
