If you aren't convinced by the press secretary tweet inviting Space Force into the briefing room,
Consider this:
Jen flat out states that she doesn't know who is the point of contact at Space Force for the admin.
**"I am happy to check with our Space Force point of contact. I'm not sure who that is?? I will find out." Jen Psaki **

Doesn't sound like something the spokesperson for the commander in chief of the Space Force would say.
Really. I have never been so impressed with someone's professionalism, as I was seeing her in action!
