3. He does know... they all know

That's why they don't push it by taking it to court.

There have been dozens of such cases already this year where Democratic members show up and demand entry (often displaying their congressional credentials) only to be turned away. It's a useful visual and it's great fodder for these types of clips. "What are they trying to hide" (etc.) - but they don't take it to court because they know they can't win.

Just like they'll send sternly worded letters demanding documentation or responses to questions with deadlines to respond... and then the next time that executive branch officer is testifying before Congress they'll ask pointed questions about why they didn't get a response to their oversight... while the witness tries to avoid the question.

But it's all for the cameras without any substance beyond the implied threat of what will happen when we next have the majority.

The court precedents go all the way back to the founding era (indeed into British rulings in the decades prior). Legislative bodies act by votes of the majority. They can delegate powers to groups or even individuals... but only by such acts. Individual members cannot wield the powers of the legislative branch without it.
