Asking research committee about on-campus interview
I would wait for a few more days, actually. You don't want to seem too eager. If you are high on the list, you may still need to negotiate a few things, and it is better to be a bit calm about it. Let them come to you. 

It is what it is, of course. 

But if you have other decisions to make immediately, then you may need to ask now. Otherwise, patience is suggested.
