A passport also serves as documentation of citizenship, and Cruz has a passport and has had one for a long time.

Is citizenship the issue? Or is ‘natural born citizenship’?
Having the passport or the CRBA doesn’t settle either of those issues. They are interchangeable, though, when documenting citizenship. The NBC question is a matter for the courts, and the CRBA/passport doesn’t address that it all. It just says you’re a US citizen.
the latter, however I would not put it past him to have fraudently obtained the one he has using his “I am the face of God” card.
