Congress has already said through enacted immigration law who does not need to be naturalized and is therefore already a citizen at birth.

Did I not read in your posts that Congress has been known to change those rules from time to time, and that it is within their sphere to define?

[BuckeyeTexan]

Yes, you did and it is. (For those born abroad to Americans. This child was not born to Americans. McCain and Cruz were.)

[Ray76]

“A person born out of the jurisdiction of the United States can only become a citizen by being naturalized, either by treaty, as in the case of the annexation of foreign territory, or by authority of congress, exercised either by declaring certain classes of persons to be citizens, as in the enactments conferring citizenship upon foreign-born children of citizens, or by enabling foreigners individually to become citizens by proceedings in the judicial tribunals, as in the ordinary provisions of the naturalization acts.” - U.S. v. Wong Kim Ark

A person born out of the jurisdiction of the United States can only become a citizen by being naturalized,
