Amended. I doubt if we would repeal the entire 14th Amendment. And there is a procedure to do so. We need to redefine how citizenship is obtained.
There are congressmen who have suggested just that.
In fact, the congressmen have stated that the clause "All persons born or naturalized in the United States, and subject to the jurisdiction thereof," has been MISINTERPRETED to apply to any person born in the U.S. automatically becomes a U.S. citizen; however, they claim that when this was written, its intention was to assure that citizenship is bestowed only upon those people within whom U.S. JURISIDCTION resides....Specifically, I read that these words were put into place so that children born of people NOT UNDER THE JURISDICTION OF THE U.S., i.e., foreign diplomats, were NOT and could not be US citizens.....as the infant's parents WERE NOT UNDER U.S. JURISDICTION.
Illegal aliens, therefore, are also NOT UNDER U.S. jurisdiction, so their citizenship belongs to the country of the infant's parents.
But that can only apply to the future. Once someone is an American citizen via being born here, you cant redefine citizenship to take it away from them. Court wont allow that for same reason you cant be tried under a law that didnt exist until after a crime was committed.
