IIRC the Federal courts have consistently upheld the concept of “birthright citizenship”. IIRC it’s connected somehow to the 14th Amendment.
The court’s have “interpreted” it that way, but it’s a false interpretation.
They consistently ignore “and subject to the jurisdiction thereof”.... which means that just because you were crapped out on US soil, you are NOT a citizen at birth. But the courts have “interpreted” it to mean that every illegal crapped out is a citizen entitled to YOUR benefits.
All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the state wherein they reside.
