As just a point of my own curiosity, when asked what state he was born in, what does he say?
He simply states that he was born in Germany while his father was stationed there, anyone in the need to know, knows what that means-that he is a US citizen.
His BC states he is a US citizen born abroad. Physically he was born on Leighton Barracks, a (former) US installation in West Germany. His BC is recorded at the US Embassy, Frankfort; and Washington DC, but he was born within the FRG state of Bavaria.
As a child of an overseas serving military member, he is a native and natural born US citizen, just like CPT John McCain et al.
While many argue Blackstone and the French guy, citizenship follows blood line before it follows soil.
That is why the 14th is misinterpreted to include illegals dropping babies with illicit purposes on US soil. They are not under the “jurisdiction” of the US regarding loyalties, they are criminals stealing identity and the left/right statists smile, nod and look for a vote...
If a person can be drafted in the military, or vote, then they are under the “jurisdiction thereof”, not simply by required to follow civil law.
Remember, the 14th was drafted and passed post CW explicitly to encompass slaves and children of slaves as citizens. Reading more into it is illogical, but then we are dealing with illogical and bent folks.
