It seems pretty on-brand to be honest though, I wonder why that rule exists and what benefit it provides. The first couple presidents couldn't have met it, so I wonder when it was introduced.

"No Person except a natural born Citizen, or a Citizen of the United States, at the time of the Adoption of this Constitution, shall be eligible to the Office of President"
The first few presidents were citizens of the US when the Constitution was adopted (previously, the US had been governed by the Articles of Confederation.)
The first American born president (born after the revolution) was Van Buren, the first 7 were born British citizens!
> No Person except a natural born Citizen, or a Citizen of the United States, at the time of the Adoption of this Constitution, shall be eligible to the Office of President;
Hamilton was a citizen at the time of the Constitution’s adoption and was therefore eligible to run for president should he have been so inclined.
Van Buren was born in NY, in the US, but was the only president that used English as a second language. Both of his parents were of Dutch descent.
"No Person except a natural born Citizen, or a Citizen of the United States, at the time of the Adoption of this Constitution, shall be eligible to the Office of President" from section 1, Article 2 of the US Constitution (adopted 1789).
There is some legal debate about what "natural born Citizen" means now, but that has not fully been testing in court IIUC.
There’s two sources of law for determining citizenship though: 1. The Constitution and 2. Laws that Congress passes. If you’re born a citizen according to either of these sources, congrats, you’re a natural born citizen.
I have no idea about Thiel's specific case, and it doesn't seem like there's any info about it online.
