Andrew Jackson clearly met the Constitutional requirement.

Article II, Section 1, paragraph 5 reads (in part):

No Person except a natural born Citizen, or a Citizen of the United States, at the time of the Adoption of this Constitution

Jackson was a US citizen in 1789, when the Constitution was adopted.

None of the founding fathers were natural born citizens. They couldn't be since they were born before the country existed.

[Wallace T.]

Jackson and Jefferson were born prior to the establishment of the United States, and were citizens at the time of its establishment, so they were eligible. As for the rest, the only one I am sure had a parent that was not naturalized was Chester Arthur. Like Obama, Arthur was ineligible to be President. If the others were naturalized, they would be in the same class as Donald Trump, whose mother was born in Scotland, but who was naturalized by the time he was born.

[Lurkinanloomin]

That part after the comma, “or a citizen at the time of this Constitution”, grandfathered in all the early Presidents because they knew that there could not be any natural born citizen of the USA for at least 35 years.

[Verginius Rufus]

Jefferson’s mother was born in England, but her father was a Virginia planter born in Henrico County, VA.
