NIKKI HALEY IS NOT ELIGIBLE TO BE PRESIDENT
Nikki Haley was born in South Carolina and became a U.S. citizen at birth. She is over 35 years old and has been a resident of the United States for more than 14 years.
President Chester Arthur was the son of an Irish citizen who was not naturalized American until more than a decade after Arthur became President. President Barack Obama's father was not an American citizen. Chester Arthur was Vice President as the son of an alien. Vice President Kamala Harris was born to two aliens.
Parentage is irrelevant to the citizenship of a child born within the territory and jurisdiction of the United States unless the parent confers diplomatic immunity to United States laws.
Article II
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; neither shall any person be eligible to that office who shall not have attained to the age of thirty five years, and been fourteen Years a resident within the United States.
The issue of Natural Born Citizen has NEVER been litigated.
