As Nikki Haley surges in Republican polls, former President Donald Trump has turned to his social media outlet where he is promoting a "birther" conspiracy theory against the former South Carolina governor.

While her parents became citizens after her birth, Haley was born in South Carolina. Under the 14th Amendment of the U.S. Constitution, being born in the United States makes her a natural-born citizen. She is therefore eligible to become president.

The Trump campaign has long said that he would target whoever was most threatening him in the Republican primaries. Haley has emerged as his top rival in recent weeks. A new University of New Hampshire/CNN poll shows Haley trailing Trump in the Granite State by just single digits.

This is not the first time, Trump has raised birther claims. For five years, Trump routinely questioned former President Barack Obama's birthplace – a lie that many saw as a racist dog whistle.

The Haley campaign did not respond to requests for comment.

Famously, Trump also has a parent born outside of the U.S. His mother, Mary, is from Scotland.
