That's because the immigration status of his parents is irrelevant.
Explain to me how Kamala Harris was able to run for VP when the same language applies. Both her parents were immigrants and she was born in California.
In 2016, then Louisiana Governor, Bobby Jindal, ran for president in the GOP primary and both his parents were immigrants and he was born in Louisiana.
In order to run for office, one MUST meet the Constitutional requirements. The eligibility of the above individuals to run for President of the US has never been questioned since they met the "Natural Born Citizen of the United States" requirement.
First, three 'wrongs' don't make a 'right' {Hussein Obama, Kamala Harris, Vivek Ramaswamy}. I would welcome a Congress that would conform to our laws and remove the Presidency of Barak Hussein Obama from the history books, proclamations, laws, and whatever else a US President can taint of Americana, as his father was here on a visa, so he was subject to a foreign jurisdiction, as would his child be, Barak.
As for Harris, both her parents were here on passports subject to a foreign jurisdiction when she was born. Her father later matriculated from our immigration program and became a U.S. citizen. Even he says she is not a natural born citizen.
Vivek was born of parents here, but without a date of swearing in as US citizens, we have no idea of what jurisdiction, US or foreign, he was subject to when born.
