President Trump has announced in an interview that he is considering signing an executive order to end birthright citizenship. The immigration loophole has been a controversial aspect of immigration reform, and one that Trump thinks needs to be closed. This will certainly trigger legal challenges with the Supreme Court likely being the final arbiter.

According to Fox News:

President Trump said in a newly released interview he plans to sign an executive order ending so-called “birthright citizenship” for babies of non-citizens born on U.S. soil — a move that would mark a major overhaul of immigration policy and trigger an almost-certain legal battle.

Birthright citizenship allows any baby born on U.S. soil to automatically be a U.S. citizen.

The policy, which stems from a disputed but long-recognized interpretation of the 14th Amendment, has given rise to what Trump considers abuse of the immigration system. Trump told “Axios on HBO” that the U.S. is the only country in the world “where a person comes in and has a baby, and the baby is essentially a citizen of the United States … with all of those benefits.”

Despite Trump’s claim, the U.S. is not the only nation to have birthright citizenship, but the policy is rare outside of the Americas. Trump called birthright citizenship “ridiculous” and said that “it has to end.”

The current policy considers anyone born on U.S. soil, regardless of the status of their parents, to be a U.S. citizen. Many legal scholars argue that this type of change would require a constitutional amendment and not just an executive order. However, it looks like President Trump will pursue the executive order.
