US President Donald Trump, known for his anti-immigrant stand, now wants to end birthright citizenship.

In an interview with Axios, a new four-part documentary series debuting on HBO this Sunday, Trump said that he wants to end the constitutional right to US citizenship for children born in the country to non-citizens and unauthorised immigrants.

“We’re 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 for 85 years with all of those benefits,” Trump said during the interview.

“It’s ridiculous. It’s ridiculous. And it has to end,” the US President, known for his aggressive rhetoric, said.

“It was always told to me that you needed a constitutional amendment. Guess what? You don’t,” he went on saying during the Axios interview.

Trump asserted, “You can definitely do it with an act of Congress. But now they’re saying I can do it just with an executive order. It’s in the process. It’ll happen . . . with an executive order.”

According to reports, Trump is planning to sign an executive order to put in force his plan.

But legal experts say that the decision runs afoul of the Constitution and, if implemented, would be the most aggressive yet by any US President.

Trump’s recent comment comes just ahead of next week’s midterm elections. The US President has already intensified his pledge to take a hard line on immigration.

The 14th Amendment guarantees that children born in the US have a right to US citizenship. Amended 150 years ago, the text reads: “All persons born or naturalized in the United States and subject to the jurisdiction thereof, are citizens of the United States.”

Several other countries, including Canada, have a policy of birthright citizenship.

Trump didn’t specify any timeframe for such an order. It is, however, noteworthy that some of his previous statements on using executive action have not been fulfilled.

According to CNN, the President had during an interview with Fox News said that he would construct tent cities to house migrants travelling through Mexico to the US southern border.

His comment comes as a massive wave of immigrants from some Latin American countries traverse through Mexico to reach the US border, where Trump’s administration has deployed 5,200 troops to stop the immigrants from entering the country.

Trump had previously attempted to bar entry to citizens from some Muslim-majority countries.
