Several supporters of US President Donald Trump have called for restrictions on pregnant women travelling to the US.

The comments come after Mr Trump’s attempt to restrict birthright citizenship in the US was rejected by the US Supreme Court on Tuesday.

In response, Tom Homan, who Mr Trump appointed as “border czar”, said border security should be stepped up, as reported by The Guardian.

“Now, we step up enforcement”, he said.

“We step up more enforcement, even though we’re doing record amounts of enforcement now.

“We need to, you know, really buckle down on birth tourism.

“We have many investigations on birth tourism, but we need to triple, quadruple down on that”.

His comments were referring to pregnant women who travel to the US and give birth in the country as a way to acquire American citizenship.

Another Republican, Andy Ogles from Tennessee, echoed those sentiments and taking it one step further, saying he would introduce legislation to ban pregnant women from entering the country.

On Fox News, he discussed his “Anchors Away Act”.

“We are literally going to be dropping Anchors Away, which really pushes back against the Supreme Court, this idea that if you are pregnant and you are from a foreign nation, you know what, it is time for Congress to pass a law that says you cannot come here.

“You cannot have a baby on US soil and exploit this loophole.”

On Tuesday, the justices in a 6-3 ruling authored by conservative Chief Justice John Roberts decided that Mr Trump’s directive violated language in the US Constitution’s 14th Amendment that confers citizenship to those born in the United States who are “subject to the jurisdiction thereof”.

They upheld a lower court’s decision that blocked Trump’s executive order that had directed US agencies not to recognise the citizenship of children born in the United States if neither parent was an American citizen or legal permanent resident.

“Citizenship, then and now, was the right to have rights - to freely participate in our political community,” Chief Justice Roberts wrote, adding that the authors of the 14th Amendment extended that promise to every free-born person in the land.

“We keep that promise today.”

Following the ruling, Mr Trump took to Truth Social to say the ruling was “too bad for our Country, but we can easily make it up in Congress through Legislation, with the support of the President, that has now been determined during this process”.

Before the ruling, experts had estimated that Mr Trump’s directive could affect the legal status of as many as 250,000 babies born each year and could require the families of millions more to prove the citizenship status of their newborns.
