President Donald Trump said he plans to be present at the Supreme Court on Wednesday as justices hear oral arguments in Trump v. Barbara, a case that could determine whether children born in the United States to illegal immigrants and foreign visitors are entitled to birthright citizenship under the Constitution.

Speaking about the upcoming hearing, Trump indicated his intention to attend in person. “I’m going,” Trump said when asked about SCOTUS hearing oral arguments in the case on April 1. “I think so, I do believe because I’ve listened to this argument for so long.”

Trump reiterated his criticism of how birthright citizenship is currently applied, pointing to cases involving wealthy foreign nationals. “Chinese billionaires and billionaires from other countries who all of a sudden have 75 children or 59 children in one case or 10 children, becoming American citizens,” Trump said. “[The 14th Amendment] was about slaves … all of this legislation, all of this having to do with birthright citizenship, it was at the end of the Civil War. The reason was, it had to do with the babies of slaves and the protection of the babies of slaves.”

He continued to argue that the policy has strayed from its original purpose. “It didn’t have to do with the protection of multi-millionaires and billionaires wanting to have their children getting American citizenship,” Trump continued. “It is the craziest thing I’ve ever seen.”

Shortly after returning to office last year, Trump signed an executive order aimed at ending automatic citizenship for children born in the U.S. to illegal immigrants and foreign tourists, often referred to as “anchor babies,” a term used to describe children whose citizenship can later enable family members to obtain legal status.

Following the order, advocacy groups filed lawsuits challenging the policy, ultimately bringing the case before the Supreme Court, where a final decision is expected this year.

Data from 2023 estimated that between 225,000 and 250,000 children were born in the United States to illegal immigrant parents, accounting for roughly seven percent of all births that year.

The Supreme Court has not issued a definitive ruling explicitly requiring that children born in the U.S. to illegal immigrants must be granted citizenship, and the issue remains the subject of ongoing legal debate.

A number of conservative legal scholars argue that the Citizenship Clause of the 14th Amendment does not mandate birthright citizenship in such cases, maintaining that children born to individuals without legal status are not “subject to the jurisdiction” of the United States as that phrase was originally understood.
