Donald Trump took to social media on Wednesday to lash out over the longstanding, constitutionally enshrined right of birthright citizenship. He had attended a Supreme Court hearing to hear oral arguments on the legality of ending birthright citizenship, making him the first sitting President in history to do so.
“We are the only Country in the World STUPID enough to allow ‘Birthright’ Citizenship!” Trump wrote on his social media platform, Truth Social, after the oral arguments in the Supreme Court hearing had ended.
However, despite the President’s claim, birthright citizenship is the rule in dozens of countries, including America’s neighbors, Mexico and Canada. Meanwhile, birthright citizenship in the US was enshrined as a right in 1868 through the 14th Amendment to the US Constitution.

Meanwhile, Trump has long sought to eliminate birthright citizenship in the US. On his first day back in the Oval Office last year, he signed an executive order to challenge the longstanding citizenship rule.
The Supreme Court heard oral arguments in the case, titled Trump vs. Barbara, a challenge to the president’s January 2025 executive order seeking to change the Citizenship Clause of the 14th Amendment by ending birthright citizenship.
Meanwhile, when Trump attended the Supreme Court hearing, he became the first sitting US president to sit in on oral arguments. Trump stayed in the courtroom for around one hour in order to hear Solicitor General D. John Sauer defending his executive order.
By attending the hearing, Trump became the first sitting U.S. president to sit in on oral arguments before the Supreme Court. He stayed in the courtroom for about an hour to hear Solicitor General D. John Sauer defend Trump’s executive order. Trump left the hearing about 15 minutes after a lawyer for the American Civil Liberties Union began its case against the order, CNBC reported.
On returning to the White House, the president took to his Truth Social to voice his opposition to birthright citizenship, which allows children born to immigrants in the US in some situations.

Meanwhile, an analysis by the Pew Research Center found that 32 other countries in the world have birthright citizenship laws similar to those in the US, including Brazil, Canada, Mexico, Pakistan and Venezuela.
The option of birthright citizenship is normally automatic in the US, with the only exceptions being children born to foreign diplomats, born to foreign enemies with the US during a hostile occupation, or born on foreign public ships in US waters.
In the court on Wednesday, arguments partly centered on what constitutes being domiciled in the US. Meanwhile, Trump’s lawyers argued that undocumented immigrants are not in the US legally, they are not domiciled, nor do they pledge allegiance to the US. The lawyers said that their children should have no claims to US citizenship.

At the hearing, Supreme Court Justice Elena Kagan questioned why the Trump administration was trying to change the citizenship clause. “The text of the clause, I think, does not support you,” she told Sauer. “I think you’re sort of looking for some more technical, esoteric meaning.”
Moreover, Chief Justice John Roberts spoke on the subject, describing the “domicile” argument by Trump’s lawyers as “very quirky.”
Meanwhile, ACLU lawyer Cecillia Wang said the President’s executive order violated the 14th Amendment and could affect other laws. “The government’s rule, which really is looking at whether something has a divided allegiance because they’re a citizen of another country, would exclude the children of all foreign nationals,” Wang said.
