WASHINGTON, D.C. – The Capitol is buzzing about Supreme Court Justice Jackson’s childish explanation and defense of birthright citizenship after the United States Supreme Court opened its doors for oral arguments in Trump v. Barbara — a landmark case that could fundamentally redefine what it means to be an American citizen.
The case is the second time the nation’s highest court has heard arguments about birthright citizenship, although truly only the first time it has done so in earnest. In an extraordinary and almost theatrical moment, President Donald Trump attended the oral arguments in person — a highly unusual move from a president who has repeatedly suggested the majority-conservative court should rule in his favor.
At the center of the legal battle is a single, loaded phrase tucked into the 14th Amendment of the U.S. Constitution: “subject to the jurisdiction thereof.” The 14th Amendment states: “All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside.”
It is the kind of case that demands the sharpest legal minds in the country. But one exchange during the proceedings sent shockwaves far beyond the marble walls of the Supreme Court — and straight into the global news cycle.
Justice Ketanji Brown Jackson Comment Broke the Internet
Liberal Supreme Court Justice Ketanji Brown Jackson faced viral backlash from conservatives over a comment during oral arguments about birthright citizenship, where she floated an analogy comparing the issue to stealing a wallet in Japan.
In her own words, Jackson explained her thinking to the courtroom: “I was thinking, you know, I’m a U.S. citizen and visiting Japan, and what it means is that, you know, if I steal someone’s wallet in Japan, the Japanese authorities can arrest me and prosecute me.
Its allegiance means they can control you as a matter of law. I can also rely on them if my wallet is stolen, to, you know, under Japanese law, go and prosecute the person who has stolen it. So there’s this relationship based on, even though I’m a temporary traveler, I’m just on vacation in Japan, I’m still locally owing allegiance in that sense.”
The analogy was intended to illustrate how even a temporary visitor remains “subject to the jurisdiction” of a foreign country — and therefore, by extension, how babies born in the U.S. to non-citizen parents could still be considered subject to U.S. jurisdiction under the 14th Amendment. The internet, however, was having none of it.
Conservative Backlash: “I Cannot Believe This Woman Is on the Court.”
The reaction from conservatives was immediate, fierce, and deeply personal.
Conservatives and Republican politicians quickly seized on Jackson’s comment equating territorial jurisdiction with political allegiance, arguing that her analogy fundamentally misreads the 14th Amendment’s birthright-citizenship clause.
“I don’t think KBJ knows what words mean,” conservative communicator Steve Guest posted online.
Turning Point USA’s Andrew Kolvet wrote: “Leave it to Justice Jackson to defend the suicide pact of birthright citizenship for illegals by not understanding the difference between territorial jurisdiction (obeying local laws), and political allegiance. If territorial jurisdiction means allegiance, every tourist is a US citizen, which is insane. The whole thing is so low IQ and embarrassing for the Court.”
Florida Governor Ron DeSantis summed up his feelings in three words: “Oh, good grief, come on now!”
Perhaps the most biting critique came from journalist Miranda Devine, who pointed out a glaring flaw in Jackson’s choice of example country. “Not sure if she’s aware but of all the countries to mention, Japan is probably the least helpful to her cause,” Devine wrote. “Babies born in Japan can only become citizens if they have Japanese blood and are born to registered Japanese citizens whose names appear in a special book.”
In other words, Japan — the very country Justice Jackson chose to illustrate inclusive territorial jurisdiction — operates one of the most restrictive birthright citizenship systems in the developed world.
“I cannot believe this woman is on the court, and I cannot believe anyone on the left thinks letting her air these thoughts out loud does them any favors,” wrote Real Clear Investigations senior writer Mark Hemingway.
What Justice Jackson Was Actually Arguing
To be fair to Justice Jackson, the wallet analogy was not her only contribution to the day’s proceedings. She also pressed the Trump administration on the deeply practical consequences of the executive order it was defending.
Jackson was more direct on the question of enforcement: “Are we bringing pregnant women in for depositions? How do we figure this out?” she asked incredulously.
Solicitor General Sauer responded that the government would likely issue Social Security numbers to every baby but then figure things out afterward.
Jackson’s broader legal point, while awkwardly expressed, was not without merit. She argued that the phrase “subject to the jurisdiction thereof” has long been understood to mean the exclusion only of the children of diplomats — and that any American would be subject to the jurisdiction of a foreign country while traveling there. The wallet-in-Japan scenario was meant to illustrate this concept.
Justice Alito and Justice Jackson had also earlier offered a possible explanation for the court’s use of the term “domicile” in a key 19th-century precedent, suggesting that the original ruling had wanted to help the public accept the outcome by emphasizing that the plaintiff’s parents were settled members of society.
A Landmark Case With Enormous Consequences
Whatever one thinks of Jackson’s analogies, the stakes of this case could not be higher.
Trump’s executive order, signed on January 20, 2025, would end birthright citizenship — the guarantee of U.S. citizenship to virtually everyone born in the country. The order ended birthright citizenship for the children of undocumented immigrants, as well as those of immigrants who are in the United States legally but temporarily, for example, on a student or work visa.
The consequences of the executive order going into effect would be enormous. It would prevent about a quarter-million children each year from gaining citizenship going forward. It would also mean that every family that gives birth to a child — that’s 3.5 million families a year — would have to prove their ancestry and lineage before their child would be recognized as a citizen.
An estimated 2.7 million additional people would be unauthorized by 2045, and 5.4 million additional people by 2075, according to projections published by the Migration Policy Institute and Pennsylvania State University.
How the Court Appears to Be Leaning
Despite the controversy over Justice Jackson’s comments, the broader picture from oral arguments was relatively clear.
Nearly every member of the court expressed skepticism of the administration’s revisionist version of a long-established and core American principle. The skepticism was notably bipartisan.
Justice Neil Gorsuch noted that the Trump executive order focuses on parents, but the 14th Amendment focuses on birthright for the child. Justice Amy Coney Barrett questioned the practicality of the Trump proposal, asking: “How would you adjudicate these cases? You’re not going to know at the time of birth whether they have the intent to stay or not, including U.S. citizens by the way.”
Solicitor General Sauer argued that, contrary to the law as understood for 160 years, the 14th Amendment does not confer automatic citizenship on every baby born in the U.S., and that the true meaning of the amendment was to grant citizenship to former slaves and their children, no more.
The ACLU’s Cecillia Wang pushed back forcefully, arguing that “We can’t take the current administration’s policy considerations into account to try to re-engineer and radically re-interpret the original meaning of the 14th Amendment.”
The Supreme Court is expected to issue its ruling in the coming months. The decision will shape not only the legal identity of hundreds of thousands of children born on U.S. soil each year, but will also signal how far the current court is willing to go in reinterpreting constitutional provisions that have stood unchallenged for over a century.
As for Justice Ketanji Brown Jackson, her wallet will be remembered long after the ruling is handed down.
Whether she meant to or not, in searching for a simple, relatable analogy to defend one of America’s most foundational legal principles, she may have inadvertently handed her opponents their most memorable line of the entire debate.
