Tomorrow the Supreme Court hears oral argument in Trump v. Barbara — the merits challenge to Executive Order 14160 on birthright citizenship — and I want you to walk in knowing exactly why the Trump administration’s constitutional argument is the correct one, not just politically defensible but historically airtight.
What the Text Actually Says
Start with the words. The Fourteenth Amendment, ratified in 1868, provides:
“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.”
There are two conjunctive requirements. Birth on American soil is not enough. You must also be subject to the jurisdiction thereof. The progressive reading simply erases that second clause. My read, and I think the correct read, is that the text means exactly what it says.
The 1866 Rosetta Stone
Here is the history that unlocks the whole debate. Two years before the Fourteenth Amendment was ratified, Congress enacted the Civil Rights Act of 1866. Its purpose was to guarantee that freed African-American slaves — people the Dred Scott decision had declared non-citizens — would be recognized as full citizens going forward. The key language:
A citizen is one born in the United States who is “not subject to any foreign power.”
Congress used that statute to codify citizenship, but members quickly realized a statute could be repealed by a future Congress or might not constitutionally override Dred Scott. So they elevated the principle into the Constitution itself. The phrase “subject to the jurisdiction thereof” in the Fourteenth Amendment is a direct constitutional translation of the 1866 Act’s “not subject to any foreign power.” The two phrases are synonymous. They were designed to be synonymous. Senator Jacob M. Howard of Michigan, who introduced the Citizenship Clause language on the Senate floor, said as much at the time.
So what does “not subject to any foreign power” mean for a child born to illegal aliens? It means the parents — and by extension the child — owe their primary allegiance elsewhere. They are subject to a foreign power. The second Fourteenth Amendment prong is not satisfied.
The Native American Proof Point
There is a historical example that makes this concrete. From 1868 through the early twentieth century, a substantial population of people were born on American soil yet were not American citizens. They had to follow American law — they stopped at traffic signals, so to speak — but they were not subject to the jurisdiction of the United States in the constitutional sense because their allegiance ran to their tribal nations, which courts treated as foreign sovereigns.
I am talking about Native Americans. It was not until Congress enacted the Indian Citizenship Act of 1924 — the Snyder Act — that Indigenous people born in the United States were formally granted citizenship by statute. Why did that statute have to exist at all if mere birth on American soil were sufficient? Because it was not. The Fourteenth Amendment’s framers understood “subject to the jurisdiction thereof” to exclude those owing allegiance to a foreign power, including tribal nations. The Native American example is not a counterargument — it is proof of the original meaning.
The Standing Puzzle — And How Trump Solved It
One question I hear constantly is: if this interpretation is so obviously correct, why has it never been litigated to resolution?
The answer is standing. Article III of the Constitution limits federal courts to actual “cases and controversies.” To sue, you must be injured. Before Trump’s executive order, the only people directly affected by birthright citizenship policy were the children of illegal aliens and foreign nationals — people who benefited enormously from the existing interpretation. Why would they sue? They would not. And the Americans who objected could not demonstrate the kind of direct, concrete injury Article III requires.
Trump’s executive order changed the arithmetic. Once the administration stopped issuing citizenship documents to children born of illegal aliens and tourists, those families and their advocacy organizations were injured and had standing to sue. That is how these cases finally reached the Supreme Court. Credit the administration for engineering a justiciable controversy where none had existed.
The Second Amendment Connection
None of this is abstract to those of us who care about the right to keep and bear arms. Virginia alone has roughly 1.2 million foreign-born residents, many with no cultural connection to the constitutional traditions that produced the Second Amendment. That demographic reality is part of why blue-state legislatures keep reaching for so-called “assault weapon” bans and magazine restrictions. If you systematically replace the existing population with people who have no heritage in American constitutional rights, you should not be surprised when those rights erode. This case is downstream of that larger fight.
My read is that the Trump administration has the stronger textual and historical argument. Whether the Court agrees is another question — these things are never certain. But walk into tomorrow’s argument knowing the text, knowing the 1866 Act, knowing the Native American precedent. That is the honest constitutional picture.
