Trump warns Supreme Court ruling on birthright citizenship could prove 'a disaster' as decision nears

President Donald Trump took direct aim at the Supreme Court on Thursday, predicting the justices will likely rule against his executive order restricting automatic citizenship for certain children born on American soil, and warning the consequences will be severe.

"This decision by the Supreme Court is a very big one. They'll probably rule against me because they seem to like doing that," Trump said from the Oval Office, as Fox News Digital reported.

The remarks came as the nation's highest court prepares to hand down its ruling in the coming weeks on Trump's January 2025 executive order, which sought to limit automatic citizenship for some children born in the United States. The case has become the most consequential constitutional fight of Trump's second term, and the president is not waiting quietly for the outcome.

Trump's case: The 14th Amendment was never meant for this

Trump framed his argument in historical terms, tying the citizenship clause of the 14th Amendment directly to its post-Civil War origins. His language was blunt.

"This was not meant for Chinese billionaires to have their children become citizens of our country. This was meant, or other rich people, poor people. This was meant for the babies of slaves."

He pressed the point further:

"This was signed... right after the Civil War. You look at the dates, the dates alone, immediately after, this was having to do with the babies of slaves, and people have used it. And if this is allowed to stand, it will be a disaster economically for our country."

The Trump administration has argued that the current reading of birthright citizenship creates incentives for illegal immigration and has been exploited by so-called "birth tourism" operations, arrangements in which foreign nationals travel to the United States specifically so their children will be born as American citizens.

Trump put a number on the stakes. He claimed that 20 to 25 percent of people entering the country will gain entry through birthright citizenship and that the costs "are, I don't even think they're doable." He also pointed to a separate, recent tariff decision that he said will cost the United States $149 billion, a figure he cited to underscore what he sees as a pattern of economically damaging rulings.

Oral arguments exposed the fault lines

The Supreme Court heard oral arguments in April, and the session revealed deep skepticism from justices across the ideological spectrum. Chief Justice John Roberts and Justice Amy Coney Barrett both questioned whether the president's executive order complies with the citizenship clause of the 14th Amendment. Barrett reportedly warned that investigating citizenship under the new framework would create chaos.

Justice Ketanji Brown Jackson offered perhaps the most vivid line of the day:

"Are we bringing pregnant women in for depositions?"

Trump attended those oral arguments in person, a move Fox News Digital described as the first known time a sitting president sat in on Supreme Court oral arguments. The gesture itself signaled how seriously the White House views this case.

Yet the questioning from Roberts and Barrett, both appointed by Republican presidents, suggested the administration faces long odds. The constitutional text at issue, Section 1 of the 14th Amendment, has been read for more than a century to guarantee citizenship to virtually all persons born on U.S. soil. Rewriting that understanding by executive order, rather than through a constitutional amendment or congressional action, is a heavy legal lift.

A legal scholar's warning

University of California Berkeley law professor John Yoo, a conservative legal voice who served in the George W. Bush administration, previously told Fox News Digital that he expects the Supreme Court to overrule the Trump birthright order. But Yoo did not dismiss the underlying policy concern. He offered an alternative path forward:

"The better way to operate under the current constitutional rule of birthright citizenship is to more vigorously enforce visas and to shut down businesses that encourage and enable birth tourism."

That distinction matters. Yoo's argument is not that the problem Trump identified is imaginary. It is that the executive order chose the wrong tool to fix it. If the Court agrees, the administration will need Congress, or a different enforcement strategy, to address birth tourism and the broader incentive structure that automatic citizenship creates for illegal border crossings.

Public opinion has shifted, against Trump's position

The political terrain on this issue has changed dramatically. A Fox News Poll found that 69 percent of voters now support birthright citizenship for children born in the United States to illegal immigrants. That figure stood at just 45 percent when Fox News first polled the question in 2006.

A 24-point swing in two decades is a significant shift, and it complicates the political calculus for the administration. Trump's executive order may resonate with his base, but the broader electorate, at least as measured by this poll, has moved in the opposite direction.

Still, polls measure sentiment, not constitutional law. The question before the Court is not whether birthright citizenship is popular but whether the president can redefine it unilaterally. Those are very different questions, and the answer to the second one appears likely to be no.

Trump's frustration with the Court

The president did not confine his criticism to this single case. He said plainly that he is "not happy with some of the decisions" the Court has issued, framing the birthright case as part of a broader pattern.

"It would be a disgrace if the Supreme Court of the United States allows that to happen. Remember what I said, 20 to 25% of the people coming into our country will come in through birthright citizenship."

Fox News Digital reached out to the Supreme Court for comment. No response was noted.

Demonstrators gathered outside the Supreme Court in Washington, D.C., on April 1, 2026, reflecting the intensity of public interest in the case. The fight has drawn attention from immigration hawks, civil liberties groups, and legal scholars who see the outcome as a potential landmark, one way or the other.

The real failure isn't at the Court

If the justices do strike down Trump's order, the president's frustration will be understandable. But the deeper failure belongs to Congress. For decades, lawmakers on both sides have ducked the birthright citizenship question. They have refused to pass legislation clarifying the scope of the 14th Amendment's citizenship clause, refused to crack down meaningfully on birth tourism, and refused to close the loopholes that the administration now says cost the country billions.

Trump tried to do by executive pen what Congress would not do by statute. The Constitution may not allow that shortcut. But the underlying problem, a citizenship framework being exploited in ways its authors never imagined, does not vanish because the Court says the president picked the wrong instrument.

The ruling will land in the coming weeks. If it goes the way Trump expects, the question shifts back to Capitol Hill. And if history is any guide, that is where it will sit, untouched, for another generation.

Washington's favorite move is to let the courts say no, and then blame the courts for the mess Congress refused to clean up.
