(WASHINGTON) — President Donald Trump attended oral arguments at the Supreme Court on Wednesday, a historic first for a sitting president, as the justices considered his executive order seeking to end birthright citizenship.
No cameras were allowed inside the courtroom. Trump’s motorcade arrived outside the building on Wednesday morning shortly before arguments began. His motorcade later departed the court after Solicitor General John Sauer’s presentation on behalf of the government.
After the hearing concluded, Trump wrote in a social media post that the U.S. is “stupid” to allow the practice.
“We are the only Country in the World STUPID enough to allow ‘Birthright’ Citizenship!” Trump posted.
According to the Pew Research Center, 32 other countries, most of them in the Western Hemisphere, have laws similar to the U.S. guaranteeing citizenship to children born in the country.
Trump, who entered the court at 9:47 a.m. wearing a red tie and blue suit, was seated in the front row of the public gallery alongside White House Counsel David Warrington, Attorney General Pam Bondi and Commerce Secretary Howard Lutnick.
As Sauer parried with the justices, Trump sat attentive and expressionless. His presence in the chamber was not publicly announced or acknowledged by any of the justices on the bench. Trump did not engage with anyone seated beside him or in the chamber.
Trump previously floated attending arguments last year when the court took up his global tariff policy, but ultimately he did not attend.
Trump has repeatedly attacked the Supreme Court in the wake of the ruling invalidating most of his tariffs, including two justices he appointed, Neil Gorsuch and Amy Coney Barrett.
“I love a few of them, I don’t like some others,” Trump said on Tuesday when asked which justices he would be listening for most closely.
Trump is asking the justices to uphold his Day 1 executive order eliminating birthright citizenship under a novel interpretation of the 14th Amendment and requiring parents to prove their own legal status before citizenship is granted to their children.
Lower courts have struck down Trump’s executive order.
American Civil Liberties Union Legal Director Cecillia Wang argued on behalf of the class of plaintiffs. Wang herself is a birthright citizen, born in Oregon to Taiwanese parents.
ACLU Executive Director Anthony D. Romero addressed Trump’s attendance, saying he will “watch the ACLU school him in the meaning of the Constitution and birthright citizenship.”
“Any effort to distract from the gravity and importance of this case will not succeed. The Supreme Court is up to the task of interpreting and defending the Constitution even under the glare of a sitting president a couple dozen feet away from them,” he said.
