President Trump escalated his fight over the stalled White House East Wing Ballroom late Friday, calling the National Trust for Historic Preservation "treasonists" and accusing the nonprofit of exposing classified military secrets, hours after his administration asked the Supreme Court to let construction resume.
The broadside, posted across multiple Truth Social messages Friday evening, came after two federal courts sided with the preservation group and ordered ballroom construction halted. Trump's Solicitor General, D. John Sauer, filed an emergency petition arguing the project is "vitally required by national security," the Washington Examiner reported. The Supreme Court has not yet acted on the request.
The legal fight traces back to December 2025, when the National Trust sued the Trump administration over the East Wing construction, arguing the president did not follow proper regulatory or authorization channels. A federal district court in Washington, D.C., ruled against the administration. A federal appeals court upheld that decision and went further, holding that congressional approval was required before the project could move forward. Both courts, however, allowed underground bunker construction beneath the ballroom site to continue.
In his Friday night posts, Trump framed the lawsuit as a direct threat to presidential security. He alleged that U.S. military officials and the Secret Service showed the National Trust detailed plans and specifications for the facility and asked the group not to file suit, a request he said they ignored.
Trump posted on Truth Social:
"They were asked by the United States Military not to bring this suit because of the Top Secret nature of the important facility being built. They were shown detailed plans and specifications of this knitted, unified, and cohesive structure by Top Officers and Leaders in both the Military and Secret Service. But this did not deter them because they suffer from Trump Derangement Syndrome."
In a separate post, he wrote that the group was "trying to stop one that is vital to our National Security, and the Safety of all Presidents of the United States, both current and future, their families, staff, and Cabinet members."
Those claims remain unverified by any independent source. The National Trust has consistently denied that its lawsuit endangers the president or compromises national security.
The dispute between the administration and the preservation group turned sharply personal months before Friday's Supreme Court filing. Back in April, following a shooting at the White House Correspondents' Association dinner, DOJ Civil Division Assistant Attorney General Brett Shumate sent a letter to the National Trust's attorney, Gregory Craig, urging the group to drop the case.
Shumate wrote bluntly:
"Your client should voluntarily dismiss this frivolous lawsuit today in light of last night's assassination attempt on President Trump. I hope yesterday's narrow miss will help you finally realize the folly of a lawsuit that literally serves no purpose except to stop President Trump no matter the cost. Enough is enough."
Craig refused. In a written response, the National Trust's attorney pushed back on the DOJ's framing.
"Your assertion that this lawsuit put the President's life at 'grave risk' is incorrect and irresponsible. Simply put, this case does not jeopardize the President's safety in any way."
The exchange reveals how far the administration was willing to go to pressure the group into backing down, and how firmly the National Trust held its ground. The Trump administration has faced similar resistance in other legal arenas; the president recently turned to century-old trade statutes to preserve tariff authority after a separate Supreme Court setback.
The National Trust released its own statement Friday responding to the emergency Supreme Court petition. The group described the administration's legal maneuvering as "transparent efforts to evade the rule of law, frustrate judicial review, and limit the availability of meaningful relief in the courts."
The statement laid out the group's core argument in plain terms:
"Each court reviewing this case has ruled that construction of the Ballroom is unlawful. Each court has seriously and carefully considered the Administration's asserted national security concerns. And each court has ruled that while underground bunker construction can continue, Ballroom construction must stop."
That distinction, bunker construction allowed, ballroom construction halted, undercuts the administration's framing that the lawsuit threatens presidential safety. The courts have drawn a clear line between the security infrastructure underground and the social venue above it. If the bunker can be built without the ballroom, the national-security argument for the ballroom itself rests on weaker ground.
The Washington Examiner reached out to the National Trust for comment on Trump's "treasonists" post specifically. The group's response to that request was not reported as of publication.
The ballroom fight fits a broader pattern in which the Trump administration has pushed forward on executive priorities only to run into legal obstacles that demand legislative buy-in. The appeals court ruling requiring congressional approval before construction can proceed puts the project's future squarely in the hands of lawmakers, and no congressional action on the matter has been reported.
That dynamic is not unique to this case. Other Trump administration figures have faced their own institutional resistance, including impeachment articles filed against Education Secretary Linda McMahon by a House Democrat earlier this year.
Meanwhile, the accusation of "treason", or "treasonists," as Trump coined it, carries serious weight even when used loosely. Treason is a constitutionally defined crime, the most grave offense in American law. Applying that label to a nonprofit that filed a civil lawsuit and won in two federal courts stretches the word well past its legal meaning. The National Trust exercised its right to sue the government and prevailed. That is not treason. It is the legal system working exactly as designed.
The question of accountability runs both directions. If the administration believed the National Trust was genuinely compromising classified information through the litigation, the proper response would be a criminal referral or a classified-information protective order, not a social-media post. No such action has been reported. Accountability for government officials who face allegations of misconduct has been a recurring theme in Washington, and the standard should apply evenly.
The emergency petition now sits with the Supreme Court. If the justices grant the administration's request, ballroom construction could resume while the broader legal challenge continues. If they decline, the project stays frozen until Congress acts, or until the administration finds another legal path forward.
Several questions remain unanswered. What specific regulatory steps does the National Trust allege the administration skipped? Has any member of Congress introduced legislation to authorize the construction, as the appeals court's ruling would require? And what, precisely, does Trump mean when he says the group "revealed Top Military Secrets", through what mechanism, and with what evidence?
None of those questions have public answers yet. What is clear is that two federal courts examined the administration's national-security arguments, took them seriously, and still ruled the ballroom construction unlawful. The courts did not dismiss the security concerns, they separated the bunker from the ballroom and treated each on its merits.
Calling your legal opponents traitors after they beat you in court twice is not a national-security strategy. It is a tell that the legal arguments are running thin.
