In brief
In a 5‑to‑4 ruling, the Supreme Court cleared the way for President Donald Trump to proceed with the $400 million ballroom at the White House, overriding lower‑court bans. Chief Justice John Roberts joined the liberal justices in dissent, arguing that the project was likely unlawful because Congress had not approved it. The National Trust for Historic Preservation contended the president could not unilaterally demolish the East Wing. Trump’s administration insists the construction is needed for security and larger events, stating the ballroom will be largely finished by November 2026 and fully operational by August 2028. The decision follows a broader Trump plan to redevelop Washington’s historic sites, including a new helipad, a renovated Reflecting Pool, and a planned “Arc de Trump.”
Supreme Court clears way for Trump to keep building White House ballroom
The U.S. Supreme Court has ruled that construction of a $400 million ballroom at the White House can proceed, a win for President Donald Trump.
In a 5‑to‑4 decision, the justices approved the Trump administration’s emergency request, overriding lower court rulings that would have stopped the project.
Chief Justice John Roberts joined the liberal justices in dissent, arguing that the construction was likely unlawful because Congress had not approved the project.
The National Trust for Historic Preservation sued, claiming the president could not unilaterally demolish the historic East Wing and erect a new ballroom.
Trump dismantled the East Wing in autumn 2023 to begin construction; the White House says the ballroom will be “substantially” finished by November and fully completed by August 2028.
The court found the preservation group lacked standing to sue, and said the Trump administration would likely succeed in arguing that it would suffer “irreparable harm without a stay.”
Roberts wrote in dissent, warning that the decision was “no victory for the separation of powers.”
Trump, who has long cited the need for a larger events space and the building’s importance for security, posted that the “baseless” lawsuit would not halt construction.
The project sits alongside the helipad on the South Lawn and other proposed changes to Washington’s historic landscape, including the renovation of the Reflecting Pool and a planned “Arc de Trump.”
