WASHINGTON (Diya TV) — A federal judge has ordered the administration of Donald Trump to halt construction of a $400 million ballroom at the White House, unless Congress approves the plan. The ruling marks a major legal setback for a project that has sparked debate over presidential authority and historic preservation.

U.S. District Judge Richard Leon issued a preliminary injunction to stop the project. He ruled that the administration likely lacks the legal authority to move forward without approval from Congress.

Leon wrote that the president serves as a steward of the White House, not its owner. He said no law appears to support the authority claimed for the construction project. The ruling came in response to a lawsuit filed by the National Trust for Historic Preservation. The group argued that the project could harm a historic landmark and should undergo an independent review before any work continues.

Leon paused the enforcement of his order for 14 days. He said the delay allows time to address “novel and weighty issues” raised in the case. He also noted that stopping construction immediately could create logistical challenges. The judge acknowledged that the administration may appeal the decision. He added that any work needed for the safety and security of the White House can continue during the pause.

At the center of the dispute is whether a president can approve major structural changes to the White House without Congress. The preservation group says such authority does not exist. The lawsuit asked the court to stop construction until officials complete independent reviews and secure congressional approval. The group argued that the project risks altering the historic character of the White House complex. The Justice Department said the administration plans to appeal. Officials have criticized the lawsuit and defended the project as lawful.

Trump has strongly defended the ballroom project. He said the construction remains under budget and ahead of schedule. He also stressed that private donors, not taxpayers, are funding the project. Trump said the ballroom will not interfere with the existing structure. He described it as a long-standing idea that dates back more than a century. Construction began on Oct. 20 last year. Crews started by demolishing part of the East Wing. The administration said the new ballroom will stand separately from the main building.

The White House said the project includes plans to modernize the East Wing. Officials said the ballroom will provide space for large events, including state dinners and official gatherings. Supporters argue that the new space will improve the White House’s ability to host major events. They say it will reduce the need for temporary tents and external venues. Critics, however, warn that the project could set a precedent for future changes without oversight. They stress the importance of preserving the historic integrity of the building.

The case could shape how future administrations approach changes to historic government properties. Legal experts say the ruling raises important questions about checks and balances. The outcome may also influence how courts interpret presidential powers in managing federal landmarks.
