• The ruling stems from a lawsuit by the National Trust for Historic Preservation.

A federal judge, U.S. District Judge Richard Leon, has ordered the Trump administration to stop construction of a $400 million ballroom at the White House, set to replace the demolished East Wing, pending congressional approval. Leon granted a preliminary injunction in response to a lawsuit from the National Trust for Historic Preservation, which argued that President Trump exceeded his authority by proceeding without legislative consent, stating that “no statute comes close to giving the President the authority he claims to have,” according to Reuters and CBS News.

During the ruling, Judge Leon emphasized that the President is the steward of the White House for future generations, not its owner, and directed that any construction necessary for safety and security purposes could continue. This pause on the ballroom project is temporary, allowing for a potential appeal from the Trump administration as they prepare to contest the injunction, according to Los Angeles Times and NPR.

The National Trust for Historic Preservation initiated the lawsuit in December, citing concerns over the lack of adherence to federal guidelines following the demolition of the East Wing, originally built in 1902. Leon's ruling indicates a strong inclination towards the preservationist claims, suggesting they are likely to prevail in court, as he remarked, "Unfortunately for defendants, unless and until Congress blesses this project through statutory authorization, construction has to stop," according to South China Morning Post and Los Angeles Times.

Trump criticized the ruling in a social media post, contending that the project is being financed entirely through private donations, which he claims are not costing taxpayers. He voiced his frustration with the preservation group's actions and implied a misalignment with their appreciation for efforts to enhance Washington's architecture, as reported by NPR and CBS News.
