The Supreme Court has temporarily allowed construction to continue on President Trump’s $400 million White House ballroom project, pausing a lower court order that would have halted development. This action provides the justices time to fully consider the administration's request to continue building while a lawsuit proceeds. The administration argues the project, including an underground complex, is vital for national security, citing threats against the President and the need for secure facilities like bomb shelters and missile shielding. The National Trust for Historic Preservation filed the lawsuit, alleging the administration began construction— tearing down the East Wing and building the 90,000-square-foot ballroom— without proper Congressional approval. A previous ruling by the US Court of Appeals upheld a halt to above-ground construction, but that has now been temporarily suspended. Trump has consistently described the project as an unprecedented security upgrade and a grand addition to the White House.
