Federal Judge Halts Construction of Donald Trump's $400 Million White House Ballroom

A federal judge on March 31, 2026, halted construction of President Donald Trump's planned $400 million ballroom at the White House, ruling that the project cannot proceed without explicit approval from Congress. U.S. District Judge Richard Leon granted a preliminary injunction requested by the National Trust for Historic Preservation, a nonprofit that sued the Trump administration in December 2025 after the administration demolished the historic East Wing to make way for the project. Leon, a senior judge appointed by Republican President George W. Bush, wrote in his 35-page ruling that no law comes close to granting the president the authority he claims over the White House grounds. The injunction keeps the 90,000-square-foot project on hold while the underlying lawsuit proceeds. The ruling marks a significant legal setback for one of Trump's most publicly championed initiatives.

Judge: president is custodian, not owner In the ruling, Leon drew a sharp distinction between the president's role and his rights over the White House as a property. „The President of the United States is the custodian of the White House for future generations of First Families. He is not, however, the owner!” — Richard Leon via Reuters Leon also concluded that the National Trust will most likely prevail when the case is considered on its merits. The judge left a clear path forward, noting it is not too late for the administration to seek congressional authorization. „The president may at any time request that Congress expressly authorize him to build a ballroom and to do so with private funds” — Richard Leon via RTVE.es The ruling came after a March 17 hearing at which Leon pressed Justice Department lawyers on their shifting explanations for the president's authority, calling the White House grounds a "special place" and an "iconic symbol" of the nation. The injunction is set to take effect in 14 days to allow for the appeals process.

The East Wing of the White House was originally constructed in 1902 and later expanded during Franklin D. Roosevelt's presidency. The Trump administration demolished the structure to make way for the ballroom project, which the president has described as the "finest" ballroom in the country. The National Trust for Historic Preservation was founded in 1949 by congressional charter specifically to support the preservation of historically significant American sites and structures. The lawsuit, filed in December 2025, argued that neither the president nor the National Park Service, which manages the White House grounds, had the authority to raze the historic structure or erect a major new facility without explicit congressional approval.

Trump calls ruling wrong, vows appeal and attacks plaintiff Trump rejected the ruling within minutes of its issuance, posting a lengthy response on his Truth Social platform. He described the National Trust for Historic Preservation as a group of "left-wing extremists" and dismissed the court's decision as "so wrong," announcing plans to appeal. Trump defended the project by pointing out that it is funded entirely by private donors at no cost to taxpayers, is on schedule, and within budget. The administration had argued before the court that the ballroom would modernize White House infrastructure, bolster security, and ease strain on the Executive Mansion, which frequently relies on temporary outdoor structures for large events. Officials also cited the need to host foreign dignitaries, including King Charles III, as justification for the project. Trump also used the post to renew criticism of Federal Reserve Chair Jerome Powell, comparing the ballroom project unfavorably to what he described as damage done to the Fed's building. 999 (people) — planned capacity of the White House ballroom

Approval process incomplete as legal battle begins The project had cleared one of two required federal design reviews before the injunction was issued. A panel of the U.S. Commission of Fine Arts, composed entirely of Trump appointees, voted 6-0 on February 19, 2026, to approve the design. The National Capital Planning Commission, a second review body, was scheduled to vote on the project on April 2, 2026. Leon's ruling, however, means that favorable votes from both commissions may not be sufficient for the project to advance. The ballroom is part of Trump's broader effort to reshape Washington's monumental core, which also includes plans for a 250-foot arch and changes at the Kennedy Center. The Justice Department, which opposed the injunction and defended the ballroom as an allowable alteration to the White House grounds, now faces the task of mounting an appeal within the 14-day window before the injunction takes full effect.
