Trump Administration Challenges Ruling on White House Ballroom Project

A federal appeals court ruled on April 11, 2026, that construction of a proposed ballroom at the White House can temporarily proceed while the Trump administration challenges a lower court order. The U.S. Court of Appeals for the District of Columbia Circuit issued a 2-1 decision allowing work to continue until April 17, 2026.

The ruling stays a previous order from U.S. District Judge Richard Leon, who had ruled on March 31, 2026, that construction must stop by April 14, 2026, unless Congress authorizes the project. Judge Leon had previously found that no existing law provides the president with the legal authority to build such a structure at the White House without congressional approval.

Legal Dispute and Project Scope

The legal battle began in December when the National Trust for Historic Preservation filed a lawsuit to block the project. The proposed ballroom is a 90,000-square-foot neoclassical structure intended to seat 1,000 guests. The project is located on the site of the White House East Wing, which the administration began demolishing in October to make room for the new construction.

Cost estimates for the project vary between $300 million and $400 million. Architect Shalom Baranes presented elevation drawings of the ballroom to the National Capital Planning Commission on January 8, 2026.

The appeals court decision allows the administration time to seek a ruling from the Supreme Court regarding the future of the site. The three-judge panel sent the case back to the lower court with instructions to clarify specific issues regarding the necessity of the project.

Safety and National Security Claims

The Trump administration has argued that the construction is a matter of national security. Lawyers for the president stated in court filings that the ballroom and associated measures are vital project for the safety and security of the White House and the President, his family, and his staff.

On March 29, 2026, President Trump told reporters that the project includes upgrades to a secure bunker from the Franklin D. Roosevelt era. He stated that the military is building a big complex under the ballroom.

The appeals court noted that it could not fairly determine, on this hurried record how these safety and security concerns might affect the ultimate outcome of the case. The court granted the temporary extension through April 17, 2026, to allow for further review.

President Trump has defended the project by stating the large space is necessary for hosting significant events. The administration continues to maintain that Congress has no role in the construction of the facility.
