The administration of U.S. President Donald Trump has filed an emergency motion to resume construction of a White House ballroom after a court ordered the project halted.

Officials argue that the pause leaves a large excavation site near the White House, posing potential national security risks, and say the project includes features like blast-resistant materials and drone protection.

The administration called the court’s decision improper and insists the work is urgent and already partially completed.

The dispute follows a ruling by Judge Richard Leon requiring congressional approval for the project, which critics say could significantly alter historic parts of the White House, Al-Jazeera has reported.

Preservation groups have opposed the project, especially after the demolition of the East Wing sparked public backlash and legal challenges.
