The Trust contends that the construction, which has already involved the demolition of the East Wing, violates federal law and circumvents required procedures. Legal Claims and Arguments The lawsuit alleges that Trump accelerated the project in violation of the Administrative Procedures Act and the National Environmental Policy Act, while also exceeding his constitutional authority by not consulting lawmakers. “No president is legally allowed to tear down parts of the White House without any review whatsoever — not President Trump, not President Biden, and not anyone else,” the complaint states. The Trust argues that no further work should proceed until design reviews, environmental assessments, public comment and congressional deliberation are completed. Federal Oversight Requirements The lawsuit stresses that White House projects of this scale must involve the National Capital Planning Commission, the Commission on Fine Arts and Congress before any demolition or construction. The Trust previously wrote to these bodies on October 21, after the East Wing demolition began, urging the administration to halt the project and comply with federal law. Trump’s position and private financing Trump has stated that the ballroom is privately financed, including with his own money, citing practical concerns such as accommodating large events and avoiding outdoor tents in inclement weather. However, the Trust notes that using private funds does not exempt the project from federal oversight. Review process timeline Will Scharf, chairman of the National Capital Planning Commission and a Trump aide, said plans for the new ballroom will be presented to the commission in December. He added that the review would take place at a “normal and deliberative pace”, but the Trust argued that submitting plans after construction had started was insufficient and legally improper. Significance of the project The complaint emphasizes the historic and public importance of the White House, noting that public involvement in the review process is crucial for a structure “perhaps the most recognizable and historically significant building in the country.” Defendants Named in Lawsuit In addition to President Trump, the lawsuit names the National Park Service, the Department of the Interior, the General Services Administration and agency leaders as defendants.
