Trump sued by preservation group over $300m White House ballroom project

National Trust looks to halt construction, claiming Trump tore down historic East Wing without needed permission

Donald Trump is facing a federal lawsuit seeking to halt construction on his $300m White House ballroom, with historic preservationists accusing the president of violating multiple federal laws by tearing down part of the iconic building without required reviews or congressional approval.

The legal challenge, filed on Friday by the National Trust for Historic Preservation in the US district court for the District of Columbia, represents the most significant attempt yet to stop Trump's 90,000-sq-ft addition to the White House complex. The organization is seeking a temporary restraining order to freeze all construction activities until proper federal oversight procedures are completed.
