A federal judge has expressed skepticism over President Donald Trump's $400 million White House ballroom project, amid renewed efforts by preservationists to halt construction. The East Wing demolition began in October to make way for a 90,000-square-foot ballroom intended for state dinners, galas, and official events. The National Trust for Historic Preservation has sued the White House for not following federal law, including obtaining approval from Congress, conducting independent reviews, and allowing public comment. The Justice Department defended the project, citing its dual source of funding and authority. Last month, a judge approved the project despite objections from preservationists.
