The National Trust for Historic Preservation filed a lawsuit against President Donald Trump and federal agencies on Dec. 12 over the ballroom construction project at the White House.
Construction on the project, which involves demolishing part of the executive mansion and building a 90,000-square-foot ballroom, began in September. The project is expected to cost about $300 million, all of which is expected to be funded by private donors, including Trump. The Trump administration released a list of the private donors in October.
