President Donald Trump was sued on Friday by preservationists seeking an architecture review and congressional approval over his White House ballroom project. The National Trust for Historic Preservation is asking a federal court to stop Trump’s White House ballroom project until it goes through comprehensive design reviews and public comments and wins approval from Congress. The National Trust argues that Trump, by fast-tracking the project, has committed multiple violations of the Administrative Procedures Act and the National Environmental Policy Act, while also exceeding his constitutional authority by not seeking congressional approval for a project of this scale.
