The opinion said that “at this preliminary stage, the National Trust has shown, compellingly, that Congress has not ceded unfettered authority to the Executive Branch to dramatically redesign, reshape, and reconstruct the White House — the People’s House — to fit a particular President’s desires.” “From the beginning, our position has been clear and consistent: the law states that only Congress can authorize the construction of a ballroom at the White House.” The appellate court said it would stay its own ruling to allow the administration to appeal to the Supreme Court. The Trump administration has argued that the president has sweeping authority to approve changes to the White House grounds. The case is National Trust for Historic Preservation v. National Park Service.
