President Trump's plans to overhaul the Kennedy Center, build a golf course on East Potomac Park, and construct a triumphal arch near Arlington National Cemetery face legal challenges from preservation groups. A coalition including the National Trust for Historic Preservation and the American Institute of Architects filed a lawsuit Monday demanding environmental reviews and congressional approval for the Kennedy Center project. They argue Trump’s changes violate federal historic preservation laws and exceed executive authority over federal lands. The White House ballroom project, replacing the demolished East Wing with a Trump-branded space, is also under scrutiny.

Judge Richard J. Leon has delayed rulings, citing inconsistent government arguments about the project’s legal basis.
