The U.S. National Park Service (NPS) has found that a proposed Triumphal Arch, part of a plan by President Donald Trump, would adversely affect dozens of historic sites in and around Washington, D.C.

Following the reopening of the public comment period for the project's assessment, the NPS listed nearly 40 locations across Washington, D.C. that could be impacted.

The assessment indicates that the proposed 250-foot tall structure would alter views across Washington, D.C. and Arlington Cemetery.
