Demonstrators protest against US President Donald Trump's planned "triumphal arch" at Memorial Circle in Washington, DC on October 1, 2026. Trump has said the massive arch he wants to build on a historic location will double as a base for drones and snipers. The proposed giant structure along the Potomac River near the Arlington National Cemetery is part of Trump's drive to put his personal stamp on the capital. (Photo by SAUL LOEB / AFP via Getty Images)
