A video posted by journalist Amanda Moore captures National Guard personnel patrolling the reflecting pool on the National Mall and a promotional event called the Trump Great America State Fair, taking place near the Lincoln Memorial during the nation’s 250th birthday celebrations. The National Mall, a historic site in Washington, D.C., has been the focus of increased security presence in recent weeks. Moore, who has spent the past 18 months documenting the administration’s actions, posted the eight‑second clip that quickly gained widespread attention. The audio in the video warned, “Loitering is not permitted in this area,” and instructed viewers to “Please proceed to a designated location.” Uniformed National Guard members were seen walking along the pool’s edge, which has been described as algae‑covered. The event featured a model of a triumphal arch that the president has said he intends to build across the Potomac River. Moore reported finding few visitors, limited supplies of napkins, and a weathered arch model. She said the footage has attracted attention. The State Fair continues as part of the 250th birthday observances, and the planned arch remains a subject of discussion.
