Donald Trump claimed that federal authorities made multiple arrests related to vandalism at the Lincoln Memorial Reflecting Pool, alleging that vandals poured corrosive chemicals into the pool, caused a large gash in its lining, damaged the surrounding grass, and left the water with algae and peeling paint. He also stated the pool must be drained for repairs and, according to one report, suggested lining it with 'American flag blue' to improve its reflection of the Washington Monument. Trump did not provide evidence to support any of these claims. A user on Bluesky accused Trump of being the primary vandal in Washington, D.C., and of violating constitutional principles and harming citizens.
