Pressed by CBS News’ @Ed O’Keefe on whether there is evidence vandals damaged the Lincoln Memorial Reflecting Pool, President Trump pointed to what he described as long cuts in the pool’s surface and claimed someone may have deliberately caused the recent algae outbreak. “I saw it, they cut it. They cut it very violently,” Trump said. “The same thing with the floor, they cut it. And then they lifted it, they pulled it, and that's what it is.” #news #trump #reflectingpool #washingtondc #lincolnme

Former President Biden criticized President Trump and made a comment about the ongoing Reflecting Pool renovations during his speech at the 2026 Fight Back & Win Gala hosted by the Maryland Democratic Party on Saturday. “The Reflecting Pool reflects something even worse than the narcissism and incompetence at the core of this administration,” Biden said. “It’s the corruption… the brazen, blatant corruption. Corruption on a scale never seen before in American history in any administration.” #bide
