Workers around Washington’s Lincoln Memorial Reflecting Pool are putting up fencing and preparing to drain the pool again after algae growth and peeling coating appeared weeks after a costly recent renovation. Multiple outlets report that the renovation, ordered by President Donald Trump, included repainting the pool—described as turning it “American flag blue”—and that the new coating began to peel while the water turned green with algae shortly after the work was completed. Trump says the problems are linked to vandalism and has claimed, without providing evidence, that several people have been arrested and others are under investigation in connection with the damage. NBC News and other reports describe Trump’s allegations about proof in court, while Reuters and other coverage point to the extent of the algae and the visual condition of the paint. Separate reporting also notes Trump’s comments that the pool may not be repaired in time for the Fourth of July, as the administration weighs further work. The National Park Service, as reported by AFP, says law enforcement took action involving five arrested for vandalism and five additional federal citations.
