Algae cleanup continues at the Lincoln Memorial Reflecting Pool, in Washington, DC, on June 23, 2026. US President Donald Trump on Monday threatened jail time for anyone seeking to damage one of his signature renovation projects, the Reflecting Pool at the Lincoln Memorial in Washington, whose overhaul has become a political flashpoint. Trump brought in contractors to drain the 610-meter pool and repaint it "American flag blue." But soon after completion of the work the coating has begun to peel off and algae turned the pool's water a mucky green -- setbacks the president blamed on vandals, without providing evidence.
