President Trump and the Interior Department marked a clear win at the Lincoln Reflecting Pool after an algae problem that had plagued reopenings was eliminated, with new photos, a technology credit from officials, and an investigation into vandalism. The administration highlighted advanced nanobubbler equipment and National Park Service cleanup work, shared before-and-after images, and placed responsibility for damage squarely on a small group of vandals. Officials say vacuuming is finishing the job and repairs for gashes will be handled as needed, while law enforcement seeks tips on suspects. The tone from the administration is straightforward: technology solved the algae issue and vandals will be held accountable.
President Trump posted photos showing a crystal-clear pool reflecting the Washington Monument, and he shared a public safety notice tied to the damage. “The U.S. Park Police is seeking the public’s assistance in identifying the individual in the notice below in connection with a Destruction of Government Property investigation related to the Reflecting Pool,” Trump wrote Sunday on Truth Social. The images were paired with Interior Department messaging crediting the cleanup effort.
The Interior memo credited an industrial partner and a specific technology for the turnaround at the pool. “The advanced nanobubbler technology very effectively killed the algae that has plagued every Lincoln Reflecting Pool reopening — most infamously Obama’s reopening — since 1922,” Dei Gratia Minerals founder Greg Wischer, Interior’s deputy assistant secretary for land and minerals management, wrote in a letter shared with Interior Secretary Doug Burgum and Trump. That direct claim framed the restoration as both scientific and decisive.
Officials described the final cleanup steps underway as crews remove dead algae from the pool floor. “The Reflecting Pool water is crystal clear, and our National Park Service team is now vacuuming up the dead algae resting on the bottom of some parts of the Reflecting Pool — just like the destroyed Iranian Navy resting on the bottom of the Persian Gulf.” The memo used vivid language to underline how complete the kill-off of algae proved to be.
Photographs accompanying the announcements show the pool stretching toward the Washington Monument under clear skies, with reflections sharp and water visibly blue. Trump also shared an Interior press post quoting the Wischer memo and celebrating the technological fix. Officials emphasized the visual impact as much as the technical win, making the point that a clean reflecting pool is both symbolic and functional.
“The vacuuming is the final maintenance step after refilling the pool, and it will be complete in a few days,” his memo continued. “Already, the section of the Reflecting Pool closest to the Lincoln Memorial has been vacuumed up, and the beautiful American Flag Blue coating on the bottom of the pool can be seen clearly.” That timeline gave the public a near-term view of when the site would be fully ready for visitors.
The memo contrasted the current approach with prior problems during reopenings, laying blame at past administrations for recurring algae troubles. “Previous administrations — most notably under Obama — failed to maintain the Reflecting Pool, and after refilling the pool, the water would quickly become murky and thick with massive clumps of algae floating on the surface,” the memo concluded. The administration used that contrast to highlight the new technology and maintenance plan.
“The photos below show how the nanobubbler technology and vacuuming have been incredibly effective, making the water crystal clear with the American Flag Blue coating shining brightly on the bottom of the pool. As our National Park Service team noted, the Reflecting Pool is now so ‘blue’ that the Fake News Media, which has been staked out at the Reflecting Pool for weeks, has fled!” The messaging paired technical detail with a blunt political jab about media reaction.
Interior Secretary Doug Burgum described the restoration as a success while addressing vandalism that increased costs and added repairs. “The Reflecting Pool has been a big success,” he said. “And we’ve got 340 million people in this country that are celebrating 250. We did have a few vandals, but all that’s going to be repairable, and that’ll all be fixed in the coming weeks as we go forward.” His remarks framed vandalism as an obstacle the administration will repair quickly.
Burgum also weighed in on the damage assessment and repair options, suggesting a partial drain might be sufficient to finish repairs. “We don’t know if we need to drain the whole thing or not because, you know, the cutting happened on the edge, and, of course, it slopes from the edge,” according to Burgum. “We may be able to partially drain it and do the repair. To be able to fix it, we may not have to drain the whole thing, but it could go very quickly.”
On accountability, Burgum emphasized surprise and ongoing security measures around the memorial after the incident. “We weren’t expecting that we were going to have a small group of people that wanted to try to destroy effectively what is part of the Lincoln Memorial,” Burgum told ABC. “There’s plenty of cameras around the Lincoln statue and around the memorial, but the Reflecting Pool had gone for, you know, decades without vandalism.” The administration is pursuing identification and repair while touting the successful cleanup.
