Trump claims vandals will force drainage of algae-plagued Reflecting Pool

By Kaanita Iyer, Aleena Fayaz, CNN

(CNN) — President Donald Trump claimed Saturday, without providing evidence, that vandals damaged the algae-plagued Reflecting Pool on the National Mall and that the water will need to be drained for repairs.

Trump said police arrested “many additional people” for the vandalism, though one told CNN he was merely touching a piece of partially detached blue material from the recent renovation.

“The Reflecting Pool was never so beautiful as it was just one week ago,” Trump said, adding that it will repaired quickly. Trump’s recent renovation, totaling $14 million, marked the latest in the president’s efforts to beautify Washington, DC, with architectural changes that have included building a White House ballroom and refurbishing run-down fountains.

Now, what was meant to be a straightforward task to return the century-old pool to its intended glory ahead of America’s 250th anniversary has become a spectacle, drawing tourists and locals to the pool for the wrong reason.

Three-time US Olympian David Hearn told CNN that police arrested him Friday after he said he touched a flap of blue material partially detached from the bottom of the pool. Hearn, who says he has a background in material science, told CNN he checked it out following a bike ride after reading reports of algae in the water and paint or sealant peeling off the bottom.

Hearn said he was curious about a partially attached blue flap he saw at the bottom of the Reflecting Pool. Upon reaching into the water, Hearn said he “sort of felt the end” and “bent it around a little bit.”

Hearn said a US National Park Service staffer instructed him not to reach into the water. After Hearn returned to his bike, he said was soon encountered by National Guard members and eventually arrested by the US Park Police. He said he was charged with destruction and defacing government property and disobeying a government employee.

The Olympic canoeist denied vandalizing the Reflecting Pool and said his actions were that of a “curious citizen.”

“There’s nothing about the Reflecting Pool that was in any different condition after I left there than it had before I went by there yesterday. I didn’t remove anything. I didn’t break, tear, peel, or rip, or destroy anything,” Hearn said Saturday.

He is set to appear in court on July 9. CNN has reached out to the US Park Police and the National Park Service to ask about Hearn’s account and for information on any other arrests.

Pet project for the president

Earlier this year, the president described the Lincoln Memorial Reflecting Pool as “absolutely filthy,” vowing to clean up the landmark and make it “look gorgeous, beautiful” so it reflects the federal monuments around it.

But with the Fourth of July and America’s 250th anniversary fast approaching, the pool that sits near the feet of Abraham Lincoln’s statue has instead come to reflect the deep divisions over those beautification efforts — and Trump’s presidency itself.

Trump on Friday first echoed claims that surfaced in right-wing circles that the pool’s broader problems are a result of vandalism, and linked it to the etching of “8647” into the grass on the National Mall days prior, adding that law enforcement is investigating.

“We’ve had some real problems with Vandalism at the beautiful Reflecting Pool,” Trump wrote on Truth Social, without citing evidence. He said the algae was “75% gone” and the “vandalized” area will be fixed early next week.

Tourists and local residents alike have flocked to the site in recent days, shooting video of the murky green water for social media posts that feature either a condemnation of Trump’s presidency or a passionate defense of the effort to clean up DC. Some peeled off strips of the blue material to take as souvenirs. Others filmed federal workers pouring bottles of hydrogen peroxide into the water.

The Interior Department has dismissed the visible signs of algae that have only become more abundant as DC’s warm, muggy weather fosters its growth. In a post on X Wednesday, the department’s press office touted its efforts to clear out the algae and described the water as being “crystal clear.”

CNN has reached out to the Interior Department for comment and additional details on the cleanup efforts.

Trump set out in late March to accomplish the renovation that has eluded previous presidents. In a post on Truth Social, he criticized the Biden administration for not taking on the project after a $34 million reconstruction effort under President Barack Obama proved unsuccessful.

In the weeks that followed, Trump expanded the scope of the project and ordered cosmetic changes, including painting the bottom of the pool “American flag blue.” The paint change immediately sparked a lawsuit from a nonprofit group, which argued the project violated federal laws requiring the Interior Department to complete a consultation process before beginning the work.

The president also wanted the project to be complete before July Fourth, an expedited timeline that the administration acknowledged drove up the cost — nearly seven times as much as the initial estimate of $1.8 million.

Trump made a visit to the site to survey progress, and weeks before it was complete, he began celebrating by posting an AI-generated image to Truth Social of him and some of his Cabinet members smiling while floating in the pool.

‘Residual algae’ woes

But just a day after the reservoir was filled with water, algae was already visible from the water’s edge.

The Interior Department told CNN at the time that the algae was “residual” and a normal part of the early process of restarting water flow.

However, within days, clumps of algae took over the pool, prompting the administration to send in workers to vacuum it out, install a filtration known as the “ozone nanobubbler” and dump in gallons of hydrogen peroxide.

To make matters worse for the Trump administration, earlier this week, blue material at the bottom of pool began peeling off. It is unclear whether the material is paint or sealant or what caused it to come up.

Democrats online were quick to gloat.

“You can’t make this up: after railing about waste, fraud, and abuse, the Trump Administration spent $14 million on a reflecting pool reno that’s now peeling and chock full of algae,” Democratic Sen. Jeff Merkley of Oregon said in a post on X. “I’m pressing to get answers for this embarrassing waste of resources.”

Beyond lawmakers, the pool saga has prompted an online debate, filled with false claims and conspiracy theories.

Left-leaning social media users latched onto a clip of a Fox News personality defending the renovation, incorrectly claiming that he was describing the visibly green water as blue. (He was referring to the pool’s bottom.)

Meanwhile, conservative media personality Grant Stinchfield alleged the excessive algae is a product of liberal “sabotage.”

“Is it nefarious? I tend to think so,” Stinchfield told his online viewers from outside the Reflecting Pool.

A video posted by conservative influencer Nick Sortor on Thursday night has also garnered attention. The video appeared to show “8647” traced into the algae at the bottom of the pool. CNN could not independently see that tracing on Saturday. When used as slang, the number 86 can refer to getting rid of or tossing something out. Trump is the 47th president. The phrase has recently been used to signal opposition to Trump.

Outside the pool, a collection of curiosity seekers and social media influencers have also gathered. One woman showed up with a banner painted with a green “Algae” as she chanted, “Algae’s smarter than MAGA.”

Matthew Weimer of California, who was in Washington, DC, to visit friends, applauded the renovation.

“I think it’s pretty great that somebody cared enough to do something about it,” Weimer said. When asked about criticisms over the pool, he said: “The people who are criticizing, what are they doing to make things better?”

Qayla Sykes, who visited from Connecticut for a bachelorette party, made a quick stop at the National Mall to take in the spectacle.

“It looks pretty gross. I’ve taken about like 20 pictures already, especially of the people cleaning it, because I don’t know if I’ll ever see this again in my lifetime,” she said. “Hopefully not.”
