Trump motorcade – A video posted by Steven Cheung shows President Donald Trump’s motorcade driving across the drained Lincoln Memorial Reflecting Pool during an inspection of the renovation in early May, as the pool’s blue polyurea coating later began peeling and algae turned t
The Lincoln Memorial Reflecting Pool was drained, repainted “American flag blue” ahead of the nation’s 250th anniversary, and open for a highly staged look at the renovation work. Then President Donald Trump’s motorcade drove across the basin.
The footage. posted on X by White House Communications Director Steven Cheung on May 7. quickly became a spark for a new blame battle when the pool’s condition worsened weeks later—when portions of the newly applied blue polyurea coating started to peel. algae turned the water murky green. and reports emerged of a long gash in the liner.
Cheung shared the video again as it resurfaced on Wednesday. June 24. when Anderson Cooper asked Scientific American reporter Adam Kovac whether the vehicles could have contributed to the damage. Cooper referenced online speculation about whether the presidential motorcade driving in early May—along with other equipment—may have caused or contributed to the problem with the blue coating.
Experts urge caution before anyone decides who caused what. Aquatic Council chair Tim Auerhahn said there is not enough definitive information to conclude that vehicle traffic. including the presidential motorcade or construction equipment. caused the apparent delamination of the coating. In a statement to Newsweek. Auerhahn said investigators should weigh multiple factors. including surface preparation. coating application and cure time. the weight and distribution of loads. the location of vehicle travel relative to the observed failures. and the condition of the underlying substrate. He added that the apparent damage may prove to be the result of multiple contributing factors rather than a single point of failure.
Croc Coatings president Jim Hobart said polyurea is generally durable and designed to withstand regular vehicle traffic when properly installed. He also pointed to timing: polyurea coatings typically require at least 24 hours to cure before vehicles drive over them. and his company recommends 36 to 48 hours for heavier vehicles. It remains unclear how long the Reflecting Pool coating had cured before the motorcade crossed it.
While the question of causation stays contested. the government account of the damage has already put sharp focus on what was allegedly found on-site. On Wednesday, June 24, National Park Service Deputy Director for Operations Frank Lands filed a declaration describing an official response. The declaration says that on June 9, 2026—after the rehabilitation project was substantially complete—the U.S. Park Police responded to an NPS report of damage to the Reflecting Pool. including a caulk over the foam sealant that was cut with a sharp knife or razor and destruction of delaminating surface material. Lands also wrote that approximately 70 fence post tops were thrown into the pool.
Against that backdrop, the Trump administration has promoted a vandalism narrative rather than a construction-related one. President Donald Trump has repeatedly blamed the damage on acts of vandalism by “deranged leftists. ” alleging without presenting evidence that someone used a sharp object to slice the liner and introduce chemicals that fueled algae growth.
On Tuesday. June 23. Trump announced that six people had been arrested in connection with alleged vandalism. claiming a “350-foot gash” was created with “a very sharp knife or razors.” Trump wrote on Truth Social that it was “purposefully and criminally done. ” adding that repairs would require draining part of the pool around the Fourth of July. White House Press Secretary Karoline Leavitt later defended that position. saying officials had documented “17 police reports” and “six arrests” connected to vandalism at the site.
One of the people arrested is 67-year-old former Olympian David Hearn. He insists he committed no crime and says he plans to fight the allegation in court. “I did nothing wrong,” Hearn told Newsweek on Tuesday. He also told The Washington Post that he picked up a piece of paint that was already flaking off and did not remove any material from the pool. adding. “I didn’t vandalize anything. … I didn’t destroy or break or peel anything. By the time I realized what was going on, I was being put in handcuffs,” according to his account.
The dispute now boils down to an uncomfortable timing question and an equally sharp clash of explanations: whether the damage points back to vehicle traffic and renovation factors—or whether it fits the sharp-object-and-chemicals vandalism story the White House has pushed. For now. industry experts say the evidence isn’t definitive enough to make the blame stick to any single cause. even as officials describe physical damage they say was linked to deliberate intrusion.
