WASHINGTON — A liner along the bottom of the Lincoln Memorial Reflecting Pool was cut with a sharp knife or razor this month, causing damage to the foam sealant installed as part of a $16 million rehabilitation project, a top official at the National Park Service says.

The U.S. Park Police responded June 9 to a complaint by the park service, said Frank Lands, deputy director of operations for the park service. Lands made the statement in a court document filed late Wednesday as part of a lawsuit filed by a nonprofit organization to halt the Trump administration’s work on the project.

His statement does not say when exactly the damage occurred or whether it was a suspected case of vandalism and does not identify anyone who might have been involved.

The police report indicates damage to the pool, “including a caulk over the foam sealant that was cut with a sharp knife or razor and destruction of delaminating surface material,” Lands said. About 70 fence post tops also were thrown into the pool, he said.

The statements are the first time the Republican administration has offered specifics for when and how the Reflecting Pool may have been damaged after work on the project was substantially completed.

Interior Department thought the reported damage was an ‘isolated incident’

A spokesperson for the Interior Department said Thursday that public notification about the damage was delayed because, “at the time of the June 9 incident, the vandalism was under investigation and believed to be isolated. So as not to encourage deranged individuals, we did not announce what we hoped to be an isolated incident.”

Around the same time, park service staff “discovered another incident where fencing around the pool had been forcibly removed and thrown into the pool,” the spokesperson said in an email.

The department soon noticed that “recurring cases and videos of people ripping at the coating began to circulate. We then knew this was not an isolated incident, but a new trend to attempt to damage the Reflecting Pool,” the email said.

President Donald Trump and other officials have repeatedly blamed, without citing evidence, unidentified vandals for peeling paint as well as a “350-foot gash” in the liner and other problems. Six people have been arrested, Trump said this week, without providing details.

The Interior Department said Thursday there have been seven arrests, seven federal citations and 18 police reports filed. The department did not specify what the charges were or identify anyone cited by police.

Trump pledged to beautify the century-old Reflecting Pool before the nation’s 250th birthday celebrations, draining its water and directing the bottom to be painted a color he called “American flag blue.” But after the site was restored, its water was plagued by an algae bloom for more than a week, and pieces of the new coating have appeared to be peeling off the bottom. The pool has largely cleared in recent days after devices called nanobubblers infused ozone into the water to kill algae and bacteria.

Trump’s administration faces a self-imposed deadline to complete the renovation before July Fourth. Trump also has said the federal government would release images to substantiate his claim.

Trump said Wednesday that “sick people” had used razors and box cutters to slice portions of the lining.

Reflecting Pool was refilled between June 4 and June 9

The Associated Press reviewed videos showing that the Reflecting Pool was refilled between June 4 and June 9, meaning the alleged cut reported to law enforcement on June 9 could have occurred before the basin was fully refilled. Days later, pieces of the new blue liner were observed peeling up from the bottom.

The Park Police posted surveillance footage Wednesday evening and asked for help “identifying the individual depicted here in connection with a Destruction of Government Property investigation.” The grainy, 30-second video appears to show a person kneeling down, reaching into the reflecting pool and removing something from the water. Police said it was taken on Friday afternoon.

In his statement to the court, Lands said the parks agency plans to begin draining the Reflecting Pool following Independence Day celebrations to conduct repairs, including assessing and repairing any damage to the lining.

The park service completed more than two months of renovations at the Reflecting Pool in early June. The 2,000-foot-long basin was drained and a tinted, plastic-like liner was installed to waterproof and protect the concrete pool surface, and the pool was refilled with water, Lands said.

The Cultural Landscape Foundation, an education and advocacy group that sued in May to halt work on the project, asked a federal judge to block further renovations.

“It is also not too late to correct course,” the group wrote in a filing Monday. It urged the administration to “engage with experts and the public, and make an informed decision about what is best based on the consultations mandated by the law, instead of once again rushing ahead with half-baked ideas.”
