The U.S. security apparatus is keeping watch ​at the Lincoln Memorial Reflecting Pool, whose blue color has been fouled by green algae after being newly renovated at President Donald Trump’s request.

National Guard troops ‌patrol the area around the roughly 2,000-foot-long (610-meter) basin on Washington’s National Mall in groups of threes and fours. Solar-powered ​light towers illuminate the area at night and roughly a half-dozen mobile security stations outfitted with surveillance cameras ring ⁠the perimeter.

The stepped-up security measures follow a $14.7 million refurbishment of the Reflecting Pool. Mr. Trump has blamed dark-of-night saboteurs for the issues with the project. While no evidence has emerged to support Mr. Trump’s claim that a vandal cut a 350-foot (107-meter) gash in the pool, a National Park Service official said in a sworn court statement late ‌on Wednesday (June 24, 2026) that on June 9, U.S. Park Police examined apparent intentional damage to the pool.

The damage included “a caulk over the foam sealant that was cut with a sharp knife or razor and destruction of delaminating surface material,” Frank Lands wrote ‌in the statement, which was submitted as part of the Mr. Trump administration’s response to a lawsuit challenging the renovation of the pool. ‌About ⁠70 fence post tops were also thrown into the pool, according to Lands.

The increased security presence unnerved Mary Jane ⁠Willard, a tourist from Seattle, Washington.

“It’s very sad to come here and see all the fences, to see all the National Guard here, to see all the cameras,” Mr. Willard said on Wednesday (June 24, 2026). “It just shouldn’t be here.”

Three weeks ago, the Trump administration declared victory in completing work to repaint the landmark pool, which stretches from the Lincoln Memorial nearly ​to the Washington Monument. The color was “American flag blue” for ‌the 250th anniversary of U.S. independence on July 4.

In the days since, the pool has been beset by problems, including blooms of algae, a long-running scourge that has tinted the water a vibrant green, and chips of blue liner peeling off the bottom.

Days before the National Mall will host U.S. 250th anniversary celebrations, the Reflecting Pool has become the latest symbol of Mr. Trump’s Washington: a test of his ‌attempts to bend reality in his favor and command law enforcement to his personal whims.

Few details on vandalism arrests

Mr. Trump has shown ​a personal interest in the Reflecting Pool project, one of a series of ways he has sought to put his stamp on Washington’s monumental core.

Pressed on the lack of evidence to support his allegations of vandalism, Mr. Trump told ⁠reporters on Monday (June 22, 2026), “at the right time, you’ll see it. You’ll see it in court.”

The Department of the Interior said in a social media post on Tuesday (June 23, 2026) that six people have been arrested for alleged vandalism at the Reflecting Pool and seven more were issued federal citations. The department said ‌it is also investigating the “gash” that Mr. Trump spoke about, but it has not provided any photos or other evidence to support those claims.

Neither the Department of the Interior nor the U.S. Park Police has disclosed the names of those charged or the offenses they are facing. Neither agency responded to a request for comment on Wednesday (June 24, 2026).

Local and federal court records show no cases in recent days involving vandalism at the Reflecting Pool. Those arrested may not show up in local Washington, D.C. court records unless the U.S. Attorney’s Office decides to bring a case. U.S. Attorney Jeanine Pirro, a Mr. Trump ally, told Fox News in an interview broadcast on Sunday (June 21, 2026) that those charged “will face the criminal justice system.”

Former Olympian handcuffed

One of ‌those arrested was former U.S. Olympian David Hearn. Video posted on social media by conservative journalist Emily Miller showed Hearn, who was cycling near the pool, being approached by ​National Guard troops and later handcuffed by police.

Mr. Hearn, in an interview with The Washington Post, denied destroying or removing any property but said he reached into the pool and grabbed a partially detached piece of the peeling pool liner.

“Treating ordinary ⁠conduct as criminal diverts attention from the real questions of how this project was managed,” Norm Eisen, a lawyer representing Mr. Hearn who has been involved ⁠in a series of lawsuits against the Trump administration, said in a statement. “Using the criminal justice system to target innocent people as a form of distraction is textbook authoritarian behavior.”

Mr. Hearn is due to appear in local Washington, D.C., court on July 9.

Despite the ‌stepped-up surveillance, the atmosphere near the Reflecting Pool was mostly relaxed on Wednesday (June 24, 2026) as tourists enjoyed a sun-soaked early summer morning in Washington.

“I came down to check it out for myself, but I actually think I was expecting something a little different. It looks pretty ​good to me,” said Joanna Walling, who was visiting from Merritt Island, Florida. “It doesn’t look like anyone’s out here vandalizing today.”
