Claim: US Park Police arrested two Antifa operatives for dumping algae into the Reflecting Pool
According to a Facebook post shared by America's Last Line of Defense, US Park Police allegedly arrested two Antifa operatives after surveillance cameras reportedly caught them dumping buckets of algae into the Lincoln Memorial Reflecting Pool.
The post presented the claim as breaking news and included alleged comments from a law enforcement official.
The post quoted US Park Police Captain Joseph Barron as saying, "As of now they're not cooperating, but we have them on film. Justice will be served."
It further claimed that Barron believed investigators would eventually determine who funded the alleged operation and whether additional actions were planned.
The post concluded by attributing another statement to Barron: "It's that or ten years in prison. They've caused millions in damage," suggesting the suspects could face severe legal consequences for the alleged incident.
Fact Check: The arrest claim originated from a satire page
Despite a multimillion-dollar renovation project that saw President Donald Trump order workers to paint the base of the National Mall's Reflecting Pool blue, algae could still be seen in the water, turning it green.

For context, the Lincoln Memorial Reflecting Pool has recently faced algae-related issues following a $14.2 million renovation carried out during the Trump administration.
The project aimed to give the pool a pristine "American Flag Blue" appearance, but the water soon turned dark green because of an algae bloom.
According to the Interior Department, residual algae in the supply lines and the pool's shallow, warm-water conditions contributed to the bloom. The Reflecting Pool typically draws water from the Tidal Basin, which frequently contains algae.
To address the problem, maintenance crews have treated the water with 12% hydrogen peroxide and relied on a new $1.7 million ozone nanobubbling filtration system designed to eliminate microalgae.
Experts have also noted that algae blooms are a common issue in outdoor water features and do not pose a significant health risk, although they have disappointed some visitors who expected the renovated pool to maintain its intended appearance.
