Trump claims vandals slashed Reflecting Pool surface he boasted was knife-proof

Donald Trump boasted about the durability of the newly renovated Lincoln Memorial Reflecting Pool weeks before announcing the site would need to be drained again.

Speaking on 4 May 2026, the US president said the pool’s surface is “very, very strong”, claiming that even a knife couldn’t cut through it.

The structure has undergone weeks of renovation after Trump decided to drain the pool and have its surface spray-painted with what he called an “American flag-blue” coating similar to those used in chlorinated swimming pools.

“This will last for at least 50 years, and you'll never have a leak,” he added

On Tuesday (23 June), Mr Trump announced that the pool will need to be drained again due to alleged vandalism.

“We have a 290,300-foot slit right through it.”
