Reflecting pool to be drained again as Trump claims five vandalism arrests

President says vandals' to blame for algae blooms and peeling paint as $14m renovation to undergo further repairs

The Lincoln Memorial reflecting pool is set to be drained again after Donald Trump said on Monday - without providing proof - that five people were arrested for vandalism and five more are under investigation in connection to the algae blooms and peeling paint that appeared weeks after his ill-fated $14m renovation attempt.

It's not a lot of damage, but we'll probably have to let the water out and refix it. They went in there with a knife," Trump told reporters, describing what he first said was a 290- to 300ft slit in the paint but then later amended to a 350ft slit. He also said someone had put fertilizer into the water, which caused the algae to grow.
