President Donald Trump expressed confidence this week that renovation work on the Lincoln Memorial’s iconic Reflecting Pool is near completion, after multiple setbacks dragged out the restoration.

The multimillion-dollar resurfacing and painting project to give the Reflecting Pool a facelift ahead of the U.S.’s 250th birthday began in April. The effort quickly became beleaguered by an algae bloom, and the pool’s new blue paint appeared to be peeling off, leading to allegations of extensive vandalism and another round of renovations.
