@congresswatchdaily: Donald Trump’s $14.2m attempt to turn the Lincoln Memorial reflecting pool from what the US president described as a “filthy” and “dirty” site into a “beautiful” monument has encountered a hitch. The water is green again. Days after the renovation was finished, algae have frustrated Trump’s attempt to transform the shade of the pool to “American flag blue” in time for the country’s 250th birthday. The reflecting pool – one of Washington DC’s most historically symbolic attractions, and the scene of Martin Luther King’s 1963 “I have a dream” speech – has been one element of Trump’s efforts to recondition the country’s capital during his second presidency.
