Workers racing to turn reflecting pool blue for Trump may be at risk, union warns

Union representative concerned about safety as workers rush to finish repainting DC pool before 250th celebrations

Workers renovating one of Washington DC’s most historically symbolic sites in a project ordered by Donald Trump may be risking their safety as they race to finish on time for the US’s 250th anniversary celebrations, a union monitoring the site has warned.

Trade union scrutiny has focused on the reflecting pool on the US capital’s National Mall – scene of Martin Luther King’s 1963 “I have a dream speech” – after it was drained of water and fenced off from the public to allow contractors the chance to upgrade it by 4 July.
