Crews at the White House have wrapped the building’s north-facing stone columns in partially transparent tarps that picture columns, as workers begin removing layers of old paint from the surface. The scaffolding went up several days ago for the project, which is the most recent in a series of renovations President Donald Trump has overseen to update the executive mansion. Trump commented Monday that approximately 150 years’ worth of paint had already been scraped off the pillars, adding that letting the buildup remain would only worsen the condition. No official details have been released about the scope or cost of the column work.
