The Architect of the Capitol, a federal agency that oversees maintenance of the US Capitol Complex, is responsible for the port-a-potty cover-up just ahead of President-elect Donald Trump's inauguration.
"The AOC is in the process of covering or removing signage on the portable toilets to bring them into compliance with Capitol Grounds restrictions on advertising," Justin Kieffer, spokesman for the Architect of the Capitol, told NBC News. "Our staff determined that the Gene's Johns signs can be easily peeled off. The Don's Johns signs cannot and are being covered with tape."
Thousands of port-a-potties are being installed on the National Mall for Inauguration Day and word spread Friday that blue tape was being placed over "Don's Johns" on the toilets, the name of one of the port-a-john suppliers.
Don's Johns Sanitation Services, of Virginia, has has long supplied portable restrooms for major outdoor events.
Under the blue tape, the company's name is clearly visible upon close inspection, but would be blocked for a wide-angle view by a camera.
