The numerals were not discernible to people on the #NationalMall, who could only see a few brownish patches of grass near the WWII Memorial. The numerals seemed visible only from a tall vantage point, such as the top of the Washington Monument.
Multiple emergency vehicles could be seen encircling the grass around 1PM. A team of officers stood over brown patches in the grass, wearing gloves, & appeared to be testing the grass with materials from a yellow case.
Pedestrians were not permitted to walk on the grass, and a Park Service helicopter circled overhead.
…This month, a federal judge prohibited the National Park Service from taking action against the organization #AccountabilityNOW USA, which displayed an “#8647” flag as part of an ongoing permitted demonstration in Washington. The Secret Service started an investigation into a volunteer with the organization after the flag was displayed.
