Overview
- Federal officers discovered the large numbers on the National Mall on Thursday and opened an active investigation after aerial images showed the markings near the World War II Memorial.
- U.S. Park Police collected grass samples for laboratory testing and cordoned the site while National Guard personnel and other responders assisted at the scene.
- Aerial photos show the 8 and 7 most clearly while the 6 and 4 are faint, and the message was primarily visible from height rather than from ground level.
- The sequence has been politically charged all year, drawing a DOJ indictment in April against James Comey for a separate use and a recent federal ruling that said the numbers alone may be protected speech.
- Officials warn the marking raises security concerns ahead of large events on the Mall, and the Secret Service has said it will help if investigators identify a suspect.
