U.S. law enforcement authorities have launched an investigation into an unusual, large-sized marking etched into the grass of Washington DC’s National Mall that spells out the numerical sequence 8-6-4-7, a code that has become associated with anti-Donald Trump rhetoric in recent political discourse.
For context, the two-digit number “86” has long circulated as American slang meaning to forcibly remove or eliminate a person or thing. Current Trump administration officials have publicly asserted that the full 4-digit sequence, which ends in 47—Trump’s official designation as the 47th U.S. president—functions as a coded call to incite violence against the sitting president.
The U.S. Park Police confirmed in an official statement that officers first responded to a formal report of vandalism at the site at approximately 11:30 a.m. Eastern Time Thursday, which translates to 16:30 GMT. As of the latest update, investigators have not yet confirmed what caused the discoloration of the grass that created the visible numbers. Officials confirmed that grass samples have been collected for forensic testing, and the probe remains active and ongoing.
Photographs captured at the site show clear markings for the numbers 8, 6, and 7, but the third digit 4 is faint and not distinctly visible in existing imagery. The location of the marking places it just a short distance from the National World War II Memorial, one of the most visited historic landmarks on the National Mall.
This ongoing investigation comes at a moment of already heightened political tensions, as federal prosecutors are currently pursuing criminal charges against former FBI Director James Comey over a separate social media post that featured the same 8-6-4-7 sequence arranged out of seashells on a beach. Comey faces multiple felony charges tied to allegations that the post constituted a criminal threat to kill President Trump. Comey has forcefully denied all wrongdoing, dismissing the prosecution as a blatant politically motivated attack targeting his opposition to the Trump administration.
The coded number sequence has been adopted repeatedly by Trump’s political opponents over the course of his second term, appearing at multiple anti-administration protests across the country. The faded marking on the National Mall, which is most notable for the clear visibility of the leading 8 compared to the other three digits, emerged amid a high-profile citywide beautification initiative for federal monuments and public spaces that is being personally led by Trump. The initiative includes $13.1 million in allocated funding—equal to roughly £9.6 million—for renovations to the Lincoln Memorial Reflecting Pool, as well as a controversial plan to construct a large commemorative arch decorated with gilded sculptures of iconic American symbols including lions and eagles.
