Authorities Investigate Mysterious 86 47 Markings on National Mall

U.S. authorities are investigating grass discolorations spelling "86 47" on the National Mall in Washington, D.C., discovered June 11, 2026. The Trump Administration describes the markings as a threat or allusion to presidential assassination, while the U.S. Park Police have collected grass samples to determine the cause of the staining.

Aerial images taken June 11 show the discoloration near the World War II Memorial, positioned between the Washington Monument and the memorial. The photos reveal a visible number 8 and traces of the numbers 6, 4, and 7. The discovery occurred days before Donald Trump's birthday on June 14 and a scheduled Ultimate Fighting Championship (UFC) event at the White House.

The timeline of the discovery varies by source. The Washington Post reported that the numerals were visible on June 9, 2026. Reuters reported that one of its photographers observed the markings shortly before the U.S. Park Police and National Guard arrived on the scene. The markings were also captured by a live camera mounted atop the Washington Monument.

Why is the "86 47" phrase significant?

The numbers combine restaurant industry slang with a political reference. According to Merriam-Webster, "86" is slang meaning "to throw out," "to get rid of," or "to refuse service to," though the dictionary notes it has more recently been used to mean "to kill." The number "47" is used as a reference to Donald Trump, the 47th U.S. President.

The phrase has previously been used to signal opposition to the President. In 2025, former FBI Director James Comey posted an image on Instagram of seashells arranged to spell "86 47." Comey was indicted in April 2026 for allegedly making a threat against the President. Comey has maintained his innocence and cited free speech as his defense.

How are authorities responding to the markings?

The Interior Department characterized the National Mall incident as "deranged vandalism." The department stated that any threat against the President is taken seriously and that U.S. Park Police will hold those responsible accountable.

A spokesperson for the U.S. Park Police stated they have not yet determined the cause of the discoloration. The agency confirmed that a probe is underway and grass samples have been collected for laboratory testing.

Anyone who engages in or endorses political violence or assassination culture must be condemned in the harshest terms possible. They should also immediately seek psychiatric help to treat their severe and debilitating case of Trump Derangement Syndrome that has warped their brains and made them sick in the head.

What is the legal precedent for these symbols?

There is a conflict between the current administration's interpretation of the symbol and recent judicial rulings. While the Interior Department views the markings as a threat, a federal judge recently ruled otherwise regarding similar imagery.

Earlier in June 2026, District Judge Randolph Moss stopped the National Park Service from taking action against Accountability NOW USA. The progressive group had displayed an "86 47" flag during a permitted demonstration near the George Meade Statue in D.C. Although the display prompted a Secret Service investigation, Judge Moss disagreed with the government's assessment.

It is difficult to fathom how the NPS (or the Secret Service) could have concluded that a reasonable observer would view the flag as a true threat.

The National Mall has served as a frequent site for symbolic protests against the President. In 2025, a statue depicting the President holding hands with convicted sex offender Jeffrey Epstein was placed on the grounds. In March 2026, the "No Kings" protests saw demonstrators march from Arlington, Virginia, to the National Mall to denounce the President.
