Federal authorities are investigating the vandalism of the National Mall in Washington, D.C., where unidentified individuals used a chemical agent to kill and discolor grass into the shape of the numerical code "86 47." The markings, positioned to be visible from the Washington Monument’s webcams, appeared ahead of public celebrations for President Donald Trump’s 80th birthday. While the code is a recognized political protest symbol, the White House and federal investigators are evaluating whether the act constitutes property damage or a targeted threat against the president.
What is the origin of the “86 47” protest code?
The "86 47" code functions as a hybrid of restaurant slang and political messaging. According to historical usage, "86" originated in the 1930s American food service industry to indicate that an item was out of stock or that a patron had been ejected from an establishment. In modern political discourse, the number "47" refers to the 47th President of the United States, Donald Trump.
Critics of the president use the phrase "to 86" as a synonym for removing someone from office or canceling a political project. Similar numerical protest codes have been used in previous administrations, such as "86 45" during Trump’s first term and "86 46" in reference to President Joe Biden.
Why do federal authorities view the code as a potential threat?
The interpretation of the code shifts from political dissent to criminal threat depending on the context of the verb "to 86." While the term is standard in the service industry, law enforcement officials note that in criminal or organized crime contexts, the phrase can imply a lethal directive to eliminate an individual or make them "disappear."
The administration’s sensitivity to the code intensified after former FBI Director James Comey posted an Instagram image in May 2025 featuring shells arranged to form "86 47." At the time, then-Deputy Chief of Staff James Blair characterized the post as a "signal to terrorists and hostile regimes to kill the president." Following that incident, Comey was questioned by the Secret Service and later faced charges in April 2026 related to alleged threats against the president. Comey has maintained that the post was a spontaneous reaction to finding the shells on a beach and denied any intent to incite violence.
How does the law distinguish between protest and criminality?
The legality of the "86 47" code is currently a subject of judicial scrutiny. Earlier in 2026, a federal judge ruled that the organization Accountability Now USA could display the numbers on flags near the National Mall, citing protections under the First Amendment. The court determined that the code, when displayed on signs or clothing, is generally interpreted as a call for constitutional removal or electoral defeat rather than physical violence.
However, the incident on the National Mall is being treated differently by authorities because it involves the destruction of federal property. Because the markings were created by intentionally killing the grass with chemicals, the perpetrators face potential charges for property damage. The Secret Service is currently conducting a dual investigation: one for the vandalism itself and a secondary review to determine if the specific placement and timing of the message constitute a credible security threat to the president.
Did you know?
The term "86" is so deeply embedded in American English that it is used in almost every professional kitchen, yet its exact etymology—whether it comes from a specific bar’s address or a menu item number—remains a subject of debate among linguists.

Pro Tip
When monitoring political discourse, distinguish between protected speech (such as banners or slogans) and criminal acts (such as vandalism or trespassing). The venue of the expression often changes the legal threshold for intervention by federal agencies.
Frequently Asked Questions
Is the "86 47" code illegal to display?
No. A federal judge previously ruled that displaying the code on flags or signs is protected under free speech laws, as it is viewed as a form of political protest.
Why is the National Mall incident being investigated as a threat?
Authorities are examining the act because it involved the destruction of federal property and was strategically placed to be visible during a high-security presidential event. The context of the "86" slang—which can imply lethal elimination—is being weighed against the intent of the protesters.
What are the potential penalties for this act?
The individuals responsible could face federal charges for the destruction of government property. If the investigation concludes that the act was a credible threat against the president, additional charges related to security and safety could follow.
