Someone vandalized one of America’s most treasured public spaces with what officials are calling a threat against the president — and the investigation is just getting started.

Story Snapshot

The numbers “86 47” were found burned or etched into the grass on the National Mall near the Washington Monument on June 11, 2026.
U.S. Park Police launched a vandalism investigation, collected grass samples for testing, and the cause of the markings has not yet been confirmed.
The Department of the Interior called it “deranged vandalism” and said any threat against the president is taken very seriously.
The incident happened days before President Trump’s UFC Freedom 250 event at the White House and his 80th birthday weekend.

Anti-Trump Message Appears on the National Mall

On the morning of June 11, U.S. Park Police officers spotted large numbers — “86 47” — burned or discolored into the grass on the West Lawn near the Washington Monument. The markings were so large they were visible from a webcam mounted on top of the monument. Police say they first noticed the numbers before noon. The numbers stretch between the Washington Monument and the World War II Memorial, right in the heart of the nation’s most visited public space.

The slang term “86” has long meant to remove or get rid of something. In some contexts, it can mean to eliminate or kill. Since Trump is the 47th president, officials and commentators quickly read the message as anti-Trump. Park Police roped off the area Thursday afternoon, and National Guard members directed the public away from the grass. Authorities collected grass samples for lab testing, but as of the investigation’s opening, the exact cause of the discoloration had not been confirmed.^[1]

White House and Interior Department Respond Forcefully

The Department of the Interior did not mince words. A spokesperson called it “deranged vandalism” and said it “will not be tolerated.” The statement added, “Any threat against the President is taken very seriously by the Department, and our U.S. Park Police will investigate this incident and hold those responsible accountable.”^[3] The White House also weighed in, with a spokesperson stating that “anyone who engages in or endorses political violence or assassination culture must be condemned in the harshest terms possible.”

The timing made the incident even harder to ignore. President Trump was set to host a Ultimate Fighting Championship event at the White House just days later, on his 80th birthday weekend. Federal authorities are already on heightened alert for political threats. The U.S. Secret Service deferred all questions to U.S. Park Police, which confirmed the investigation is active and ongoing.^[15]

The Comey Connection Adds Serious Weight

This is not the first time “86 47” has landed someone in legal trouble. Former Federal Bureau of Investigation (FBI) Director James Comey was charged with two federal counts after posting a photo on social media showing seashells arranged to read “86 47.” The Department of Justice charged Comey with making threats against the president. He faces up to 10 years in prison if convicted and has denied the post was meant as a threat.^[10] That case set a clear precedent — federal officials treat this specific phrase as a potential threat, not just political speech.

The man is David Hearn, 67, a Bethesda resident and former Olympic cyclist. U.S. Park Police arrested him Friday near the Lincoln Memorial Reflecting Pool on a misdemeanor charge of destruction of government property.

He reached into the pool and touched…

The National Mall vandalism case follows a broader pattern of “86 47” messages showing up at protests and public spaces across the country. A federal judge ruled separately this month that the phrase on a protest flag outside a federal courthouse was protected free speech. But defacing federal property is a different matter entirely. No suspect has been named in the National Mall case, and the forensic results from the grass samples have not yet been released. The investigation remains open, and authorities say they intend to hold whoever is responsible accountable.^[1]
