A large set of numbers, “86 47,” is carved into grass on the National Mall in Washington, D.C., according to reports from multiple outlets. The markings were found on Thursday, days ahead of expected large crowds for an upcoming UFC event outside the White House. One outlet says the “86 47” has been interpreted by the Trump administration as a threat directed at President Donald Trump, who has a birthday in the days leading up to the UFC event. Both accounts describe the same location and timeframe, noting that the carving is visible from camera views of the area. The reports do not provide additional evidence about who made the marking or the specific meaning of the numbers beyond the administration’s stated interpretation. It is also not clear from the available coverage what immediate law enforcement or security responses are underway. The incident adds to ongoing attention on the security and public order preparations around high-profile events in the capital.
