The number "8" is seen on the lawn on the National Mall in Washington, DC, on June 12, 2026. US Park Police opened an investigation on June 11 into giant markings of the numbers "8647" -- which have been associated with opposition to President Donald Trump -- on the grass of the National Mall. A spokesperson for the Department of the Interior, which manages the National Mall in downtown Washington, described the incident as "deranged vandalism" and said it "will not be tolerated."
