June 12 (UPI) -- Federal authorities launched an investigation into a possible threat against President Donald Trump after "8647" -- a number combo used to signify opposition to Trump -- was found imprinted into the grass on the National Mall in Washington.
The probe into the numbers, distinguishable as brown grass along a significant section of the Mall to the east of the World War II Memorial, is being led by the U.S. Park Police with a spokesperson saying tests were being conducted on samples of the grass to determine the cause of the discoloration.
A source in law enforcement told CNN that the Secret Service would join the investigation once a suspect had been identified.
The White House strongly criticized those responsible.
