Donald Trump Issues New Threat on ‘8647' Message on National Mall Lawn

President Donald Trump on Monday issued a new warning over vandalism on the National Mall, linking the "8647" marking in the grass to broader damage reported near the Lincoln Memorial Reflecting Pool.

The "8647" message appeared on the National Mall lawn on June 11, when authorities first responded to reports of the numbers etched into browned grass and launched an investigation into the cause. The reflecting pool issues began shortly after its early June reopening, when a more than $14 million renovation was completed and algae blooms and peeling blue paint surfaced within days. The two developments have unfolded as officials investigate the vandalism and make arrests tied to activity around the pool.

In a new post on Truth Social, Trump warned that federal authorities would enforce strict penalties for the “destruction.”

“Of the MANY Statues and Fountains that we rebuilt, renovated, cleaned, and fixed, the only one that was Vandalized was the Reflecting Pool, which is being taken care of, ASAP!” Trump posted on Truth Social on Monday morning. “It has been given a 300 foot long gash, chemicals have been illegally placed in the water, and the beautiful new grass field has been destroyed with a gigantic 86 47 chemically carved into it (Probably inspired by Dirty Cop, James Comey!). Please remember that there is a 10 year prison sentence for the destruction, or even the attempted destruction, of such things – Which will be fully enforced! Thank you for your attention to this matter.”
