President Trump warned Monday that anyone caught vandalizing the National Mall and the adjacent Lincoln Memorial Reflecting Pool faces years in prison.

“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 wrote on Truth Social. “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!” the president concluded.

Trump spoke out three days after former US Olympic canoer David Hearn was arrested and accused of vandalizing the recently renovated pool after he reached out and touched a detached piece of liner floating in the water.

Hearn faces a misdemeanor charge of destruction of government property and is due in court July 9.
