President Donald Trump said late Saturday that multiple people have been arrested for vandalizing the nation’s newly refurbished Reflecting Pool and that significant repairs will be needed as he demanded “years in jail” for the perpetrators.

“What these terrible Vandals have done is a true affront to both Presidents George Washington and Abraham Lincoln, and should be dealt with accordingly,” Trump wrote on his Truth Social post platform in a series of posts.

“The United States Park Police have arrested multiple individuals for vandalizing our Nations magnificent Reflecting Pool. Who would do such a thing?” he asked. “These are very serious crimes having to do with the destruction of National Monuments. Years in jail!”

Trump said extensive repairs will be needed, starting with the likely draining of the water.

“We met with contractors today, will probably be forced to release and drain much of the water in order to do the necessary repairs, but will have them done as quickly as possible,” he wrote. “What they have damaged does not even include the earlier killing of a large amount of grass which was, by far, the least of it. They took some form of knife or blade, and put a 250 foot long gash into the beautiful facade of what took so much work, competence, and money to build and complete. They also poured corrosive and destructive chemicals into the Pool.”

The president lamented the damage to a project he personally oversaw and had just completed.

“The Reflecting Pool was never so beautiful as it was just one week ago, even going back to 1922 when it opened. We are very proud of what we have done with this magnificent structure, and we will get it repaired, quickly, to an equal level of Beauty,” he promised.
