The World War II Memorial on the National Mall in Washington, D.C., was vandalized Thursday with bright pink spray paint reading “Clean hands, dirty money.” The memorial’s fountain was also tampered with, overflowing with bubbles, prompting U.S. Park Police to block off the area.

In 2016, the memorial was vandalized by someone protesting the controversial Dakota Access Pipeline.

An Army veteran named Debra Mortensen, who visited the memorial, expressed her offense: “I was offended because people fought and died for our country, and it’s dishonoring our country and all we’ve been through.”

DC resident Ahmed Cisse described the incident as shocking: “It’s kind of shocking for us to see that.” A woman named Priscilla, who traveled from New Jersey, said: “It’s really sad. It’s really sad to see that we can’t even experience it.”

A passerby exclaimed: “Ah geez, that’s sh—y.”

Interior Department spokesman Cody Sargent condemned the vandalism as “disgusting” and stated it was “pathetic to deface a memorial to our WWII heroes.” He added: “Thankfully, I know our incredible [National Park Service] will get this cleaned up for the majority of Americans who love their country.”

The Interior Department vowed to find the person responsible for the act.

Additionally, the incident followed alleged vandalism to the new swimming pool liner coating the nearby Lincoln Memorial Reflecting Pool.
