A Department of Homeland Security office building in Washington, D.C. was vandalized with a hand-drawn swastika, officials said.

The Nazi symbol was discovered Friday on the third floor of the department’s Nebraska Avenue Complex, according to an email sent to staffers and reported by CNN.

“There is no room in the workplace for such symbols of hate,” wrote Brian Murphy, Principal Deputy Undersecretary for the Office of Intelligence and Analysis. “And there is no room in the workplace for those who ascribe to such a thing.”

The matter was referred to the department’s Inspector General, officials said.

One employee answered Murphy with sarcasm – and accidentally sent the message to the entire agency.

“As if leadership really cares,” the worker wrote. “I guess I should not be surprised.”

Murphy also used “reply all” to respond, “I do care.”
