New Hampshire Republican Party staffers arrived at work Thursday morning to find their Concord headquarters vandalized.
A rock had been thrown through a window and the word "Nazi" was spray-painted on the back of the building in a heart.
Concord Police are investigating and will determine whether the incident should be treated as a hate crime, Lt. Sean Ford told the Concord Monitor.
“We’re certainly looking for any help we could get from the public to get an idea of who might have done this,” Ford said.
A spokesman for the New Hampshire GOP did not immediately return The Hill's request for comment.
The state's Democratic Party issued a statement on Thursday condemning the vandalism, which the party's chairman called "inexcusable."
“Vandalism is unacceptable, it's inexcusable and it's wrong. The New Hampshire Democratic Party wholly condemns this criminal action and hopes the perpetrator is held accountable. There is no place for that in our politics," said Ray Buckley.
The vandalism comes as President TrumpDonald TrumpKinzinger welcomes baby boy Tennessee lawmaker presents self-defense bill in 'honor' of Kyle Rittenhouse Five things to know about the New York AG's pursuit of Trump MORE faces mounting criticism over his comments regarding white supremacist protests in Charlottesville, Va., on Saturday that turned violent.
Trump told reporters in a news conference Tuesday that "both sides" were to blame for the violence and suggested there were both good and bad people on both sides of the protest — which was organized by white supremacist and neo-Nazi groups and counterprotested by anti-fascist and anti-Trump groups.
Trump has denied suggesting there is "moral equivalency between the KKK, neo-Nazis & white supremacists" and the woman, a counterprotester, who was killed when a car allegedly driven by a man attending the rally drove into a crowd.
Both Democrats and Republicans have criticized Trump's remarks, which many have said fall short of a full-throated condemnation of hate groups.
