After a racially offensive sign was seen at a New Jersey United States Post Office, an official investigation has been launched to find the person responsible.  

According to USPS Postal Inspector Greg Kliemisch, the sign posted at a Flemington location read, "March is national stop blaming white people month! Accept responsibility for your own bad choices. Hug a white person!"

Kliemisch said the sign was put up sometime Thursday and was taken down in the afternoon by employees, NJ.com reports.

Kliemisch said posting signs on the building is strictly prohibited and he could not say if the location where the sign was placed had surveillance cameras.

In an open Facebook group, Flemington Councilwoman Betsy Driver criticized the sign and said that it is “sad and not a reflection of our town.” Someone who first posted the sign to the group included “lmao,” but they deleted it soon after.

“This is disturbing. And sadder is that the poster posted it on FU (since deleted) as an “lmao” item. Racism in our town exists, and the racists have been emboldened in the past year to fly their hateful flags a bit higher and yell a bit louder,” Driver wrote.

Kliemisch said Friday the investigation was in the early stages. It was not immediately clear what potential consequences the sign hanger might face if caught.
