A senior aide to New York City Mayor Bill de Blasio is under fire for posting a photo to Facebook of a sign that reads “f*** whiteness.”

The picture, posted on November 14, shows Lincoln Restler's parents and sister on the streets of New York protesting Donald Trump's election victory.

His sister is seen holding a sign with the vulgar slogan, while his parents' signs read "Black Lives Matter" and "Love."

Restler deleted the post after people began to criticize his sister's sign as vulgar, racist and inappropriate. Restler also deleted his Twitter account.

De Blasio spokesman Eric Phillips said the mayor was not initially aware of the picture and doesn’t believe it’s appropriate.

He added that Restler was spoken to but not sanctioned.

“He understands why people took offense to it, and it certainly didn’t represent his views,” Phillips said.
