An NYPD cop from Staten Island is under review after posting racist diatribes on social media including one that called Mayor de Blasio’s wife a “former crack addict,” sources said.
Detective Gregory Gordon, who works at the 121st Precinct, is under fire after making a series of racist and anti-Muslim remarks on Facebook, according to law enforcement sources.

In one screed from Nov. 2014, Gordon was furious about a story reported by The Post that said the city’s first lady Chirlane McCray did not trust NYPD Commissioner Bill Bratton.
“Who cares what this former crack addict says!” Gordon wrote, according to a source.

McCray vehemently denied that she made the remarks.
Gordon, who has removed the entire Facebook page from the Internet, is being looked at by the NYPD who has told cops to “exercise good judgement” when using social media.
“The comments made by Gregory Gordon do not in any way represent the views of the New York City Police Department,” read a statement from the NYPD.
Gordon could not be reached for comment Thursday night.
