“It was greed. He just wanted money,” Robert Curington, 72, told The Post during a two-day interview at his North Carolina home, detailing for the first time how Sharpton stepped into the FBI’s trap — and was then forced to become a federal informant.

Sharpton has said he showed interest in the drug deal only because he feared the undercover agent was armed. He also claimed that he snitched for the feds — as first reported by The Smoking Gun this week — because the mob was threatening him.

Curington called all of that a tall tale.

He instead provided a detailed account of how Sharpton wined and dined a man he thought was a South American drug lord — and said Sharpton met him not just once, but three times.
