Reporters were told the governor would only answer questions about a major problem at a water treatment plant, according to the Newark Star-Ledger.
Yet one reporter proceeded to ask an unrelated question involving the state legislature, as seen in video of the press conference from Monmouth County.
Christie, cutting him off, said: “Did I say on topic? Are you stupid? On topic, on topic. Next question.”
As the reported tried to follow up, the Republican governor again interjected and ended the press conference.
“Thank you all very much, and I’m sorry for the idiot over there. Take care,” he said before walking away.
