New Jersey Gov. Chris Christie, known for his candor, snapped at a reporter Saturday while taking issue with his question at a press conference.
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.
Christie, who is rumored to be a potential GOP vice presidential pick, has made headlines in the past for growing confrontational with reporters or audience members at events.
Mitt Romney, himself, teased Christie about his brash behavior Tuesday night when the two appeared together at a fundraiser.
"That man really is something, you know that? I was hoping someone in here would start to heckle him so I could watch him go to town here. But you know better, don't ya? What an extraordinary leader," Romney said, according to pool reports.
