New Jersey Gov. Chris Christie was interviewed last month by federal prosecutors probing the George Washington Bridge scandal, NBC affiliate WNBC has confirmed – one more bit of bad news this week that could complicate Christie’s potential 2016 presidential bid.

“Gov. Christie made clear from day one that he and his administration would fully cooperate with all appropriate inquiries,” Christie spokeswoman Maria Comella said. “That’s exactly what he has done and will continue to do, and he is very much looking forward to this matter’s conclusion.”

The other bad news for Christie this week:

• The Wall Street Journal reported that federal prosecutors “have subpoenaed Gov. Chris Christie’s re-election campaign for documents relating to government meetings that were allegedly canceled with Jersey City’s mayor after he declined to endorse the governor, according to people familiar with the matter.” More: “The subpoenas, sent by U.S. Attorney Paul Fishman, are another sign that the yearlong probe into former allies of Mr. Christie has broadened beyond matters directly related to the George Washington Bridge lane closures.”
• NJ.com also reported that Dallas Cowboys owner Jerry Jones – who paid for Christie’s travel to last Sunday’s Cowboys-Lions NFL playoff game – “is a part-owner of a hospitality company recently awarded a lucrative Port Authority hospitality services contract.” Christie, as well as New York Gov. Andrew Cuomo oversee the Port Authority. A Christie spokesman later said that Christie and Jones only became friends after the Port Authority’s bid procurement process.
