Giuliani: Christie's Career 'Completely At Risk' If He Isn't Telling the Truth

ABC News(NEW YORK) -- Sunday on This Week, former New York City Mayor Rudy Giuliani defended New Jersey Gov. Chris Christie, but warned that the Garden State governor is putting his political future in jeopardy should evidence surface that he had any knowledge of his aides’ alleged actions in the George Washington Bridge scandal.

Christie has become embroiled in a escalating and damaging political scandal over the closing of traffic lanes from Fort Lee, N.J. to the George Washington Bridge, which resulted in major backups for days last September. Christie has denied any knowledge of his aides’ alleged actions and fired a senior aide for her involvement in the affair.

“If, for some reason, it’s not true, the man has put his political career completely at risk if it turns out there is some evidence that he knew about it,” Giuliani told ABC News’ Martha Raddatz. “He’s taken the complete risk that his political career is over. I don’t think he’d do that if there’s any suggestion he knew about this.”

This week — during a press conference that lasted close to two hours — Christie apologized profusely for the actions of his aides and took responsibility for the events, adding that he was misled about the circumstances involving the lane closures. He also fired Bridget Anne Kelly, a deputy chief of staff to the governor who sent a now infamous email to David Wildstein of the Port Authority of New York and New Jersey, saying “Time for some traffic problems in Fort Lee”.

It remains unclear precisely why the aides worked to close the lanes, although the emails suggest some political calculation was involved.
