Chris Christie accused of misuing Sandy storm relief fund He told CNN on Monday that the inspector general of President Barack Obama's housing department was carrying out a full audit, after a preliminary review uncovered enough evidence for him to proceed. Mr Christie insisted last year that there was "nothing political about the ads," adding: "I hope that what they do is they bring people to the Jersey Shore." Yet critics cited them as fresh evidence of politically-motivated misbehaviour by Mr Christie's office during his campaign for re-election as governor, which he won in a landslide last November. Emails released last week showed that aides to Mr Christie closed down roads to inflict four days of traffic gridlock in the town whose Democratic mayor had declined to support his re-election. Four Christie allies have already been fired or resigned over the saga, which threatens to badly damage the 51-year-old's status as the early frontrunner for the Republican party's 2016 White House bid. It is being investigated by members of the New Jersey assembly, while the state's US attorney - the top federal prosecutor, appointed by Mr Obama - is also looking into the possibility of criminal charges. Mr Christie, who previously insisted his team had nothing to do with the road closures, said he was "embarrassed and humiliated" by the disclosures, but insisted he had been lied to by his aides.
