TRENTON, N.J. — Republican Gov. Chris Christie fired one of his top aides on Thursday and apologized repeatedly for his staff's "stupid" behavior, insisting during a nearly two-hour news conference that he had no idea anyone around him had engineered traffic jams as part of a political vendetta against a Democratic mayor.
"I am embarrassed and humiliated by the conduct of some of the people on my team," Christie said as he addressed the widening scandal, which could cast a shadow over his expected run for the White House in 2016.
The famously blunt governor fielded dozens of questions from reporters with uncharacteristic patience and at times a sorrowful tone.
Christie, who had previously assured the public that his staff had nothing to do with the September lane closings that caused major backups at the George Washington Bridge, said he fired Deputy Chief of Staff Bridget Anne Kelly "because she lied to me" when he demanded weeks ago that anyone who knew anything about the episode come forward.
The gridlock in Fort Lee delayed emergency vehicles, school buses and countless commuters for four days.
Kelly was the latest casualty in the scandal. Two other top Christie appointees have resigned in the past few weeks.
The investigation broke wide open on Wednesday, with the release of emails and text messages that suggested Kelly arranged the traffic jams to punish Fort Lee's mayor for not endorsing Christie for re-election.
