New Jersey Governor Chris Christie reacts during a news conference in Trenton January 9, 2014. Christie on Thursday fired a top aide at the center of a brewing scandal that public officials orchestrated a massive traffic snarl on the busy George Washington Bridge to settle a political score. Christie told a news conference he was stunned and heartbroken by revelations that his staff was behind the traffic jam designed to punish a local mayor who declined to endorse Christie’s re-election bid.
