New Jersey Gov. Chris Christie is facing a controversy over whether his appointees deliberately caused traffic delays to exact political revenge. Democrats say lanes on the New Jersey side of the George Washington Bridge were reduced in September to punish the mayor of Fort Lee for declining to endorse Christie’s bid for re-election. Just one lane was operational over a four-day period, causing massive traffic jams. Two Christie appointees, one of them a high school friend, have resigned since the scandal broke. One of them has claimed the lanes were closed to conduct a traffic study, but it appears no study actually took place. Democratic Sen. Jay Rockefeller has asked the Department of Transportation to investigate. Christie has denied any wrongdoing and said he had no knowledge of the closures when they occurred.
