Legal experts say the George Washington Bridge traffic jam that was apparently engineered by New Jersey Gov. Chris Christie's allies could lead to criminal charges of conspiracy or official misconduct.

Also, those involved in the lane closings could be charged with perjury or obstruction if they lied to or misled investigators or if they produced documents after the fact that were designed to thwart an investigation.

Federal prosecutors and both houses of the New Jersey Legislature are investigating the scandal, which broke wide open last week with the release of emails and text messages suggesting that a top Christie aide ordered the lane closings in September to punish the Democratic mayor of Fort Lee.

The mayor did not endorse Christie for re-election.
