The George Washington Bridge between New York and New Jersey

Chris Christie is linked through emails and text messages to a seemingly deliberate plan to create traffic gridlock in a town at the base of the bridge after its mayor refused to endorse Christie for re-election. "Time for some traffic problems in Fort Lee," Christie aide Bridget Anne Kelly wrote in an Aug. 13 email to David Wildstein, a top political appointee at the Port Authority of New York and New Jersey, which runs the George Washington Bridge connecting New Jersey and New York City.

New Jersey Gov. Chris Christie addresses a gathering in Union City, N.J., Tuesday, Jan. 7, 2014. A top aide to Christie is linked through emails and text messages to a seemingly deliberate plan to create traffic gridlock in a town at the base of the George Washington Bridge after its mayor refused to endorse Christie for re-election. Christie, who has denied any knowledge of the plan, released a statement late Wednesday. “What I've seen today for the first time is unacceptable. I am outraged and deeply saddened to learn that not only was I misled by a member of my staff, but this completely inappropriate and unsanctioned conduct was made without my knowledge. One thing is clear: this type of behavior is unacceptable and I will not tolerate it because the people of New Jersey deserve better. This behavior is not representative of me or my Administration in any way, and people will be held responsible for their actions.” (AP Photo/Mel Evans)
