A senior aide to New Jersey Governor Chris Christie deliberately created a traffic jam to punish a mayor, a series of emails and text messages revealed.
The messages, obtained yesterday by the Associated Press and others, came amid an investigation into whether a huge traffic backup last year was retribution against the mayor of Fort Lee for not endorsing Mr Christie for re-election last autumn.
Mr Chirstie's deputy chief of staff Bridget Anne Kelly wrote in a message to David Wildstein: "Time for some traffic problems in Fort Lee," to which Mr Wildstein, a Christie appointee on the Port Authority of New York and New Jersey, responded: "Got it."
A few weeks later, he closed two of three lanes connecting Fort Lee to the busy George Washington Bridge, which runs between New Jersey and New York City.
The messages do not directly implicate Mr Christie in the shutdown, who said he was "outraged and deeply saddened" by the incident.
