A person with knowledge of the case says a former political ally of New Jersey Gov. Chris Christie is scheduled to plead guilty for his role in politically motivated traffic tie-ups near the George Washington Bridge in 2013.

David Wildstein was an official at the Port Authority of New York and New Jersey at the time of the tie-ups. He arrived at federal court in Newark around 8:45 a.m. Friday with his attorney. A court hearing is set for 11 a.m.

The person wasn't authorized to release the information before the hearing and spoke on condition of anonymity.

The U.S. attorney's office will hold a news conference at 1 p.m.

Two of the three access lanes in Fort Lee to the bridge were closed for four mornings in September 2013, causing jams throughout the streets.

Wildstein resigned months later amid revelations that he ordered lanes closed in Fort Lee for political retribution.

Federal prosecutors have announced a court proceeding involving the 2013 traffic jams on the George Washington Bridge, an investigation that has loomed over New Jersey Gov. Chris Christie as he considers a presidential run.

An 11 a.m. court hearing is scheduled for Friday, and the U.S. attorney's office will hold a news conference at 1 p.m.

The office, which Christie led before stepping down in 2008 to run for governor, has not said who will appear in court or any other details.

Two of the three access lanes to the bridge in Fort Lee were shut down for four mornings in September 2013, causing massive delays.

An aide to Christie emailed a Port Authority of New York and New Jersey official, "Time for some traffic problems in Fort Lee," initiating the shutdowns.
