A former ally of Gov. Chris Christie has admitted to his role in politically motivated traffic tie-ups near the George Washington Bridge in 2013.

David Wildstein admitted Friday that he caused traffic problems to punish Fort Lee Mayor Mark Sokolich because he refused to support Christie's 2013 re-election effort.

Wildstein is cooperating with prosecutors' investigation of the lane closures and has told a judge he plans to plead guilty.

The former official at the Port Authority of New York and New Jersey admitted that he talked about how the bridge's access lanes could be used as leverage against Sokolich with former Christie chief of staff Bridge Kelly and Port Authority executive Bill Baroni.

He says they agreed to ignore communications form Sokolich about the traffic jams.

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.
