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.
