Government's star witness set to take stand in Bridgegate trial

NEWARK, N.J. — A former official who pleaded guilty in the George Washington Bridge lane-closing case and is expected to be the government's star witness is set to testify.

Attorneys say David Wildstein is one of the next three witnesses who could testify Friday in the trial of two former allies of Republican New Jersey Gov. Chris Christie.

Wildstein pleaded guilty last year to orchestrating traffic jams in 2013 to punish a Democratic mayor who didn't endorse Christie. Christie wasn't charged.

Wildstein and Christie attended high school together. Wildstein was hired by the Port Authority of New York and New Jersey to a position created for him.

Earlier Friday, jurors are expected to hear from Matt Mowers (MOW'-ers), a former campaign staffer who sought an endorsement from Fort Lee Mayor Mark Sokolich (SAHK'-oh-lich).
