David Wildstein, an official at the Port Authority of New York and New Jersey at the time of the tie-ups on the George Washington Bridge in 2013, pleaded guilty to two counts of conspiracy.

He said that he came up with the plans along with Bridget Kelly, who was Christie’s deputy chief of staff, and Bill Baroni, who was Christie’s top appointee at the Port Authority.

He said they orchestrated the scheme to punish the Democratic mayor of the town of Fort Lee, at the foot of the bridge, for not endorsing Christie’s re-election bid. He said they also agreed to cover it up by claiming the lane closings were part of a traffic study.
