Wildstein pleaded guilty last year to orchestrating traffic jams in 2013 to punish a Democratic mayor who didn't endorse Gov. Chris Christie. The former high-ranking official at the Port Authority who attended high school with Christie, testified that Christie was told about the traffic in Fort Lee on the third day of the gridlock during a Sept. 11 memorial event.
