TPM has someone in the courthouse in Newark relaying the events.
Link if you want the news straight from them.
The headline item: David Wildstein is pleading guilty to and factual claims he is making as part of his plea include the decision to shut down the lanes to the bridge was done to punish Fort Lee Mayor Mark Sokolich for his failure to endorse Gov. Christie's reelection campaign, and the first day of school was chosen as the day to begin the lane closures specifically to maximize the pain on city residents and thus on Sokolich as part of a scheme of political payback.
Wildstein also admitted to conspiring with two other Christie allies, Bill Baroni at the Port Authority and Bridget Kelly, who was Christie's deputy chief of staff.
In other words: the scandal now goes right into Christie's office.
