New Jersey lawmakers, continuing their investigation of allegations of political retribution as the motive to create traffic jams near the George Washington Bridge last year, heard Thursday from an aide to Gov. Chris Christie. Here is a timeline of important dates in the scandal:
Sept. 16, 2010: Mayor Mark Sokolich of Fort Lee, New Jersey, meets with Port Authority of New York and New Jersey Deputy Executive Director Bill Baroni to discuss traffic problems related to the George Washington Bridge, one of the world's busiest spans. The Port Authority runs the bridge; access lanes to it are in Fort Lee.
Nov. 9, 2010: In a letter to Baroni, Sokolich details his town's traffic problems and asks for more help from the Port Authority to direct traffic amid gridlock. He notes that problems worsen when some toll lanes are shut down on weekends.
Spring 2013: The Christie re-election campaign asks Sokolich, a Democrat, to consider endorsing the Republican governor. Sokolich says later he never gave an answer to Christie's campaign.
Aug. 12: Bridget Kelly, then Christie's deputy chief of staff, calls another Christie aide, Matt Mowers, to confirm that Sokolich would not be endorsing the governor.
Aug. 13: Kelly emails Christie ally David Wildstein, director of interstate projects at the Port Authority. Kelly writes: "Time for some traffic problems in Fort Lee." Wildstein responds: "Got it."
Sept. 9: Instead of the usual three approach lanes to the bridge from Fort Lee, commuters find only one open that morning. Traffic is gridlocked for four days.
Sept. 13: Port Authority Executive Director Patrick Foye orders the approach lanes be reopened, writing in a memo: "I believe this hasty and ill-advised decision violates federal law and the law of both states."
Nov. 5: Christie, considered a possible 2016 presidential contender, is re-elected governor.
Nov. 25: Baroni appears before the New Jersey Assembly Transportation Committee, which had begun an investigation, and apologizes for what he acknowledges is the agency's failure to communicate to local officials about the gridlock.
Dec. 6: Wildstein's resignation is announced, effective Jan. 1, 2014.
Dec. 9: When asked about the lane closures at a news conference, Christie jokes, "Unbeknownst to everybody, I was actually the guy out there. I was in overalls and a hat. I actually was the guy working the cones."
Dec. 13: Christie denies the lane closures were politically motivated and criticizes Democrats for exploiting the closures and "all the other politics swirling around it." He announces Baroni's resignation and says Wildstein's resignation would be effective that day.
Jan. 8, 2014: Email and text message exchanges between Wildstein and Kelly are made public, including the damning "time for some traffic problems" communication.
