Jan. 9: During a nearly two-hour news conference, Christie apologizes for the lane closures but denies knowledge of them or a cover-up, saying he is "embarrassed and humiliated." He announces Kelly has been fired "because she lied" and that he is cutting ties with his former campaign manager, Bill Stepien. Meanwhile, U.S. Attorney Paul Fishman announces he will investigate whether any laws were broken. Also, six residents sue Christie, the state and the Port Authority, alleging they were harmed by the traffic jams. The same day, a judge rules that Wildstein must appear before lawmakers who issued a subpoena; he appears later that day but invokes his right not to incriminate himself and refuses to answer any of the lawmakers' questions.
March 27: Lawyer Randy Mastro, who was retained by Christie's office, releases a report that finds Christie and his remaining top staffers did nothing wrong regarding Fort Lee traffic and the bridge. "Governor Christie's account of these events rings true. It's corroborated by many witnesses, and he has conducted himself at every turn as someone who has nothing to hide," the report says. Democrats blast it as political propaganda.
March 28: Port Authority Chairman David Samson, a Christie appointee, announces his resignation from the board. His lawyer later says he will no longer cooperate with the lawmakers' inquest citing privacy concerns and his right not to self-incriminate.
April 9: A judge rules that Kelly and Stepien can invoke their right not to self-incriminate to avoid complying with the lawmakers' subpoena to provide documents.
May-June: Four Christie aides appear before the special joint legislative committee investigating the bridge scandal.
Wednesday: Assemblyman John Wisniewski, the committee co-chairman, says several people on its list of potential witnesses are off limits for now because they could also be important to the federal criminal investigation.
Thursday: Christie aide Regina Egea testifies in front of the committee that she did not alert any of her bosses when she learned about the closure of lanes leading up to the bridge in part because she believed someone else was trying to get to the bottom of it.
