Fort Lee Mayor Mark Sokolich arrives for a news conference at Fort Lee, N.J., City Hall, Thursday, Jan. 9, 2014. Sokolich called it “appalling” that the traffic jams appear to have been deliberately created at the George Washington Bridge for three days in September 2013. Chris Christie, in an attempt to avoid damage from a scandal that could undermine his presidential prospects, said Thursday he has fired a top aide who apparently created traffic jams as part of a political vendetta. Christie denied any knowledge of the scheme.
