In New Jersey, state lawmakers investigating the closure of lanes on the George Washington Bridge by an ally of Gov. Chris Christie are issuing 18 new subpoenas in the case, including to Christie’s office, members of his inner circle and the state police unit overseeing Christie’s helicopter travel. Christie fired a top aide last month after it emerged she ordered the lane closures in an apparent act of political retaliation. Christie’s former ally at the Port Authority, David Wildstein, has since claimed Christie knew about the lane closures at the time, a claim Christie has denied. Christie, who is head of the Republican Governors Association, is in Illinois today to raise money for his Republican colleagues. Amid the bridge scandal, none of Illinois’ Republican candidates for governor are expected to attend Christie’s events.
