NEW YORK DAILY NEWS: New Jersey legislators probing the George Washington Bridge lane-closure scandal issued 18 new subpoenas Monday, including to the State Police aviation unit that handles Gov. Chris Christie’s helicopter travel. The latest batch of Bridgegate subpoenas — 20 were issued last month — will be sent to a host of officials in the governor’s office, as well as to executives at the Port Authority. Information gleaned from the subpoena to the aviation unit could shed light on Christie’s helicopter travel during the time the lanes were closed four days in September. Christie’s office said Monday the governor flew to the state capital after going to a 9/11 anniversary event in New York. Panel members, convened to probe the politically motivated lane closures on the George Washington Bridge in September, also voted to compel two former Christie aides to respond to earlier subpoenas. Ex-Christie campaign manager Bill Stepien and Christie’s now-fired deputy chief of staff Bridget Anne Kelly have both invoked their Fifth Amendment right against self-incrimination. MORE
