A New Jersey legislative committee filed court papers Wednesday to compel compliance with its subpoenas by two figures implicated in last September’s closure of local access lanes to the George Washington Bridge.

The Legislative Select Committee on Investigation seeks declaratory judgments that Gov. Chris Christie’s former chief of staff, Bridget Kelly, and his former campaign manager, Bill Stepien, are acting in violation of valid subpoenas. Both have invoked the Fifth Amendment right against self-incrimination.
