A New Jersey legislative committee is ordering current and former aides to Gov. Chris Christie and two officials at the Port Authority of New York and New Jersey to testify in its probe on politically motivated traffic jams last year near the George Washington Bridge.

Lawmakers announced Tuesday that they had issued subpoenas to former Christie aide Christina Genovese Renna, current press secretary Michael Drewniak, Port Authority Commissioner William Schuber and executive director Patrick Foye.

Assemblyman John Wisniewski says the panel has received documents that answer some questions but raise others. He says the best way to get answers is to question officials under oath.

All four are being told to appear before the legislative committee in May.

Christie has denied any involvement in orchestrating the jams.
