TRENTON, N.J. (AP) — A former appointee of Gov. Chris Christie who directed lane closures that caused massive traffic tie-ups in northern New Jersey is reiterating that he is ready to talk with lawmakers if he can be granted immunity from prosecution.

But lawyer Alan Zegas tells The Associated Press former Port Authority of New York and New Jersey official David Wildstein has not received any immunity offers.

Documents he provided a legislative committee investigating the September lane closures on an approach to the George Washington Bridge make it appear that the closures were designed as political retribution.

He appeared before a legislative committee last week but refused to answer any questions.

A committee investigating what happened could reveal the names Friday of the 17 people and three organizations who are being issued subpoenas.
