The assistant security director in charge of screening at Newark Liberty International Airport has resigned, federal officials confirmed yesterday, amid a scandal involving the leaking of test questions to candidates seeking high-level security jobs at the airport.

Gerard A. Grandinetti, a veteran of military and government service who was the No. 3 official in the airport’s 1,100-member screener detail, resigned Friday night, according to Mark Hatfield Jr., the director of security for the U.S. Transportation Security Administration at Newark.

Hatfield said, “He chose to resign for personal reasons,” declining to elaborate.
