UPDATE: Tenafly Police on April 24th release a video of traffic stop.

Caren Z. Turner, a Democratic lobbyist from Tenafly, has resigned as a commissioner from the Port Authority of New York and New Jersey, after an investigation was opened into what agency officials would only describe as "profoundly disturbing conduct."

Officials would not disclose the circumstances, but two sources with knowledge of the investigation said it involved her intervention in a recent traffic stop in connection with her daughter. Both said Turner apparently flashed her Port Authority badge in an effort to intercede with police officers on the scene.

In a statement on Monday morning, the agency said: "The Port Authority has zero tolerance for ethics violations. This is the basis of the tough, systematic integrity reforms the Port Authority has implemented over the past year. Immediately upon learning of allegations that Commissioner Turner violated the Board's newly-enacted Code of Ethics, an Inspector General investigation was begun. The investigation revealed conduct that was profoundly disturbing. After Commissioner Turner became aware of the investigation, she resigned."

Even before the announcement, Turner's name and photo had already been removed from the Port Authority website.

Turner, who was appointed to the unpaid Port Authority position by former Gov. Chris Christie in March of 2017, submitted her resignation last week.

In her letter to Gov. Phil Murphy, she said she was resigning, effective immediately, saying she was "pleased to have played a role in the Port Authority's vital mission."

At her home Monday afternoon, a car was parked in the driveway, but no one answered the door.

According to her company bio, she served on finance committees for Hillary Clinton and Gov. Jon Corzine. She had been chair of the Port Authority's Governance and Ethics Committee.
