Ax falls amid Newark TSA chaos

Nine security screeners at Newark Airport are being fired and 30 more are under investigation after federal officials found serious lapses, The Post has learned.

“Several of their screeners were sleeping on the job or not screening bags properly,” an internal memo says. The probe began last fall.

TSA spokesman David Castelveter confirmed a probe “involving possible screening-protocol violations by TSA officers at Newark.”

The latest embarrassment to the agency took place Saturday, when a JFK Airport terminal had to be evacuated and hundreds of passengers marched back through security because one agent failed to realize a metal detector had been unplugged.
