The Transportation Security Administration confirms it is pursuing disciplinary action against six baggage screeners at New Jersey's Newark Liberty International Airport -- including some suspected of sleeping during part of their shifts.

The employees have been cited for alleged failure to follow procedures and have been suspended from screening duties while the cases proceed. TSA employees have the right to appeal any disciplinary action.

Officials also confirmed Tuesday that another baggage screener at Newark is facing possible dismissal for allegedly failing on Dec. 22 to adequately check two bags that raised concerns, causing two planeloads of luggage to be rescreened.

The union representing the workers tells The Associated Press it cannot comment on ongoing cases.
