TSA stopped the man with a 9-millimeter handgun in his backpack at Terminal C last Saturday.
The Port Authority was alerted and then confiscated the weapon.
Authorities say he was employed by a company at the airport. His employee badge has since been taken away and he is no longer employed at Newark.
The penalty for bringing a weapon to a TSA checkpoint is as high as $15,000.
