TSA: Passenger caught smuggling knives through airport security

Riley said the incident was an example of what TSA does at airports across the country.

"Every single day our officers stopping weapons like these from moving from one side of the checkpoint to the other," he told The Hill. "This is certainly unusual because there were 13 weapons, but in a way it's an example of what happens at our airports every day." 

The news of the foiled knife-smuggling comes as members of Congress harshly criticized the TSA Wednesday for reports of breaches of airport perimeter security.

The House Oversight Subcommittee on National Security held a hearing Wednesday where lawmakers berated TSA Assistant Administrator John Sammon.
