The number of guns found by TSA officers last year was the highest annual total for the agency since it was created in the wake of the 9/11 terror attacks.

The Transportation Security Administration found a record-setting 6,737 guns at airport security checkpoints in 2023, the agency announced Wednesday. The number of firearms found by TSA officers last year surpassed the previous year’s record of 6,542 guns and was the highest annual total for the agency since it was created in the wake of the 9/11 terror attacks.

The agency said approximately 93% of the weapons were loaded, which TSA Administrator David Pekoske said was “concerning.”
