From the Associated Press:

LITTLE ROCK, Ark. – David Huckabee, a son of Republican presidential candidate Mike Huckabee, was arrested at an Arkansas airport Thursday after a federal X-ray technician detected a loaded Glock pistol in his carry-on luggage.

“I removed the bag and asked Mr. Huckabee if he knew what he had in the bag,” Little Rock police officer Arthur Nugent wrote in a report after being summoned to a security checkpoint. “He replied he did now.”
