WASHINGTON (AP) — Capitol Police arrested a Kansas man trying to enter a House office building with an unloaded gun.

Lt. Kimberly Schneider says police arrested Joshua Wheeler of Atchison, Kansas, Monday morning as he entered the Longworth House Office Building on Capitol Hill.

The 25-year-old Wheeler allegedly was carrying an unloaded Smith & Wesson 9 mm handgun. Schneider says he was charged with carrying a pistol without a license and an unregistered firearm, and was taken into custody.

Wheeler, 25, was a summer intern with Republican Rep. Lynn Jenkins. He was placed on temporary leave.
