Rep. Andy Harris (R-Md.), who has repeatedly flouted the magnetometers that were installed near the House chamber after the Jan. 6 attack on the U.S. Capitol, set off the metal detectors while trying to enter. When an officer with a metal detector wand scanned him, a firearm was detected on Harris’s side, concealed by his suit coat. Police refused to let Harris in, and the officer signaled a security agent that Harris had a gun on him by motioning toward his own firearm.

HuffPost witnessed the interaction and later confirmed with a Capitol official that Harris was carrying a gun.

HuffPost watched Harris try to get another member to take the gun from him so he could go vote. The member, Rep. John Katko (R-N.Y.), told Harris he didn’t have “a license” and refused to hold the weapon for him.

HuffPost also heard Harris complain to some fellow members that he had asked his staff to remind him about the screenings and they hadn’t.
