An invitation-only area known as the “John Wayne Saloon” inside the North American Aerospace Defense Command was shuttered last week, following an investigation by USA Today.

The reporting showed alcohol was available inside Building 2 on Peterson Space Force Base in a room locked by keypad marked by a John Wayne poster and unknown to senior commanders. Those who shared the story with USA Today on condition of anonymity “expressed unease, dismay or disgust.”

Gen. Glen VanHerck, commander of NORAD and Northern Command, acted immediately after the paper brought forward the allegations.

“Based on your inquiry, what I did was immediately direct a walkthrough of all spaces in the command with the intent to corroborate any of the allegations,” VanHerck told USA Today. “We did find the John Wayne poster outside a door. Behind the locked door, what we found was an office space with a refrigerator that did contain some alcohol. We did find some beer, refrigerator and some hard liquor.”

An investigation will determine if drinking inside the headquarters affected national security, VanHerck said. He told USA Today he did not sense a compromise.

The area with alcohol was a standard office space with access to classified networks for planning purposes, he said.

NORAD is charged with protecting the United States and Canada. Northern Command was set up in 2002 following the Sept. 11, 2001, terror attacks.

The joint command responded to The Gazette, reiterating that VanHerck immediately conducted an investigation into the allegations.

“There is no indication of any impact to operations, and NORAD and USNORTHCOM continue to conduct our missions,” a spokesperson for the command said.

The two commands were thrust into the international spotlight earlier this year by a Chinese spy balloon that was shot down near the coast of South Carolina in February after floating over the U.S. and Canada. The event drew congressional interest in boosting funding for homeland protection.

VanHerck has been pressing for investments into the joint command such as over-the-horizon radar to detect hypersonic weapons.
