The Pentagon has a media room, where officials brief the press in front of television cameras. It of course has a greenroom.
The reality of television is that if you go on it you need to wear makeup. If you don't, the intense lighting they use will either wash your complexion out and make you look dead, it'll hit the oil on your skin and look like a mirror, or it'll pass through the top layer of your skin, light up the capillaries in your face and make you look like some sort of a monster. If you're wearing a layer of foundation the light will reflect off the makeup and you'll look...well, slightly more human in the case of Hegseth.
In the old green room they had a table and chairs, pictures of former Defense secretaries on the wall, and a small mirror hanging on the back of the door for you to use to prepare yourself for the camera.
What they did is remove the table and chairs, take the mirror off the door, and then hang up a proper makeup mirror and makeup lights that they already had in a storeroom.
