Gary J. Walters was appointed White House Chief Usher in 1986. According to Walters, “I was standing at the state floor of the White House adjacent to the staircase that comes up from the ground floor. The police officers and I felt a cool rush of air pass between us and then two doors that stand open closed by themselves. I have never seen these doors move before without somebody specifically closing them by hand. It was quite remarkable.” Other staff member report that White House doors throughout the building close by themselves.
