First Lady Nancy Reagan regularly consulted astrologer Joan Quigley from 1981 to 1989, using astrology to plan President Reagan's schedule, including meetings, speeches, and even the timing of the 1987 Intermediate-Range Nuclear Forces Treaty signing.
Quigley claimed she helped keep Reagan safe after his 1981 assassination attempt. The revelation caused controversy, but Nancy Reagan defended the practice, saying it gave her peace of mind.
Former Chief of Staff Donald Regan later wrote that "virtually every major move and decision" was cleared through astrology first.
