“ The First Lady dabbled in astrology as far back as 1967. In 1981 [Joan] Quigley made Nancy a believer …. And from then on, no presidential public appearance was slated without the Friend's say-so. To this day, Nancy's Friend continues to influence the President's schedule. For the Reagan-Gorbachev Washington summit, she cast the charts of both men and determined
that 2 p.m. on Dec. 8, 1987, was the most propitious moment for them to sign the intermediate-range nuclear forces treaty. At Nancy's behest, the entire summit was built around that hour. For the upcoming Moscow summit, Gorbachev's chart (he is a Pisces) has been recast alongside Reagan's (Aquarius).”
“ [Former White House Chief of Staff, Donald] Regan and others make a compelling case that in 1986 and 1987 astrological influence dramatically reduced the presidency's effectiveness, at least partly, by keeping Ronald Reagan under wraps for much of the time. Nancy's intrusions in the scheduling process, Regan said in an interview with TIME last week, ‘began to interfere with the normal conduct of the presidency.’” (TIME, May 16, 1988)
