Newly released — and somewhat controversial — FBI files, dating from the former Chief Justice’s two confirmation battles in 1971 and 1986, disclose that William Rehnquist battled a painkiller addiction in the early ’80s while serving on the Court. “Doctors interviewed by the FBI told agents that when the associate justice stopped taking the drug, he suffered paranoid delusions. One doctor said Rehnquist thought he heard voices outside his hospital room plotting against him and had ‘bizarre ideas and outrageous thoughts,’ including imagining ‘a CIA plot against him’ and ‘seeming to see the design patterns on the hospital curtains change configuration.’ At one point, a doctor told the investigators, Rehnquist went ‘to the lobby in his pajamas in order to try to escape.’“
