Administration officials apparently hoped to prevent any surprises from sinking his nominations. In 1971, Deputy Attorney General Richard Kleindienst directed the FBI to conduct investigations of witnesses who were planning to testify at a Senate hearing against Rehnquist's confirmation. Fifteen years later during the Reagan administration, the FBI was enlisted to conduct background checks on witnesses who were scheduled to testify against Rehnquist's nomination to become chief justice.
