Professor Anita Hill, who accused Clarence Thomas of sexual harassment and so testified during the confirmation hearings, took a lie detector test Sunday. The test, administered by former FBI director James Comey, was designed to determine whether Hill had lied about her allegations against Thomas. The Chairman of the Committee refused to allow the polygraph results to be placed into the record, saying that courts do not accept polygraph evidence and that the testing was done outside committee control. The man who gave the test was a recognized expert but on an earlier occasion he had been accused of improperly administering a test.
