In 1991, the administration of Republican President George H.W. Bush directed the FBI to gather facts after Anita Hill brought sexual harassment allegations against Republican Supreme Court nominee Clarence Thomas. The FBI then compiled a report about the claims that included interviews with Hill, Thomas and at least one witness and submitted it to the White House. The FBI investigation, took place after the confirmation hearing — as would be the case with nominee Brett Kavanaugh — but before the committee vote — as it would be with Kavanaugh. It took three days.
That matter was a claim of verbal sexual harassment.
