The Senate judiciary committee agreed after Ford publicly testified about her allegations that the FBI conduct a supplemental background check to examine those allegations before the full Senate voted on his nomination.
The investigation was hampered, Whitehouse said, by executive branch delays, reluctance to answer even basic questions, and often incomplete answers.
Ford was not interviewed, the report said, even though her attorney repeatedly contacted the FBI directly to request the FBI interview her.
A lawyer for Ramirez provided lists of suggested witnesses to the FBI, including a list of 20 additional witnesses likely to have relevant information who Ramirez suspected could corroborate her account.
The alleged incident was separate from others that became public during the investigation but bore similarities to the allegations made by Ramirez. Stier notified the Senate and the FBI about his account, according to media reports, but the matter was never investigated by the FBI.
Stier, who runs a non-profit in Washington, has declined to discuss the matter with the Guardian. He is married to Florence Pan, who serves as a circuit judge on the US court of appeals, a post formerly held by the supreme court justice Ketanji Brown Jackson.
