The chairman of the Senate judiciary committee says the FBI found “no hint of misconduct” in its investigation into Brett Kavanaugh.
The FBI have conducted a background investigation into sexual misconduct claims against the Supreme Court nominee.
Republican senator Chuck Grassley said he received a briefing from staff on the confidential report and says “there’s nothing in it that we didn’t already know”.
Mr Grassley said the FBI could not find any people who could “attest to any of the allegations” against Mr Kavanaugh and that there is “no contemporaneous evidence”.
He urged his colleagues to confirm the judge.
However, Democrats have complained that the FBI’s reopening of its Kavanaugh background check has been far too limited, leaving out contact with crucial potential witnesses.
Several US media publications reported that witnesses who believe the FBI should interview them over the allegations feel like they have been silenced.
Some claim they have been blocked from speaking to the Bureau, have sent unsolicited statements to the Bureau and to senators, or feel when they have been interviewed that no effort to corroborate their stories has been made.
Professor Christine Blasey Ford testified in front of the committee that Mr Kavanaugh, then aged 17, sexually assaulted her when she was aged 15 in Maryland in 1982.
Dr Ford testified that she could not remember the precise date or location of the alleged assault or how she got home afterward.
She testified that a drunken Mr Kavanaugh pinned her down, tried to remove her clothing and covered her mouth when she screamed.
Mr Kavanaugh denies any wrongdoing and an important vote on his future is expected to take place on Friday.
Earlier this week Donald Trump was criticised for imitating Dr Ford at a rally in Mississippi.
“What neighbourhood was it in? I don’t know. Where’s the house? I don’t know. Upstairs, downstairs, where was it? I don’t know. But I had one beer. That’s the only thing I remember,” Mr Trump mocked.
He went on to say: “A man’s life is in tatters.”
