Kavanaugh's passionate defense came after a university professor, Christine Blasey Ford, told the Senate Judiciary Committee that he sexually assaulted her 36 years ago.
The judge, however, has "unequivocally and categorically" denied Dr Ford's allegation and called himself a victim of "grotesque and obvious character assassination".
She described "uproarious laughter" by Mr Kavanaugh and his friend, whom she said was also involved in the alleged incident in a locked bedroom at a gathering of high school friends.
The Senate Judiciary Committee began meeting early Friday and was expected to narrowly vote in favor of Donald Trump's pick after key Republican Jeff Flake said he would back the judge, whose nomination would swing the high court solidly to the right.
He added: "Democrats' search and destroy strategy is disgraceful and this process has been a total sham and effort to delay, obstruct, and resist".
With the Senate Judiciary Committee holding a vote at 9:30 A.M. tomorrow, a Senate insider has told Townhall that Kavanaugh has the votes to make it out of committee and the votes to be confirmed on the floor for a seat on the U.S. Supreme Court. He did not specify whether he thought the Senate inquiry was sufficient or whether the FBI should investigate, as Democrats have asked.More news: Our opinion: Get vaccinated for flu season
REPUBLICAN SEN. TED CRUZ of Texas: "All three of those fact witnesses have stated on the record under penalty of perjury that they do not recall what she is alleging happening".
Republicans hold a narrow 51-49 majority in the Senate, and can only afford one defection in their bid to confirm Kavanaugh, assuming they secure no Democratic votes.
Ms Ford has said Kavanaugh friend Mark Judge was also in the room. But even if the panel deadlocks on whether to recommend the judge for confirmation, the full Senate could start taking procedural votes Saturday on Kavanaugh, setting up a final vote as soon as Tuesday.
The proceedings were shown all day on the nation's major TV networks, starting with Ford's unwavering account in the morning and Kavanaugh's equally emphatic response in the afternoon.
"Late Thursday, the magazine of the Jesuit religious order in the United States withdrew its endorsement of Kavanaugh, saying the nomination was no longer in the interests of the country and "should be withdrawn".
"I'm innocent. I'm innocent of this charge", Kavanaugh said.More news: Where would the Brewers and Cubs play NL Central tiebreaker?
But under the committee's procedures, the career prosecutor was limited to five minutes at a time, interspersed between Democrats' questions, creating a choppy effect as she tried piecing together the story. "This whole two-week effort has been a calculated and orchestrated political hit fueled with apparent pent-up anger about President Trump and the 2016 election", he said. The accusations are from incidents that were said to have happened in the 1980s.
"I believed he was going to rape me", she said in her opening statement.
In his first remarks about Ford's testimony, the president said she was "very compelling" and looked like "a very fine woman to me", calling her "a credible witness". "This is a national disgrace, the way you're being treated".
The decision to tap Mitchell comes as Republican senators insist that their committee staffers can handle an investigation that Democrats and Kavanaugh's accusers have said the FBI should be conducting.
"I am terrified", she said, her voice often quavering. "I intend to vote for you and I hope everybody who is fair-minded will", he told Kavanaugh. Democratic questioners are certain to ask uncomfortable questions about Kavanaugh's youth that could create defensive or combative moments.

However, despite being pressed repeatedly by Democrats to call for an FBI investigation into the claims of Ford and others, Kavanaugh declined to do so, saying instead: "I welcome whatever the committee wants to do". "This is the most unethical sham since I've been in politics", said Senator Lindsey Graham of SC.
