The Republican-controlled Senate today voted 51-49 in favour of ending debate over the 53-year-old’s nomination to the highest court in the United States.
Two US senators, Republican Lisa Murkowski and Democrat Joe Minchin, broke party lines by voting against their parties.
The divisive vote on the judge’s lifetime role will come as a bitter blow to hundreds of anti-Kavanaugh protestors who rallied against him on Capitol Hill yesterday.
His confirmation will be announced at 3pm ET on Saturday, after a final vote is taken on the senate floor.
If nominated, he will swing the court to a 5-4 majority in favour of conservatives voting on contentious issues such as abortion and immigration rights.
President Donald Trump tweeted his delight at the results saying: “Very proud of the U.S. Senate for voting “YES” to advance the nomination of Judge Brett Kavanaugh!”
Who is Brett Kavanaugh and what is the controversy surrounding him?
Mr Kavanaugh is a US former attorney and federal appeals court judge.
Following his nomination, he was accused of sexual assault by Doctor Christine Blasey Ford in an incident dating back to 1982 when she was 15 and he was 17.
The university professor alleges Mr Kavanaugh pinned her down while drunk, tried to remove her clothing and covered her mouth after she screamed.
Mr Kavanaugh vehemently denies the allegation and that he also drank to the point of losing his memory.
Two other women, Deborah Ramirez and Julie Swetnick, have since come forward also accusing Mr Kavanaugh of sexual misbehaviour in the 1980s.
The married father-of-two also denies their allegations.
He was announced as President Trump’s Supreme Court judge nomination to replace retiring Associate Supreme Court Justice Anthony Kennedy on July 9.
At a Judiciary Committee hearing last week to discuss the allegations, Mr Kavanaugh appeared angry and emotional at times.
He has since admitted in a Wall Street op-ed piece he may have been too emotional at times” as it ”reflected my overwhelming frustration at being wrongly accused”.
Mass protests have been held over the Kavanaugh vote, with more than 100 people arrested on Thursday outside Capitol Hill.
Actress Amy Schemer and model Emily Ratajkowski were among those arrested by police.
Mr Kavanaugh’s controversial nomination has been criticised by advocates of the MeToo movement, campaigning for an end to sexual harassment of women.
Mr Trump wrote on Twitter yesterday the FBI, which is investigating the claims against the judge, wrote in a report the allegations against Mr Kavanaugh were “totally uncorroborated”.
