But Manchin said little Thursday and Friday to indicate what his final vote would be, after studying the Federal Bureau of Investigation report addressing allegations of sexual misconduct leveled against the nominee.
But she didn't look especially happy about it Friday.
Senator Susan Collins - a maverick member of Trump's Republican party - and her Democrat counterpart Joe Manchin said allegations that Brett Kavanaugh had sexually assaulted a fellow teenager almost four decades ago were unproven.
"I want other countries to take note and not do what we have done", said Tay Anderson, who was among the handful of men who attended the rally.
She told reporters that Mr Kavanaugh is "a good man" but maybe "not the right man for the court at this time". Christine Blasey Ford, a Palo Alto University professor, said he tried to rape her in high school, and Deborah Ramirez said he exposed himself to her when they were college classmates. That procedure lets a senator offset another's absence without affecting the outcome, and would allow Kavanaugh to win by the same two-vote margin he would have received had both lawmakers voted. She was re-elected in 2016. And they said his record and fuming testimony at a now-famous Senate Judiciary Committee hearing showed he lacked the fairness, temperament and even honesty to become a justice.
Their declarations of brought the number of senators publicly supporting the 53-year-old judge - who has faced accusations of sexual assault - to 51 in the 100-member chamber. As the clerk read the names in alphabetical order, all eyes were on Murkowski.
Ms Murkowski sat solemnly during the roll call and whispered "No" when it was her turn to vote. But she is also under great pressure from Kavanaugh opponents in ME, where activists have been crowdfunding a hypothetical Democratic opponent for 2020 should she vote "yes". The two huddled in deep conversation.
The vote gave Trump his second appointee to the court, tilting it further to the right and pleasing conservative voters who might have revolted against GOP leaders had Kavanaugh's nomination flopped. "Susan Collins just made a huge choice to ignore her constituents and survivors (of sexual assault)".

Pogba says 'not allowed' to talk after Man United stalemate
United were held to a scoreless draw by the Spaniards on Tuesday, heaping further pressure on Portuguese manager Jose Mourinho . Ander Herrera, another midfielder, was used in a three-man back line as Tottenham won 3-0 at Old Trafford in August.
Scholes 'surprised' Mourinho remained in job, says manager is 'embarrassing' club
The pressure is now piled onto the club and Jose even further as they extended their winless run to four games. He said: "I am pleased with the effort, I am pleased with the commitment, I am pleased with the improvement".
At the time, he called the 1973 Supreme Court landmark case Roe v. Wade settled law, saying that it "has been reaffirmed many times over the past 45 years" and that the most prominent and most important case was Planned Parenthood v. Casey in 1992.
Several Democrats conferred with Murkowski as well, including Minnesota Sen.
Murkowski has a Democratic counterpart in a similarly precarious position: West Virginia Sen. Manchin is trying to hold off his Republican opponent, Patrick Morrissey, in a state Trump won by about 43 percentage points.
The Senate Judiciary Committee confirmed his nomination on party lines, after which his nomination moved to the Senate floor.
Manchin, who faces a competitive re-election next month in a state Trump overwhelmingly carried in 2016, voted to advance Kavanaugh's nomination in a key procedural vote earlier Friday.
Facing an uphill primary battle, Flake is retiring at the end of this term, making his role in the Kavanaugh confirmation likely one of the last significant actions of his Senate career.
The procedure, which involves Murkowski being recorded as "present" in the vote as opposed to "no", is unusual enough that Senate Majority Leader Mitch McConnell's office issued an explanation to reporters on Friday night.
