"I believe [Kavanaugh] is a good man", Murkowski said Friday.
Murkowski called her personal consideration of which way to vote on Kavanaugh an "agonizing decision", but said that a judge "shall act at all times - not just sometimes when you're wearing your robe" in the way the Judicial Code directs.
The final Senate vote is expected Saturday, but enough senators have committed to backing him after a tumultuous political battle inflamed by allegations by California professor Christine Blasey Ford that Kavanaugh sexually assaulted her when they were teenagers in the early 1980s.
With the political world holding its breath, Collins spoke of a lack of "corroborating evidence" to back up Ford's claims that Kavanaugh was the man who assaulted her more than three decades ago. "Threats or other attempts to bully her will not play a factor in her decision making whatsoever", Annie Clark said in a statement before the senator announced her support for Kavanaugh.
The campaign to fund her future opponent passed the $2 million threshold right around the time the senator announced at the end of Friday's floor speech that she would vote to confirm. Democrats argue that Trump picked Kavanaugh, in part, because he is likely to vote to overturn that ruling.
Confirmation of Kavanaugh would give Trump a clear win in his drive to cement conservative dominance of the high court, a bitter outcome for Democrats who could not get their own liberal nominee confirmed due to Republican delaying tactics in 2016. She said that false news reports have also been spread through social media to discredit Kavanaugh, adding that "dark money" is being used to fund anti-Kavanaugh efforts, without elaborating.
But after the Federal Bureau of Investigation released its report late Wednesday, after less than a week of investigating, Flake said it had found "no additional corroborating information" against Kavanaugh. Democrat Joe Manchin voted for cloture, which meant that Vice President Pence did not have to be brought in to break a tie.
"Who wants to run for Senate in Maine?"
If confirmed, Kavanaugh would tip the balance on the court to a 5-4 majority in favour of conservatives in possible legal battles ahead over contentious issues such as abortion rights, immigration, and Trump's attempt to ban transgender people from the USA military. He said, "I believe he will rule in a manner that is consistent with our Constitution".
Democrats meanwhile condemned the investigation - the parameters of which were reportedly set by the White House - as preordained.
Jocelyn Sigue was one of a number of visitors who wrote a note about Supreme Court nominee Brett Kavanaugh to Sen.
In a twist, Murkowski said she will state her opposition but vote "present" as a courtesy to Kavanaugh supporter Sen. 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.
Murkowski and Manchin were two of the final holdouts on how they would vote on Kavanaugh's confirmation, along with Republican Sens. Kavanaugh's nomination as a replacement for retiring justice Anthony Kennedy was controversial from the start - but the initial focus was exclusively on the conservative views held by the married father of two.
