A public swearing-in ceremony will take place on Monday in the White House's East Room.
The U.S. Senate confirmed Brett Kavanaugh's nomination to the Supreme Court on Saturday by a vote of 50-48.
That leaves Chief Justice John Roberts, the most moderate, as the new man in the middle - but still very much a conservative at heart.
It represents the culmination of a decades-long project by the conservative movement to construct a like-minded majority on the Supreme Court which has been a defining and unifying cause in successive congressional and presidential campaigns.
Throughout the day, Trump also kept his focus on the opposition, saying Kavanaugh had withstood a "horrible, terrible attack" that "nobody should have to go through". She then voted to advance Kavanaugh's nomination and has said that she will vote yes on Kavanaugh' during the full Senate's confirmation vote on Saturday.
Asked last week if she could have mistaken her attacker, Ford testified that she is "100 percent" certain it was Kavanaugh.
He has vehemently denied all allegations of sexual misconduct against him when he was in high school and college.
On Friday, in the moment that made clear Kavanaugh would prevail, Collins delivered a speech saying that Ford's Judiciary Committee telling of the alleged 1982 assault was "sincere, painful and compelling".
"This is one of the reasons I chose him is because there is no one with a squeaky clean past like Brett Kavanaugh".
"Took a week - but that extra week was a great thing", he said, referring to the supplemental FBI background investigation into the allegations against Kavanaugh.
Ahead of the Senate vote, protesters vented their rage on the steps of the US Capitol.
Trump's aggressive defense of Kavanaugh - and more recent attacks against his female accuser - have resonated particularly with white working-class men, who are a shrinking voting bloc nationally but remain a critical segment of Trump's political base.
Brett Kavanaugh Drops Harvard Teaching: Must-See Details
Kavanaugh was good enough for Elena Kagan - a female nonetheless, and one of the most left-leaning justices on the Supreme Court. According to The Wall Street Journal's Rebecca Ballhaus, Kavanaugh has taught at Harvard for the past decade, since 2008.
But she also spoke of the country's bitter divisions, and how American politicians and the Trump administration have done little to douse the flames.
Collins reviewed the results of the investigation, which included testimony from 10 different witnesses but not from Ford or Kavanaugh, on Friday.
The Senate voted Friday to end debate on Kavanaugh's nomination, setting the stage for a final vote in the chamber Saturday evening.
During his confirmation hearing, Kavanaugh tried to dispel fears that he would rule on a partisan basis, arguing that "a good judge must be an umpire - a neutral and impartial arbiter who favors no litigant or policy". But two other key senators, Senators Susan Collins of ME and Joe Manchin of West Virginia, voted for cloture, with Collins indicating that she would announce her final decision on how to vote by 3 pm on Friday.
Their vote, which was paired because Daines could not attend, maintains the same two-vote margin and does not change the outcome.
Kavanaugh's nomination sparked protest across the Capitol, which continued Saturday.
The Democrats are still smarting from the previous Supreme Court appointment.
When Vice-President Mike Pence, who presided over the vote, exited the Senate, he was loudly booed and heckled by onlookers outside until he ducked into his limousine.
Before the vote, Senate Minority Leader Chuck Schumer, a Democrat from NY, urged Americans who were dissatisfied with the confirmation to go to the polls in November and "vote".
Another group of protesters stormed towards the doors of the nearby Supreme Court building with raised fists. McConnell extolled Kavanaugh as a "superstar, a serious scholar" who is "legendary for his preparation and possesses the qualifications, the temperament and judicial philosophy" to be a brilliant justice. "A vote to confirm Judge Kavanaugh", McConnell continued, is a vote about the Senate itself, where "the facts matter" and the "politics of personal destruction do not win the day". They went through it, and they went through it seven times.
Her hearing sparked a supplemental Federal Bureau of Investigation probe into his background, which created a week long delay of the vote. Lisa Murkowski of Alaska was the only Republican who did not vote to confirm; rather than a "no" vote, she voted "present".
