President Trump said he is "100 percent" certain that Christine Blasey Ford named the wrong person when she accused Brett Kavanaugh of sexual assault in testimony during his Supreme Court nomination hearings.
It reflects a high water mark of the Trump presidency: Republican control of the White House, the Senate, the House of Representatives and the judiciary's top court.
Brett Kavanaugh was sworn in as US Supreme Court justice on Saturday, the court said, after a deeply divided US Senate confirmed him to the court and Republicans dismissed accusations of sexual misconduct against the conservative judge.
Democratic politicians appear eager to try and channel voter anger over the confirmation of Brett Kavanaugh to voter turnout in November.
Protesters swarmed the streets of Washington, and rushed to the steps of the Supreme Court to.
"Justice Kavanaugh met with his four law clerks, all women - a first for the Supreme Court - in chambers that had until recently been occupied by Justice Samuel A. Alito Jr., who has moved to Justice Anthony M. Kennedy's old chambers", the Times reports.
"I stand before you today on the heels of a tremendous victory for our nation, our people and our beloved Constitution", he told supporters after signing Kavanaugh's commission aboard Air Force One.
A separate, public swearing-in ceremony is planned for 7:00 pm (2300 GMT) Monday in the White House's East Room.
During the vote, other protesters shouted "shame" from the public gallery and Vice-President Mike Pence had to call for order to be restored.
Democrats charged that the White House prevented the Federal Bureau of Investigation from doing a thorough probe that might have run down leads, and multiple Yale classmates of Kavanaugh's tried to contact the Federal Bureau of Investigation but say they were not interviewed.
Judge said in a statement he did not remember the incident but FBI agents spoke to him for three hours during their investigation.
Democrats said Kavanaugh's partisan defense of himself, in which he said he was victim of a "political hit", was enough itself to disqualify him from the court.
"We need healing", Murkowski told reporters afterwards.
Two Republican waverers, Susan Collins and Jeff Flake, finally made a decision to back the judge.
His ascent to the Supreme Court was thrown into doubt last week after university research psychologist Christine Blasey Ford testified that he had sexually assaulted her at a Washington area gathering in the early 1980s.
Kavanaugh's nomination seals a conservative majority on the nine-seat high court, possibly for decades to come.
Rice, a Democrat, had hinted her interest in a Senate run in a one-word tweet on Friday, responding "me" to an open question about who wanted to run against Collins. "So I think even before you start focusing on questions about his truthfulness before a Senate committee, you've got to focus on the urgency of the work over the next 30 days, and that's where my focus is", Booker said. "The country is badly polarised, and they elect people to represent them here who have the same point of view that they do", he said recently.
