And on Monday evening he was the guest of honour at a ceremonial swearing-in at the White House.
President Donald Trump apologized to Supreme Court Justice Brett Kavanaugh for "the bad pain and suffering" he and his family were "forced to endure" during his confirmation process, at a ceremonial swearing-in event at the White House on Monday evening.
While Trump apologized on behalf of the nation for "the awful pain and suffering" Kavanaugh and his family had suffered and declared him "proven innocent", the new justice assured Americans that he would be fair and was taking the job with "no bitterness".
Ms Pelosi says she will file a Freedom of Information Act (FOIA) request to make public the confidential FBI investigation into the claims against Justice Kavanaugh.
He used the swearing in ceremony to announce he had "no bitterness" over his bruising nomination process as he vowed to be a "team player".
Justice Kavanaugh also faces more than a dozen judicial misconduct complaints over his public statements as a nominee to the Supreme Court.
Kavanaugh took his seat at the end of the bench to Roberts' far left, a visible manifestation of a moment that Republicans have dreamed of for decades, with five solidly conservative justices on the court, and Democrats have dreaded. The two networks combined on Saturday reached just over 2 million viewers for the Senate vote.
The U.S. Senate voted to confirm Kavanaugh Saturday after weeks of hearings looking into his background.
Kavanaugh asked several questions during lively oral arguments involving a federal sentencing law for repeat offenders, three days after being confirmed by the Republican-led Senate despite being accused of sexual assault. Americans opposed his confirmation 51 percent to 41 percent, according to a CNN poll conducted October 4-7.
Kavanaugh's new "team" smiled as they joined Kavanaugh Tuesday morning.
Other major polls reflected similar sentiment. He has also played basketball in the Supreme Court's gym, which is jokingly referred to as the "highest court in the land".
During Kavanaugh's confirmation process, dozens of women had dressed up in similar costumes to represent the TV show's depiction of women living under a dystopian fundamentalist regime.
Kavanaugh is expected to vote with his conservative colleagues on the bench, even on some hot-button issues where Kennedy served as a swing vote. "So I don't know how people are going to react to it". "If Justice Roberts sits on the complaints, then they will reside in a kind of purgatory and will never be adjudicated", said New York University law professor Stephen Gillers.
"What was done last night at the White House was a political rally", Clinton told CNN's Christiane Amanpour in an interview set to be broadcast Tuesday night.
Kavanaugh officially took the oath in a more hurried, private procedure Saturday, but the White House version late Monday gave the Trump administration a chance to perform the equivalent of a victory lap on live television. It wasn't as entertaining as a question from Roberts, who described grasping some cash and asking his clerks to pull it from his hand as a kind of impromptu test of a criminal law definition.
