Kavanaugh will also reunite with six of his former clerks on the US Circuit Court of Appeals for the District of Columbia who are now clerking for other justices.
Before hearing arguments on October 9, the justices turned aside appeals of a 2017 ruling authored by Kavanaugh on the lower court that struck down a 2015 environmental rule imposed under Democratic former President Barack Obama.
Kavanaugh is describing the confirmation process as "contentious and emotional" but says he has "no bitterness".
Kavanaugh's nomination was thrown into jeopardy when university research psychologist Christine Blasey Ford came forward with accusations that he had sexually assaulted her when they were teens in the Washington area.
Some analysts said the court's reputation could suffer as it becomes perceived as a political, rather than a legal, institution. That's because the Kavanaugh fight undoubtedly galvanized both parties' bases, and in places with key Senate races like Tennessee and North Dakota that's certainly not helpful, as anything that polarizes both sides equally in the national fight will only help Republicans in Republican strongholds.
The scene Tuesday morning contrasted sharply with a loud demonstration on Saturday, when chanting protesters climbed the normally off-limits Supreme Court steps and plaza.
Mr Kavanaugh denied the allegations and during a Senate hearing on September 27 accused Democrats of an "orchestrated political hit".
He said that "under historic scrutiny", Mr Kavanaugh was "proven innocent".
"I think a lot of Democrats are going to vote Republican", he said in his earlier comments outside the White House.
Nikki Haley Resigns as United Nations Ambassador, Report Says
Trump said that Haley told him six months ago about her plans to take time off after serving as ambassador for a year or two. Haley's personal finances are detailed in her public financial disclosure as the USA ambassador to the United Nations.
With justices seated by seniority, President Donald Trump's two appointees will flank the Supreme Court bench, Justice Neil Gorsuch at one end and Kavanaugh at the other. Justice Samuel Alito spoke at his swearing-in as well.
Kavanaugh joins the Supreme Court today after he was sworn in at a private ceremony on Saturday and a public ceremony on Monday, report the Wall Street Journal and the Washington Post in stories here and here. "Why don't we follow" the court's 2010 precedent on defining physical force, as it applied to the current petition, he wanted to know. Kavanaugh has also hired four clerks, all women, the first time that has happened.
Ultimately, every Democrat voted against Kavanaugh except for Sen.
After an extra Federal Bureau of Investigation probe - which media reports say was drastically curtailed by the White House - also found nothing new, Kavanaugh was finally voted into the coveted post. Joe Manchin of West Virginia.
Trump has now put his stamp on the court with his second justice in as many years.
"I´ve always been told it´s the biggest thing a president can do and I can understand that", he said. Yet Kavanaugh is joining under a cloud. Outside groups are culling an unusually long paper trail from his previous government and political work, with the National Archives and Records Administration expected to release a cache of millions of documents this month.
President Trump has praised his US Supreme Court pick.
This is all just hypothetical at this point, but McConnell would be in a different position than Biden was in 1992, or Schumer was in 2007, or McConnell himself was in 2016, since Republicans would control the Senate and the White House. The victory is a boon for Republicans who are looking to hold on to majorities in the house and Senate.
