After POTUS was finished torching Democrats and Ford, Kavanaugh spoke of being a "force for stability and unity". Kavanaugh denied the accusations.
The president - whose Republicans fear losing at least the lower chamber of Congress - predicted that Democrats would pay for their attempts to block the confirmation, especially during the lurid debate over decades-old sexual assault allegations. One of the two cases the court is hearing Wednesday involves the detention of immigrants, an issue on which Kavanaugh's vote could be key.
Justice Kavanaugh, who will be a conservative voice on the court, said he had "no bitterness", that he felt "gratitude" for eventually being confirmed, and that the Supreme Court was "not a partisan or political institution".
"On behalf of our nation, I want to apologise to Brett and the entire Kavanaugh family for the bad pain you have been forced to endure", Mr Trump said on Monday (Oct 8) during a ceremonial swearing-in at the White House.
"Every American can be assured that I will be an independent and impartial justice", Kavanaugh said in the White House East Room after a ceremonial swearing-in.
Trump continued: "And with that I must state that you, sir, under historic scrutiny, were proven innocent".
Speaking at a police convention in Orlando later, the president said the allegations against the justice were "brought about by people that are evil".
On Saturday, the Senate voted 50-48 in Kavanaugh's favor, with Sen.
The ranking member of the House judiciary committee, Jerry Nadler of NY, has said his party would investigate the sexual misconduct allegations against Kavanaugh if the Democrats reclaim the majority in the chamber.
Nikki Haley Said to Resign as United Nations Ambassador
Trump tweeted that he has a "big announcement with my friend Ambassador Nikki Haley in the Oval Office at 10:30 a.m". The Senate overwhelmingly confirmed her to the post in January 2017, by a vote of 96-4.
As he returned to the White House Monday from Florida, Trump anticipated that Kavanaugh's swearing-in would be a "big night". He claimed he was the first justice to have an all-female staff. Almost two-thirds, or 63%, of likely women voters said they will vote for the Democratic congressional nominee in November, compared to 33% of likely women voters who said they'll vote Republican.
"The reality is, right now, Republicans control the House and the Senate, and there's no way to do even an investigation unless we flip one of the houses", replied Booker, a Democrat seen as a potential presidential candidate in 2020.
Kavanaugh, Kimmel noted, was approved by the smallest margin of any Supreme Court Justice since 1881.
Kavanaugh will hear his first Supreme Court case, a day after President Trump swore in his nominee.
Senator Chris Coons of DE called impeachment talk "premature", while House Minority Leader Nancy Pelosi said it "would not be my plan" to impeach the justice.
Many observers have noted that Kavanaugh's confirmation itself represent a triumph of minority rule, in two senses.
The president said he had many friends who were Democrats, but that the party was pushing politics too far left.
All eight of the Supreme Court's other justices attended the White House ceremony, a show of collegiality by members of an ideologically divided court.
