While Trump apologized on behalf of the nation for "the bad 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".
The president also falsely asserted that Kavanaugh was "proven innocent".
Kavanaugh will take part in an entirely ceremonial swearing-in two days after he officially became a member of the high court and following a bitter partisan fight over his nomination.
The other eight justices were all in attendance for Monday's swearing-in by retired justice Anthony Kennedy at an entirely ceremonial event.
Before hearing arguments on Tuesday, 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 former President Barack Obama regulating a potent greenhouse gas linked to climate change. It comes just in time to motivate evangelicals and social conservatives to turn out to vote in November elections that will determine control of Congress. And Saturday's vote was also a victory for the Senate, and for the integrity of our institution.
Kimmel had some choice words about Trump's performance during Monday's televised ceremony, especially when the president proclaimed that Kavanaugh had been "proven innocent" of Dr. Ford's assault allegation.
During a speech in Florida earlier today, Trump denounced the accusations against Kavanaugh as "a hoax" perpetrated "by people that are evil". Americans opposed his confirmation 51 percent to 41 percent, according to a CNN poll conducted October 4-7. Collins spoke to "60 Minutes" Sunday and said of the woman who accused Kavanaugh of sexual assault: "I believed that a sexual assault had happened to her".
The new justice dived into his new job, asking a handful of questions in the first arguments of the day following a traditional welcome from Chief Justice John Roberts, who wished Kavanaugh "a long and happy career in our common calling".
Other major polls reflected similar sentiment.
"The Senate confirmation process was contentious and emotional".
"I mean you're not exactly on a winning streak here in ACCA cases", Justice Samuel A. Alito Jr. told the lawyer arguing for the federal government.
One recent video that has gone viral showed two young protesters dancing around a lone, elderly, pro-Kavanaugh protester silently holding up signs.
The latest justice to join the bench, Neil Gorsuch, spoke a year ago during his swearing-in at the White House Rose Garden.
Protesters demonstrate on first day with newly sworn in Associate Justice Brett Kavanaugh on the court at the Supreme Court in Washington, U.S., October 9, 2018. He had already hired four law clerks, all women.
"I take this office with gratitude and no bitterness. And he's continued to do that inside the White House". The president later hosted a reception at the White House for Sotomayor, as he did a year later with Kagan.
Judicial Crisis Network, the "dark money" group that spent millions promoting Supreme Court Justice Brett Kavanaugh's confirmation effort, announced a new "six-figure TV and digital ad campaign" Tuesday in support of Sen.
