“I stand here tonight, truly honored and humbled," Barrett, a 48-year-old religious conservative, said shortly after Supreme Court Justice Clarence Thomas administered the constitutional oath.
The US Senate
confirmed conservative jurist Amy Coney Barrett as the Supreme Court's newest justice Monday, delivering President Donald Trump
a landmark win just eight days before the election.
The deeply divided chamber voted 52 to 48, largely along party lines in the Republican-controlled Senate, making Barrett the third Trump nominee to reach the high court and cementing a six-to-three conservative majority.
Republican lawmakers broke into applause as the tally was read out, and the White House is also expected to celebrate the confirmation in the final run-up to the November 3 election, in which more than 60 million Americans have already voted.
Immediately after the vote the White House announced that Trump would attend a “swearing-in ceremony” for Barrett on the mansion's South Lawn, where she will take an oath to uphold the US Constitution.
Chief Justice John Roberts will administer the judicial oath on Tuesday at the Supreme Court, formally inaugurating her term on the bench.
