Amy Coney Barrett, fresh from a Senate confirmation vote, was sworn in Monday night as the Supreme Court’s newest justice at an outdoor ceremony at the White House.

The Senate, in a roll call that began just before 8 p.m., voted 52-48, mostly along party lines, to confirm Barrett as President Donald Trump’s third nominee to the high court.

Sen. Charles Grassley, R-Iowa, read off the vote tally, and announced: “The nomination of Amy Coney Barrett is confirmed.”

Republicans in the Senate chamber rose to their feet in applause.

Barrett, a judge on the U.S. Court of Appeals for the 7th Circuit since 2017, fills the vacancy left by the Sept. 18 death of Justice Ruth Bader Ginsburg. A conservative, she takes an originalist’s view of the Constitution in contrast to Ginsburg, a liberal icon.

Justice Clarence Thomas officiated as Barrett took the oath of office at the White House about 9:15 p.m. Thomas was a friend of the late Justice Antonin Scalia, for whom Barrett worked as a law clerk and who she considers her mentor.

“She is one of our nation’s most brilliant legal scholars. She will make an outstanding justice on the highest court in our land,” Trump said before Thomas swore in Barrett.

“The American people have been profoundly impressed to learn of her achievements, her compassion, her generosity, her faith, and her sterling character,” the president added. “Justice Barrett made clear she will issue rulings based on her faithful reading of the law and the Constitution as written, not legislation from the bench.”

After the swearing-in, Barrett spoke briefly about how the confirmation process reflected her views about the differences between the government’s legislative and judicial branches.
