Barrett officially becomes Supreme Court justice as John Roberts administers oath in private ceremony

Judge Amy Coney Barrett officially became Justice Barrett following a private ceremony in the Supreme Court's East Conference Room Tuesday morning.

Chief Justice John Roberts administered the Judicial Oath to Barrett, officially making her the court's 103rd Associate Justice.

"Upon administration of that oath, she will be able to begin to participate in the work of the Court," the Supreme Court said in a press release, adding that a "formal investiture ceremony will take place at a special sitting of the Court in the Courtroom at a later date."

Barrett's confirmation process took place speedily following her nomination. After the Senate Judiciary Committee held a hearing and voted Thursday to advance her nomination to the Senate floor, Senate Republicans swiftly voted Sunday to limit debate on the matter before holding a confirmation vote Monday evening.

Following a 52-48 vote, Barrett then went before Justice Clarence Thomas to take her constitutional oath at a White House ceremony.
