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."

That's a big win. Like a big big win.
