Trump vowed last week that he would nominate a woman for the vacancy within a week, saying he had an “obligation” to act without delay.

Standing next to Barrett in the White House Rose Garden on Saturday, Trump called the judge "eminently qualified" for the job. He said she will decide cases "based on the text of the constitution, as written."

Taking to the podium after Trump, Barrett said she was "truly humbled" by the prospect of serving on the Supreme Court. She also paid tribute to the late Justice Ginsburg.

Barrett, 48, currently serves on the 7th US Circuit Court of Appeals in Chicago. If confirmed, she'll be the only Supreme Court justice who didn't attend Harvard or Yale University — and the first who didn't get an Ivy League law degree since the late John Paul Stevens was nominated in 1975. Barrett, a New Orleans native, attended Notre Dame University, where she graduated first in her class in 1997.

Her Catholic faith was questioned by Democrat Senators when Barrett was appointed by Trump to the 7th US Circuit Court in 2017. Senator Dianne Feinstein questioned would have unbiased legal opinions, given that "the dogma lives loudly within you." Senator Dick Durbin asked Barrett whether she considers herself an "orthodox Catholic."
