President Donald Trump plans to nominate Amy Coney Barrett to the Supreme Court on Saturday. The judge is a favorite of social conservatives who, if confirmed, will be the youngest justice on the court and could reshape the nations laws for decades.

CNN , CBS and PBS reported Barrett as Trumps pick on Friday. Barrett was widely seen as the front-runner to fill the seat that opened when Justice Ruth Bader Ginsburg died on Sept. 18, and she was on the short list to replace Justice Anthony Kennedy in 2018. That seat ultimately went to now-Justice Brett Kavanaugh.

Barrett, 48, has been a judge on the U.S. Court of Appeals for the 7th Circuit since 2017. She taught for 15 years at Notre Dame Law School in Indiana, and before that, clerked for the late Supreme Court Justice Antonin Scalia.

Civil and human rights groups strongly opposed Barretts nomination to her current court seat over her views on a range of issues.
