WATCH: Barrett sworn in as Supreme Court justice at the White House

President Donald Trump hosted a swearing-in ceremony Monday for Amy Coney Barrett on the South Lawn of the White House, who was confirmed by a partisan Senate vote the same day.

Barrett is 48, and her lifetime appointment as the 115th justice will solidify the court’s rightward tilt.

Monday’s 52-48 vote was the closest high court confirmation ever to a presidential election, and the first in modern times with no support from the minority party. The spiking COVID-19 crisis has hung over the proceedings. Vice President Mike Pence’s office said Monday he would not preside at the Senate session unless his tie-breaking vote was needed after Democrats asked him to stay away when his aides tested positive for COVID-19. His vote was not necessary.

Justice Clarence Thomas administered the Constitutional Oath.

“This is something to be really proud of and feel good about,” Senate Majority Leader Mitch McConnell said during a rare weekend session Sunday ahead of voting. He scoffed at the “apocalyptic” warnings from critics that the judicial branch was becoming mired in partisan politics and declared that “they won’t be able to do much about this for a long time to come.”
