WASHINGTON: Ketanji Brown Jackson was confirmed by the Senate on Thursday as the first Black woman to serve on the Supreme Court in a milestone for the United States and a victory for President Joe Biden, who made good on a campaign promise as he seeks to infuse the federal judiciary with a broader range of backgrounds.

The vote to confirm the 51-year-old federal appellate judge to a lifetime job on the nation’s top judicial body was 53-47, with three Republicans — Susan Collins, Lisa Murkowski and Mitt Romney — joining Biden’s fellow Democrats. A simple majority was needed, as Jackson overcame Republican opposition in a Supreme Court confirmation process that remains fiercely partisan.

Jackson will take the 83-year-old Breyer’s place on the liberal bloc of a court with an increasingly assertive 6-3 conservative majority. Breyer is due to serve until the court’s current term ends — usually in late June — and Jackson would be formally sworn in after that. Jackson served early in her career as a Supreme Court clerk for Breyer.

Democrat Raphael Warnock, one of the Senate’s three Black members, said in debate before the vote: “I’m the father of a young Black girl. I know how much it means for Judge Jackson to have navigated the double jeopardy of racism and sexism to now stand in the glory of this moment. ... Seeing Judge Jackson ascend to the Supreme Court reflects the promise of progress on which our democracy rests. What a great day it is in America.”

Of the 115 people who have served on the Supreme Court since its 1789 founding, all but three have been white. It has had two Black justices, both men: Clarence Thomas, appointed in 1991 and still serving, and Thurgood Marshall, who retired in 1991 and died in 1993. Current Justice Sonia Sotomayor is the only Hispanic ever to serve on it. Jackson is set to become the sixth woman justice ever.
