The confirmation shattered a historic barrier by securing her place as the first Black female justice and giving President Joe Biden a bipartisan endorsement for his effort to diversify the high court.

Cheers rang out in the Senate chamber as Jackson, a 51 year-old appeals court judge with nine years experience on the federal bench, was confirmed 53-47, mostly along party lines but with three Republican votes. Presiding and emotionally announcing the vote was Vice President Kamala Harris, also the first Black woman to reach her high office.

“This is a tremendously historic day in the White House and in the country,” said White House press secretary Jen Psaki after the vote. “And this is a fulfillment of a promise the president made to the country.”

Jackson will take her seat when Justice Stephen Breyer retires this summer, solidifying the liberal wing of the 6-3 conservative-dominated court. She joined Biden at the White House to watch the vote, embracing as it came in.
