After presiding over the Senate chamber the historic vote, Vice President Kamala Harris told reporters she is "overjoyed and deeply moved" at Judge Jackson's successful confirmation to the Supreme Court.

"There’s so much about what’s happening in the world now that is presenting some of the worst of this moment and human behaviors -- and then we have a moment like this that, I think, reminds us that there is still so much yet to accomplish and that we can accomplish," she said.

Harris said Jackson's ascension sends an "important statement about who we are as a nation -- that we have just made a decision to put this extraordinary jurist on the highest court of our land."

"So let us all I think -- with rejoice -- in who we are as a nation that we achieved -- long overdue -- but we achieved this important milestone," she said. "It makes a very important statement about who we aspire to be, who we are, who we believe ourselves to be."

Harris said is a statement that says "we want to make sure there is going to be full representation -- and the finest and brightest and the best -- and that’s what happened today," she said. "I’m very proud. Very proud."

With Judge Jackson now Senate-confirmed to the Supreme Court, the White House has announced it will hold an event on the South Lawn on Friday afternoon to celebrate her confirmation.

President Joe Biden, Vice President Harris and Judge Jackson will speak, according to the White House.

The White House has framed Jackson's confirmation as a fulfillment of two big Biden promises -- one from the campaign trail, that he'd nominate the first Black woman, and the other as president, that he'd nominate someone in the mold of retiring Justice Stephen Breyer.

Jackson joined Biden in the Roosevelt Room on Thursday afternoon to watch the results of the Senate roll call vote -- ending with bipartisan confirmation to sit on the high bench.

With Judge Jackson set to become Justice Jackson when Justice Stephen Breyer retires at the end of this term, the Supreme Court will have its first Black woman justice -- and Jackson will serve on the first-ever high court where white men constitute a minority of the membership.

Jackson is also the first former public defender and first Florida-raised judge to sit on the Supreme Court.

In addition to being the first time four women justices serve on the bench, it’s also the first time three justices of color will serve together.

Biden ran for president on the pledge to nominate a Black woman and to help make the courts “look more like America.”
