He announced his choice in a call Thursday evening, another person familiar with the process said, extending the offer on the eve of the announcement. He makes calls to the two remaining finalists on Friday morning.

Ketanji Brown Jackson, 51, who currently serves on the United States Court of Appeals for the District of Columbia, is considered the frontrunner.

Biden is set to make the announcement on Friday afternoon. A ceremony on Friday would mark two years to the day when Biden made his initial promise to choose the first African-American female judge in a 2020 primary debate in South Carolina.

Vice President Kamala Harris postponed a trip to Louisiana scheduled for Friday, suggesting an announcement was forthcoming. And White House press secretary Jen Psaki told reporters on Wednesday that there were no circumstances under which Biden would hold his announcement after February, suggesting the crisis in Ukraine has not derailed their objective.

Multiple sources told CNN that Biden has met with at least three potential candidates. These women are Jackson; Leondra Kruger, who sits on the Supreme Court of California; and J. Michelle Childs, who sits in the United States District Court for the District of South Carolina.
Earlier Thursday, a federal court increased the buzz surrounding Jackson as a potential candidate.

The United States Court of Appeals for the DC Circuit deviated from its usual procedure by issuing an opinion on a Thursday – breaking with its usual schedule of Tuesday and Friday as release days. Notably, Jackson was in the majority in the 2-1 decision on the case.

Some legal experts took the release as a sign that Jackson could be the nominee and the announcement could come as soon as Friday, particularly because a similar scenario had unfolded with current judge Brett Kavanaugh.

Jackson was elevated to the DC Circuit last year by Biden, after serving nearly a decade on DC’s federal district court. She has long been considered the favorite to replace retired judge Stephen Breyer, for whom she served as clerk. His experience working as a DC public defender has been touted by his supporters — as Biden has sought to bench more public defenders.

Although Biden’s choice won’t change the balance of the court, the new nominee is likely to serve for decades. The court currently has six conservative judges appointed by Republican presidents and three liberal judges appointed by Democrats.
