Biden has already elevated Judge Ketanji Brown Jackson once, appointing her last year to the U.S. Court of Appeals for the District of Columbia, which is considered the second-most powerful federal court in the country. Previously, the 51-year-old judge served on the federal district court in D.C.

California Supreme Court Justice Leondra Kruger

S. Todd Rogers

Kruger, now 45, was the youngest person to be appointed to the California Supreme Court when then-Gov. Jerry Brown nominated her in 2014.

Kruger is intimately familiar with the Supreme Court having worked as a clerk for the late Justice John Paul Stevens and served as acting deputy solicitor general in the Obama administration. While in the Solicitor General's office, she argued 12 cases in front of the Supreme Court representing the government. At the Justice Department, she also earned the Attorney General's Award for Exceptional Service, the department's highest award for employee performance, in 2013 and 2014.

At the California Supreme Court, she has authored notable opinions on the 4th Amendment — holding that law enforcement could not search a woman's purse without a warrant after she declined to provide a driver's license — and upholding a California law that requires law enforcement to collect DNA samples as well as fingerprints from all persons arrested for or convicted of felony offenses.

Though she is said to be well-liked among the alumni of the Solicitor General's office, she has not yet received the thorough vetting that other potential nominees have gone through.

South Carolina U.S. District Court Judge J. Michelle Childs

Charles Dharapak

Childs, a judge on South Carolina's federal court, is said to have a major booster in House Majority Whip James Clyburn, a Biden ally who helped deliver South Carolina for the eventual nominee in the 2020 Democratic primary. Just last month, Biden nominated Childs to the U.S. Court of Appeals for the District of Columbia Circuit, and the nomination remains pending.

A graduate of the University of South Carolina School of Law, Childs does not have the Ivy League pedigree shared by eight of the nine justices. Her cheerleaders have touted her public-school education and other elements of her background as an advantage for Democrats, according to a 2021 New York Times report, and as a way to fight back against claims that the party has become too elitist in its makeup.

In addition to a decade spent in private practice, the 55-year-old served as a state court trial judge on the South Carolina Circuit, as the deputy director of the South Carolina Department of Labor, Licensing and Regulation, and as a commissioner on the South Carolina Workers' Compensation Commission.
