The U.S. Senate confirmed Jackson in a 53-47 vote in April, with three Republicans joining 50 Democrats and independents in supporting Biden's nomination of her for the Supreme Court.
The Supreme Court is the final appellate court of the U.S. judicial system, with the power to review and overturn lower court decisions, and is also generally the final interpreter of federal law, including the country's constitution.
Since the Supreme Court was established in the United States in 1789, 116 justices have been confirmed to the bench. Of them, 108 are white men and only six are women, including Jackson. The justices have life tenure and can serve until they die, resign, retire, or are impeached and removed from office.
Born in Washington, D.C. but raised in Miami, Florida, Jackson received her law degree from Harvard University and graduated cum laude in 1996. Earlier in her legal career, she worked as an assistant federal public defender in D.C. and served as vice-chair of the U.S. Sentencing Commission for four years.
Jackson served more than eight years as a judge on the U.S. District Court for the District of Columbia before being elevated to the U.S. Court of Appeals for the D.C. Circuit in June 2021.
Court watchers believe Jackson is expected to vote very similarly to Breyer and her ascension won't change the Supreme Court's ideological balance, in which conservatives have a 6-3 majority over liberals.
