President Biden has chosen Ketanji Brown Jackson as his Supreme Court nominee, according to a White House announcement on Friday morning. If confirmed, she will become the first African-American woman to serve on the United States Supreme Court.

Jackson, 51, was nominated to the United States Court of Appeals for the District of Columbia by Biden last summer. Jackson formerly served as a public defender, vice-chair of the United States Sentencing Commission, and clerk to retiring Supreme Court Justice Stephen Breyer before being appointed to the United States District Court for the District of Columbia in 2013. If confirmed, Jackson would become the Supreme Court’s first federal public defender.

The White House issued a statement saying, “Judge Jackson is an exceptionally qualified nominee as well as an historic nominee, and the Senate should move forward with a fair and timely hearing and confirmation.”

On Friday afternoon, both Biden and Jackson will deliver speeches.
