Ketanji Brown Jackson, a former public defender and Supreme Court clerk, was nominated Thursday by President Obama for a seat on the District’s federal court.

Jackson, 42, has served since 2010 as vice chair and commissioner of the U.S. Sentencing Commission, an agency within the judiciary that sets sentencing policies and practices. The Harvard Law School graduate served as an assistant federal public defender from 2005 through 2007 and later worked at the firm of Morrison & Forester. She was a law clerk for Supreme Court Justice Stephen G. Breyer.

Jackson would be the first black woman appointed to the District’s federal court in 32 years. If confirmed, she would be only the second to serve on the bench.

“I could not be more pleased that the President has agreed to nominate Ketanji Brown Jackson to our federal district court,” said Del. Eleanor Holmes Norton (D) in a statement. “Her experience in both civil and criminal matters, including sentencing, will make her a valuable addition to the court.”
