President Obama has nominated a sentencing expert to the District’s federal bench and selected a prosecutor to serve as a D.C. Superior Court judge, the White House said Thursday.

Obama picked Ketanji Brown Jackson for a U.S. District Court judgeship. Jackson has been a member of the U.S. Sentencing Commission since 2010, and she’s currently the panel’s vice chairwoman. She previously worked as a federal public defender in D.C., served as a clerk to U.S. Supreme Court Justice Stephen Breyer and worked in private practice.
