Wednesday, the Senate Judiciary Committee completed its third day of hearings on the nomination of federal appellate judge Ketanji Brown Jackson to the Supreme Court. Lets’ be clear: Judge Jackson’s credentials are impeccable. She is the only Supreme Court nominee ever to have served as a public defender. She has handled civil and criminal cases, served on the federal sentencing commission, worked in private law firms and clerked for Stephen Breyer (the justice she’d be replacing).
