Judge Ketanji Brown Jackson, the first Black woman nominated to the U.S. Supreme Court, faces four days of high-profile confirmation hearings before the Senate Judiciary Committee.  Today's session kicked off with up to 10-minute opening statements from Senate Judiciary Committee members, five-minute statements from outside introducers, and then 10 minutes from Jackson herself.  While Democrats have the votes to confirm President Biden's first Supreme Court nominee on their own, and hope to by the middle of April, the hearings could prove critical to the White House goal of securing at least some Republican support and shoring up the court's credibility.
