President Donald Trump nominated Judge Neil Gorsuch to the U.S. Supreme Court on Tuesday night, saying in a speech at the White House: “This may be the most transparent judicial process in history.” Gorsuch, 49, sits on the U.S. Court of Appeals for the 10th Circuit and is the youngest Supreme Court nominee in 25 years. Gorsuch has a Ph.D. from Oxford University, where he was a Marshall Scholar, and was nominated to the federal bench by President George W. Bush in 2006. He is an “originalist” conservative in the tradition of Supreme Court Justice Antonin Scalia, who died in 2016. During his speech Tuesday, Gorsuch referred to Scalia as a “lion of the law.”
