Walker will be replacing Judge Thomas Griffith who was appointed by George W. Bush.
President Trump announced on Friday that he would be nominating Justin Walker, a federal judge in Kentucky and a protégé of Supreme Court Justice Brett Kavanaugh, to a seat on the D.C. Circuit Court of Appeals, considered the second most important court in the country.
Walker, 37, was confirmed for a seat on the U.S. District Court for the Western District of Kentucky just five months ago.
He was a controversial nominee for the district court seat and was approved by committee and confirmed on the Senate floor in party-line votes. Walker was rated "not qualified" by the American Bar Association for his lack of trial experience.
After graduating from Harvard Law School, Walker clerked for Kavanaugh, then a D.C. Circuit judge, and former Supreme Court Justice Anthony Kennedy. He went on to work at two private law firms and teach part-time at the University of Louisville law school.
