After his time as the Attorney General of Nebraska, he became an important counsel for the
Union Pacific Railroad Company. In this capacity he represented the Union Pacific in many legal cases before courts such as the U.S. District Court for the Southern District of Iowa and the US Court of Appeals for the Seventh Circuit among others. As a counsel for the Union Pacific, he was called on to represent the company before the
United States Supreme Court as well. In one such case,
United States v. Union Pacific R. Co. – argued from January 23, 1957 and decided on April 8, 1957 – he had on his legal team,
Warren M. Christopher, who would later serve as US Secretary of State. Representing the United States as opposing counsel was U.S. Solicitor General
James Lee Rankin, along with a team of lawyers that assisted him. Six years later James Rankin would be appointed General Counsel on the
Warren Commission. ==References==
