"The Mexican-born Castro was governor of Arizona from 1974 to 1977. He was the state’s first and only Hispanic governor. He and his wife retired to Nogales after he served as U.S. ambassador to Argentina. He also served as ambassador to Bolivia and El Salvador in the 1960s. In an interview, Castro told The Republic that he was “not thrilled” by the way he was treated but did not file a complaint. He said that he understands Border Patrol agents are “there to do a job” but that they need a better system for dealing with elderly people. He said he was exposed to the sun during part of the questioning. “The sun was blazing on me,” he said. “Once I identified myself, who I was, and that I had been to the doctor, I was under medical care, I have a pacemaker on my heart, (I would have thought) that they would have been more considerate and said, ‘Keep on going.’ But that didn’t happen,” Castro said."
