In October 1943 Prince Faisal and Prince Khalid visited the United States representing their father, upon the July 1943 invitation of President Franklin D. Roosevelt. The visit was the earliest high-level contact between Saudi Arabia and the USA. Vice President Henry A. Wallace organized a dinner for them at the White House. They also met with Roosevelt. They stayed at the official government guest house, Blair House, and visited the West Coast by a special train that was officially provided by the US government. A foreign diplomat described Prince Khalid following the visit as the "nicest man in Saudi Arabia."
