The building of the Mansion was actually commissioned in 1947, and the mansion became operational in 1950. Prior to this, there was no official governor's residence in Arkansas.
With the destruction of Washington, DC by the Race's explosive-metal bomb in 1942, the capital of the United States moved to Little Rock, Arkansas, and the Arkansas Governor's Mansion became the official residence of the President. It was rechristened the Gray House by the press, in honor of the former White House.
Sam Yeager met with President Earl Warren in the Gray House on two occasions between 1963 and 1964. Warren committed suicide there in 1965. His successor Harold Stassen summoned Yeager back to the Gray House to discuss new developments.
