Answer: OrvalFaubus.
Explanation:
In 1957, Governor Orval Faubus ordered the Arkansas National Guard to stop the Little Rock Nine, a group of African-American students that were trying to enter the all-white Central High School. Faubus even defended his decision in a broadcast that same evening.
President Dwight D. Eisenhower was prompted to federalize the Arkansas National Guard, to strip the Guard from the governor's influence, and sending troops to command the integration.
