I've found it curious how wingnuts kept saying the Governor has to act before National Guard troops can be sent in. If so, then is this correct about the Arkansas integration efforts?
U.S. Congressman Brooks Hays and Little Rock Mayor Woodrow Mann asked the federal government for help, first in the form of U.S. marshals. Finally, on September 24, Mann sent a telegram to President Eisenhower requesting troops. They were dispatched that day and the President also federalized the entire Arkansas National Guard, taking it away from the Governor.
Note the article says the troops were federalized OVER the objection of the governor.
