On June 11, Malone and Hood arrived to register. Wallace, attempting to uphold his promise as well as for political show,[4] blocked the entrance to Foster Auditorium with the media watching. Then, flanked by federal marshals, Deputy Attorney General Nicholas Katzenbach told Wallace to step aside.[5][1] However, Wallace cut Katzenbach off and refused, giving a speech on States' rights.[4] Katzenbach called President John F. Kennedy, who federalized the Alabama National Guard. General Henry Graham then commanded Wallace to step aside, saying, "Sir, it is my sad duty to ask you to step aside under the orders of the President of the United States." Wallace then spoke further, but eventually moved, and Malone and Hood registered as students.[6]
