In September 1962, James Meredith enrolled at the University of Mississippi but was prevented from entering. Attorney General Robert Kennedy responded by sending 400 federal marshals, while President Kennedy reluctantly sent 3,000 troops after the situation on campus turned violent. The Ole Miss riot of 1962 left two dead and dozens injured, but Meredith did finally enroll in his first class. Kennedy regretted not sending in troops earlier and he began to doubt whether the "evils of Reconstruction" he had been taught or believed were true. On November 20, 1962, Kennedy signed Executive Order 11063, prohibiting racial discrimination in federally supported housing or "related facilities".
