By the middle of the decade, open condemnation of the war became more common, with figures like Malcolm X and Bob Moses speaking out. Champion boxer Muhammad Ali risked his career and a prison sentence to resist the draft in 1966. Soon Martin Luther King Jr., Coretta Scott King and James Bevel of the Southern Christian Leadership Conference (SCLC) became prominent opponents of the Vietnam War, and Bevel became the director of the National Mobilization Committee to End the War in Vietnam. The Black Panther Party vehemently opposed U.S. involvement in Vietnam. In the beginning of the war, some African Americans did not want to join the war opposition movement because of loyalty to President Johnson for pushing Civil Rights legislation, but soon the escalating violence of the war and the perceived social injustice of the draft propelled involvement in antiwar groups.
