Following Clay's upset victory over Liston, both fighters were almost immediately embroiled in controversy that was considered detrimental to the sport of boxing. A couple of days after the fight, Clay publicly announced that he had joined the "Black Muslims"—which was widely viewed as a hate group against white people—and started going by the name Cassius X. The following month, he was renamed Muhammad Ali by Nation of Islam leader Elijah Muhammad. This evoked widespread public condemnation. Martin Luther King Jr. said, "When Cassius Clay joined the Black Muslims and started calling himself Cassius X, he became a champion of racial segregation." As for Liston, he was arrested on March 12 and charged with speeding, careless and reckless driving, driving without an operator's license and carrying a concealed weapon. The arresting officer said the former champion was driving between 76 and 80 mph (122–128 kmh) in a residential zone. Liston had a loaded .22 caliber revolver in his coat pocket and there were empty bottles of vodka in the car. A young woman was in the car with Liston, but she was not arrested. In short, at a time when Congress was investigating corruption and organized crime influence in boxing, neither fighter was seen as a poster child for the sport.
