Outspoken rapper and activist Sister Souljah unexpectedly became the focus of the 1992 presidential campaign. After the L.A. riots, she said, "If Black people kill Black people every day, why not have a week and kill white people?" prompting candidate Bill Clinton to repudiate her in a famous speech. Even today, when a politician distances themselves from an extremist person, group or opinion, it's often called a "Sister Souljah moment."
