Finding that federal anti-discrimination laws, particularly the Civil Rights Act of 1964, are not sufficient to overcome the resistance by state officials to enforce the 15th Amendment (as soon as one discriminatory practice is struck down, states impose a new one), Congress adopts this comprehensive voting rights law. The legislation, which President Lyndon Johnson signs into law on Aug. 6, 1965, temporarily suspends literacy tests and provides for the appointment of federal examiners (with the power to register qualified citizens to vote) in voting districts across the nation. Under this law, any racially discriminatory act that prevents Americans from voting is prohibited. After its passage, the voting rate for African Americans will increase rapidly.
