Today is the 50th anniversary of the landmark Voting Rights Act, passed Aug, 6, 1965. The act, signed into law by President Lyndon B. Johnson, created key provisions to prevent racial discrimination in voting laws.
The Voting Rights Act has been called "the single most effective piece of civil rights legislation ever passed by Congress."
Today's anniversary is a bittersweet commemoration. In 2013, the Supreme Court struck down Section 4, which had required Alabama, Alaska, Arizona, Georgia, Louisiana, Mississippi, South Carolina, Texas, and Virginia to seek federal approval before imposing changes to voter laws.
