A voting registration campaign in 1965 turned tragic on February 17 when an Alabama state trooper fatally shot Jimmie Lee Jackson in Marion, prompting a protest march from Selma to Montgomery that became a milestone in the Civil Rights Movement. On March 7, John Lewis and Hosea Williams led 600 African Americans from Brown Chapel AME Church across the Edmund Pettus Bridge, where State Public Service Director Al Lingo ordered armed troopers to attack them, hospitalizing 50. Two weeks later, Rev. Martin Luther King Jr. and Rev. Ralph Abernathy led a court-approved march with federal protection that covered 54 miles and reached the State Capitol on March 25, where King spoke before 25,000. Racists killed Boston minister James Reeb on March 11 and Detroit housewife Viola Gregg Liuzzo on March 25. Television coverage of Bloody Sunday shocked millions and galvanized support for Congress to remove obstacles that prevented minorities from voting, and President Lyndon Johnson signed the Voting Rights Act of 1965 on August 6. As a result, many blacks won local elections in the South. In 2007, a bridge crossing reenactment attracted presidential candidates Hillary Clinton and Barack Obama, and after Obama won the Democratic nomination the following year, he spoke of the bridge in Selma in his acceptance speech. In 2009, nearly two million witnessed the inauguration of America's first black president. Shortly before the fiftieth anniversary of Bloody Sunday, Selma, the Oprah Winfrey and Ava DuVernay film about voting rights, was nominated for the Best Picture Academy Award.
