Selma

Sunday's anniversary of the day marchers were beaten by police in Selma, Ala., will honor the late civil rights icon. Some 56 years later, former state Sen. Hank Sanders says his work isn't done.

Tens of thousands marched across the Edmund Pettus bridge in the Alabama town, where 50 years ago state troopers attacked peaceful demonstrators calling for voting equality.

The president, speaking at an event in Selma, Ala., to commemorate the march, said "our union is not yet perfect. But we are getting closer."
