Alabama Secretary of State John Merrill speaks during a service at Brown Chapel African Methodist Episcopal Church in Selma, Ala., Sunday, March 5, 2017. Sunday marked the 52nd anniversary of the march across the Edmund Pettus Bridge over the Alabama River in Selma. On March 7, 1965, African-Americans seeking voting rights launched a march across the bridge en route to Montgomery but were attacked by police. That violent episode became known as &#034;Bloody Sunday.&#034; (Albert Cesare/The Montgomery Advertiser via AP)
