Thousands of people marched down the Edmund Pettus Bridge in Selma, Alabama Sunday.
WIAT reported "An impromptu set of leaders formed the lines, and then they led the march across the Edmund Pettus Bridge."
The march commemorated the 50th anniversary of "Bloody Sunday," when about 600 peaceful civil rights protesters were attacked by Alabama police.
The ceremony began with a service at Selma's famous Brown Chapel AME, the starting place of the Selma to Montgomery marches in 1965.
The Voting Rights Act, which was gutted in a 2013 Supreme Court decision, was a major topic of discussion. At the chapel, Eric Holder said "We will march on until every citizen is afforded his or her fundamental right to vote."
Rev. Jesse Jackson said, "There is a radical resegregation taking place in our society today."
Martin Luther King III added, "I'm concerned, because our voting rights have been decimated."
And President Obama said, "The Voting Rights Act stands weakened. ... How can that be?"
One day earlier, President Obama marched across the bridge alongside civil rights icons and over 100 members of Congress.
Sunday's march drew an estimated 80,000 people total — a crowd so large the march had to be briefly postponed. (Video via NBC)
