Protesters hold signs during a rally to take down the Confederate flag at the South Carolina Statehouse, Tuesday, June 23, 2015, in Columbia, S.C. The shooting deaths of nine people at a black church in Charleston, S.C, have reignited calls for the Confederate flag flying on the grounds of the Statehouse in Columbia to come down. Rallies are being held, and politicians have joined the chorus of voices calling for its removal — an opinion that has carried political risks in the state in the past. (AP Photo/Rainier Ehrhardt)
