Mississippi Republican Sen. Roger Wicker said on Wednesday that his state's flag, which features a Confederate battle emblem in its upper left corner, should be replaced with one that is more unifying.

Weighing in on a debate that has swept across the American South since the massacre of nine blacks in a South Carolina church last week, allegedly by a white gunman, Wicker said Mississippi's flag should be put in a museum and replaced.

"As the descendant of several brave Americans who fought for the Confederacy, I have not viewed Mississippi's current state flag as offensive," Wicker said in a statement.
