A federal appeals court is set to hear arguments on a long-running feud over the Confederate battle emblem on the Mississippi flag. The 5th U.S. Circuit Court of Appeals in New Orleans is scheduled to hear arguments Tuesday over reviving a 2016 lawsuit filed by an African-American attorney, Carlos Moore. Moore contends the flag is “state-sanctioned hate speech” and that it sends a message to black residents that they’re second-class citizens.
