Vermont Sen. Bernie Sanders' recent accusation that Hillary Clinton "shouts" when she discusses guns was entirely unrelated to her gender, Sanders told CNN on Sunday.

During a campaign speech Friday in Alexandria, Va., the former secretary of state told supporters she'd "been told to stop shouting about guns," in a clear reference to Sanders.

"Actually, I haven't been shouting, but sometimes when a woman talks, some people think it's shouting," Clinton said.

"She's basically calling you a sexist," CNN's Jake Tapper told Sanders on Sunday. "She is suggesting, in public, that you have a problem with women speaking out."
