Story highlights Walmart is under pressure to stop selling guns after the Charleston massacre

Walmart CEO: "Our focus as it relates to firearms should be hunters"

(CNN) Confederate flags are off the shelves at Walmart. But still up for grabs: guns.

Walmart, the nation's largest retailer, was the first to announce plans this week to remove Confederate flag products from its stores after Dylann Roof killed nine African-Americans in a Charleston, South Carolina church. The company was hailed by many for quickly responding to the uproar over the flag. But it has since come under pressure to also stop selling guns in response to the nation's latest mass shooting.

"I would hope that stores like Walmart would recognize the danger of having these guns displayed right next to an aisle away from microwave popcorn and and Xbox games," said U.S. Sen. Chris Murphy, a Connecticut Democrat who has pressed for gun control since 20 children were shot and killed at a school in his state in 2012. "I'm not terribly confident that a 21-year-old Walmart clerk is going to sell guns responsibly or be able to give customers the kind of advice they need on how to responsibly use that gun."

The debate over the Confederate flag has also raised broader questions about where the line should be drawn for retailers that sell other questionable or offensive products.
