Walmart CEO Doug McMillon announced in a memo to company employees on September 3 that the retail giant will discontinue sales of short-barrel rifle ammunition, as well as sales of handgun ammunition, and will end handgun sales entirely in Alaska. The announcement was made as a response to two deadly shootings at Walmart stores over the summer, one in Southhaven, Mississippi, on July 30, in which a former Walmart employee killed two people, and another in El Paso, Texas, on August 3, in which a gunman shot and killed 22 people.
