The memo follows a statement from Walmart CEO Doug McMillon earlier in the week in which he vowed a "thoughtful and deliberate" response to the shootings.
"We will work to understand the many important issues that arise from El Paso and Southaven, as well as those that have been raised in the broader national discussion around gun violence," McMillon said in a memo to employees.
Although some public officials, including President Donald Trump, have pointed to violent video games as a cause of the rise in gun violence, numerous studies have found no link between the games and actual violent behavior.
Many people have called on Walmart to stop selling guns altogether. Some Walmart employees have voiced their concerns about the store's gun sales.
Walmart does not sell assault style rifles, nor does it sell handguns outside of Alaska. It also does not sell any weapons to customers younger than 21. Walmart stopped selling assault rifles after the Sandy Hook shooting in 2015, and it changed its age policy followed the shooting at a high school in Parkland, Florida, last year.
