Walmart will require all customers to wear masks

• The company notes that 65% of its stores are located in areas where "there is some form of government mandate on face coverings."
• Walmart says the mandate is meant to "help bring consistency across stores and clubs."

Walmart also said it would have "Health Ambassadors" stationed near the entrances of stores to remind customers without masks of the new requirements.

What they're saying: "We know some people have differing opinions on this topic. We also recognize the role we can play to help protect the health and well-being of the communities we serve by following the evolving guidance of health officials like the CDC," the company wrote in a press release.

• "We appreciate the understanding and cooperation of our customers and members in wearing face coverings to protect their safety and the safety of our associates."

Editor's note: This story has been corrected to reflect that Walmart has over 5,000 stores in the U.S., not 9,000.
