Walmart — the world's largest retailer — is now issuing a warning to customers that they may be paying more for the same products if President-elect Donald Trump makes good on his promise to impose new tariffs on imports.

Walmart CFO John David Rainey told FOX Business that the company won't be immune if President-elect Trump pursues a tariff on imports from all foreign countries.

Our model is everyday low prices,” CFO John David Rainey said. “But there probably will be cases where prices will go up for consumers.”
