President Donald Trump’s demand that Coca-Cola return to using cane sugar in its iconic drink appears to have hit a major snag.

The Coca-Cola Co. said Tuesday its third quarter revenue rose largely due to higher prices. The Atlanta beverage giant said Tuesday that its organic revenue grew 6% to $12.41 billion in the July-September period.
