The scrutiny over Coke’s sweeteners began Wednesday, when President Donald Trump announced that Atlanta-based Coca-Cola Co. had agreed to switch to using cane sugar in the regular version of its beverage manufactured in the U.S.

Asked about the switch, a representative for Coca-Cola didn’t explicitly say it would use cane sugar for products in the U.S.

President Donald Trump announced Wednesday that Coca-Cola would switch from using high-fructose corn syrup to real cane sugar in its drinks. The president made his announcement on Truth Social, but people online were skeptical that Trump was telling the truth, and with good reason. Trump lies constantly.
