Wrigley, the company that makes Skittles candy, is taking issue with a controversial tweet about Syrian refugees that Donald Trump Jr. dispatched.

"Skittles are candy. Refugees are people. We don't feel it's an appropriate analogy. We will respectfully refrain from further commentary as anything we say could be misinterpreted as marketing," said Wrigley in a statement passed along Tuesday morning by Denise Young, vice president of corporate affairs for Wrigley Americas.

At issue is this tweet Monday from Trump Jr. that includes an image of a bowl of skittles and a caption reading: "If I had a bowl of skittles and I told you just three would kill you. Would you take a handful? That's our Syrian refugee problem."

"This image says it all," tweeted Trump Jr.

His father, Republican presidential nominee Donald Trump, has slammed Hillary Clinton and President Obama for allowing Syrian refugees into the country, saying that they are fueling the possibility of a terrorist attack in the United States by doing so.

The Trump Jr. tweet drew heavy criticism on social media, including from Obama's former speechwriter, who dispatched this tweet, which was heavily circulated:

Former Republican congressman Joe Walsh said he made the same point as Trump Jr. in the past.
