Ben Carson and Donald Trump. Joe Raedle/Getty Images Ben Carson took a swipe at Donald Trump on Tuesday morning after the Manhattan billionaire and his campaign spent days defending a controversial tweet.

"Social media provides a great platform for discourse, but we must be careful with the messages we send out," wrote Carson, a former 2016 presidential hopeful and current Trump surrogate.

A Carson aide later released a statement to NBC News.

"Trump has to be careful about RT any and everything," the statement read. "This would never occur from Dr. Ben Carson's account because we know that he has a platform and we must take care of that platform and be wise with the messages disseminated."

Carson's tweet came as Trump, his campaign, and fellow surrogates continue to defend a controversial tweet posted by Trump's account on Saturday.

The tweet contained an image of a six-pointed star, most commonly known as the Jewish Star of David symbol, over a pile of money. The star was inscribed with the words "most corrupt candidate ever" and appeared next to an image of presumptive Democratic nominee Hillary Clinton.

The image, which was posted to a white-supremacist message board days before being posted on Twitter by the Trump campaign, has ignited controversy.

Trump and his campaign called the shape a "sheriff's star" and a "plain star," although the tweet was soon deleted and replaced with a similar image that instead included a circle.
