Trump is calling on Sweden to "Treat Americans fairly!" and "Give A$AP Rocky his FREEDOM," adding, "We do so much for Sweden but it doesn't seem to work the other way around." He's also using the popular hashtag "#FreeRocky."
Rocky, a platinum-selling, Grammy-nominated artist, has been in custody since July 3. The case has drawn the attention of a long list of U.S. celebrities, including Sean "Diddy" Combs, Justin Bieber and Kim Kardashian West.
