Like President Trump, Justin Bieber would like to see rapper A$AP Rocky released by Sweden. But Trump's intervention reminded Bieber of another issue, Vanity Fair reports. While you're at it, Bieber tweeted, "Can you also let those kids out of cages?" The rapper is in Swedish custody over a street fight, and Bieber has supported a petition calling for his release. "I want my friend out," he confirmed in his tweet Saturday, saying that he appreciated Trump's help. But migrant children are still being held in detention centers near the Mexican border, per CNN. Trump did not immediately answer Bieber's tweet. (More Justin Bieber stories.)
