  • Cop in Rhymefest incident will be disciplined, rapper invites Trump to Chicago

The police officer who didn’t act “appropriately” when rapper Rhymefest filed a police report about an armed robbery Saturday will be disciplined, according to Mayor Rahm Emanuel. The Grammy and Oscar-winning rapper, also known as Che Smith, has been in the news after posting a video of a Chicago police officer treating him “disgustingly” when he visited the police station. “Had that officer acted appropriately, we’d be dealing right now with who did the mugging, which is where we should be,” the mayor said. Despite being robbed at gunpoint, Smith told CNN that Chicago isn’t as dangerous as Republican presidential candidate Donald Trump claims. “I’m inviting Donald Trump to Chicago,” he said in the interview with CNN. “I will walk you down a block, Mr. Trump, and I guarantee you won’t get shot.”  [DNAinfo Chicago] [CNN]
