CHICAGO -- Chicago's top cop is responding to claims by Donald Trump that police could end the city's violence "in one week" if they want to.
“If you have a magic bullet to stop the violence anywhere, not just in Chicago but in America, then please, share it with us," Chicago Police Supt. Eddie Johnson said Sunday.
Last week, Trump claimed that he spoke with a high-ranking officer in Chicago about the violence in the city, but the police department says that's not true.
Trump then tweeted about Nykea Aldridge's murder on Saturday, saying African Americans will vote for him. Aldridge is the cousin of Chicago Bulls player Dwyane Wade.
However, that tweet backfired and he was criticized on social media.
He later tweeted his condolences to Wade and his family.
A pair of brothers have been charged in Aldridge's murder.
