Police in Chicago say a person is in custody in an investigation of a large cross set on fire in a well-known park. The burning cross was discovered June 9 in Grant Park. That's the same park where Barack Obama delivered his acceptance speech when he was elected the nation’s first Black president in 2008. A 21-year-old college student told WMAQ-TV that he was protesting President Donald Trump and not making a racist statement. It's not clear if that same man is the person under arrest. Cross burnings in the U.S. have historically been seen as symbols of hate against Black people.
