>> that was a sneak peek of the documentary film "city of ali" which premiered earlier in his hometown, louisville, kentucky. he was one of the greatest athletes of all time, but he was also a world-renowned humanitarian and civil rights activist. the documentary follows ali's life and the events after his death in 2016 due to parkinson's disease. over 100,000 people joined his funeral procession in louisville. joining me now is the daughter of muhammad ali, and her son, jacob ali worth heimer, grandson of muhammad ali, both human and civil rights activists in their own right. thank you both for being with us. let me start with you, kalila.
