(CNN)Actor and musician Jussie Smollett performed at his first show since his reported attack last week, tearfully telling fans at the event in Southern California that he is not fully healed but he is doing OK. The "Empire" actor said Tuesday that he was attacked by two men who were "yelling out racial and homophobic slurs" in what Chicago police are investigating as a possible hate crime. He identifies as gay and plays a gay character on the series. Smollett said one of his attackers put a rope around his neck and poured an unknown chemical substance on him.
