According to a police statement, the actor was walking near the Chicago River downtown around 2 a.m. Tuesday when he was approached by two men who shouted at him, struck him in the face and poured an "unknown substance" on him before one of them wrapped a rope around his neck.
Police spokesman Anthony Guglielmi said that when officers first came in contact with Smollett, he still had a rope around his neck. While being interviewed by detectives, Guglielmi said Smollett told them that the attackers yelled he was in "MAGA country," an apparent reference to the Trump campaign's "Make America Great Again" slogan that some critics of the president have decried as racist and discriminatory.
The police spokesman added that the two men were wearing masks. Investigators have not found any surveillance video or witnesses from which they can put together a description of the offenders, he said.
Smollett was able to take himself to Northwestern Memorial Hospital. He was last reported in good condition. Guglielmi also said the FBI is investigating a threatening letter targeting Smollett that was sent to the Fox studio in Chicago last week.
The hourlong drama "Empire" follows an African-American family as they navigate the ups and downs of the record industry. Jamal Lyon, Smollett's character, is the gay, middle son of Empire Entertainment founder Lucious Lyon and Cookie Lyon, played by Terrence Howard and Taraji P. Henson, respectively.
Twentieth Century Fox Television and Fox Entertainment released a statement Tuesday in support of Smollett. "The entire studio, network and production stands united in the face of any despicable act of violence," the statement read.
"Empire" co-creator Lee Daniels also voiced his support for Smollett in an Instagram video. "You didn't deserve, nor anybody deserves, to have a noose put around your neck," Daniels said. "You are better than that, we are better than that, America is better than that."
California Sen. Kamala Harris, a 2020 Democratic presidential hopeful, knows Smollett personally and called the attack "outrageous" and "awful." "He is one of the kindest, most gentle human beings I've ever met," Harris said Tuesday, adding that she's still learning more details about the incident.
Smollett has been active in LBGTQ issues and he released his debut album, "Sum of My Music," last year. "Empire" is shot in Chicago and a Fox spokeswoman said the program is currently in production.
