Chicago’s police union has demanded an investigation into Cook County State’s Attorney Kim Foxx her text messages with Jussie Smollett’s family friends.

Before recusing herself from the case in mid-February, Foxx exchanged texts with Michelle Obama’s former chief of staff, Tina Tchen, a close friend of the Smollett family.

Tchen, 63, sent a text to Foxx three days after Smollett, an actor on television's "Empire," claimed he was the victim of a hate crime, saying that she wanted to set up a phone call to discuss the case.

“I wanted to give you a call on behalf of Jussie Smollett and family who I know. They have concerns about the investigation,” Tchen said in a text sent Feb. 3 before 5 a.m.

On Tuesday, the Fraternal Order of Police called for an investigation into Foxx’s “interference” in Smollett’s case after Illinois state prosecutors announced they were dropping all 16 felony charges brought against Smollett for allegedly staging the attack against him.

Patricia Brown Holmes, Smollett’s attorney, insists he did not receive special treatment. "There was no political influence in this case," she said, adding that she believes city officials are upset because they didn’t know prosecutors were going to drop the case.

Smollett, who is gay and black, claimed that he was attacked by two men yelling racist and homophobic slurs while beating him, throwing bleach at him, and putting a rope around his neck. Weeks later, he was charged with disorderly conduct and filing a false police report after investigators said he paid the two men to stage the attack in the hopes of raising his profile enough to boost his "Empire" salary.
