Jussie Smollett

Cook County prosecutors' decision to dismiss all charges against the "Empire" actor continues to stoke controversy. 

Federal investigators are reportedly working with the U.S. Postal Service to figure out whether Jussie Smollett had a hand in sending the racist letter he received prior to the alleged hate crime, meaning the actor could still face charges.

Prosecutors had alleged the "Empire" star lied about being the victim of a racist and homophobic attack.

The "Empire" actor has been charged with 16 counts of disorderly conduct for allegedly lying to police about being the victim of a racist, homophobic assault.

Olabinjo and Abimbola Osundairo “put their trust in the wrong person,” attorney Gloria Schmidt said.

Smollett's attorney Mark Geragos Calls calls the 16 felony counts against the "Empire" actor outrageous and criticizes police for "false" leaks to the media.

“Jussie Smollett knew that at the time … there was no reasonable ground for believing that such offenses had been committed,” the indictment said.

“I’ll be completely honest, I was like 'I don’t know if I want to do the interview or not,'” the news anchor  said of her high-profile sit down with Smollett.

Olabinjo and Abimbola Osundairo’s attorney said in a statement that the two are aware of the impact the case has had, and are sorry for their part..

The $3,500 check is written to Abimbola Osundario, one of two brothers Smollett allegedly hired for the attack, and says in its memo line it’s for a “nutritional/workout program.”
