President Trump said Thursday that the FBI and the Justice Department will probe Chicago prosecutors’ handling of the Jussie Smollett case.

“FBI & DOJ to review the outrageous Jussie Smollett case in Chicago. It is an embarrassment to our Nation!” the president tweeted.

His tweet came several hours after a report by Chicago’s WLS-TV, citing law enforcement sources, that the FBI launched a probe of Windy City prosecutors’ secret deal to drop the 16-count indictment against the “Empire” actor.

On Wednesday, State’s Attorney Kim Foxx defended the bombshell decision to walk away from the prosecution — even as she maintained her office had an airtight case.

“Based on the facts and the evidence … this office believes that they could prove him guilty,” Foxx told WLS.

But she added of prosecutors’ decision to let Smollett walk free with no more than the forfeiture of his $10,000 bail and 16 hours of community service, “I believe this is a just outcome based on the circumstances.”
