The Cook County State's Attorney's office says Sen. Donne Trotter is scheduled to appear in bond court on Thursday morning. Trotter was arrested Wednesday at Chicago's O'Hare International Airport, where a transportation security officer discovered the firearm in a garment bag during an X-ray screening.
Police say he was carrying an unloaded .25-caliber Beretta handgun and a magazine clip with ammunition.
The 62-year-old told Transportation Security Administration officers he uses the weapon for work as a security officer.
The Chicago Democrat recently announced plans to run for Jackson's U.S. House seat.
