CHICAGO (AP) — A 19-year-old suburban Chicago man facing a terrorist charge for allegedly trying to join Islamic State group militants in Syria will have his chance to enter a plea.

Mohammed Hamzah Khan’s arraignment Tuesday at federal court in Chicago comes days after a grand jury indicted him on a count of attempting to provide material support to a foreign terrorist organization.

Khan lived with his parents in Bolingbrook. He’s been in custody since his October arrest at O’Hare International Airport.

Khan was charged in a criminal complaint in October. The indictment returned last week formalizes that charge. A conviction carries a maximum 15-year prison sentence.

Khan’s attorney says his client appeared to have fallen under the influence of Islamic State propaganda. But he has also described the government’s case as weak.
