A Chicago man accused in a terrorism case is set to change his plea to guilty in a plea deal after federal prosecutors made him an offer his attorney calls "difficult to refuse."
Shaker Masri was arrested in 2010 and charged by federal prosecutors with attempting to provide material support to a violent extremist and trying to offer material support by using a weapon of mass destruction outside the U.S.
Masri's attorney, Thomas Durkin, made the announcement outside a federal courtroom in Chicago Thursday.
Durkin declined to elaborate on the plea deal.
Masri is expected to officially change his plea July 20.
