SALEM, Ore. (AP) — A man supported the Islamic State group for years from a Portland, Oregon, suburb by helping the extremists maintain an online presence that encouraged attacks and sought recruits, federal agents and prosecutors said. Hawazen Sameer Mothafar, who was arrested in November and whose trial is scheduled to begin in January, produced and disseminated propaganda and recruiting material through social media platforms, according to a grand jury indictment. Mothafar pleaded not guilty to charges of providing material support to a designated terrorist organization and conspiring to provide that support. Mark Ahlemeyer, his federal public defender, declined to comment.
