MINNEAPOLIS (AP) — Closing arguments are scheduled to begin Tuesday in the trial of three Minnesota men accused of plotting to travel to Syria to join the Islamic State group.

Twenty-two-year-old Abdirahman Yasin Daud, 22-year-old Mohamed Abdihamid Farah and 21-year-old Guled Ali Omar have pleaded not guilty to multiple counts, including conspiracy to commit murder outside the United States, which carries a possible life sentence.

Prosecutors spent more than two weeks presenting evidence that they say shows the men were part of a larger group of friends who conspired to travel to Syria. Evidence included recordings made by an FBI informant.

Omar testified in his defense. He said he had doubts about the plan and was showing off when he made statements that were caught on tape. Daud and Farah did not testify.
