NBC — The trial of the man accused of trying to set off a car bomb at a Portland holiday ceremony begins this week.
Twenty-one year-old Mohamed Mohamud is accused of attempting to detonate a weapon of mass destruction.
Prosecutors say he intended to set off an 1,800 lb. car bomb at a Portland christmas tree lighting ceremony in 2010.
The bomb was a fake provided by the FBI.
Prosecutors say the Somali-born Mohamud was highly motivated to carry out violent jihad.
