A federal grand jury indicted 30 year old Mufi Elfgeeh on seven counts after he tried to help three people travel to Syria to fight for Islamic State.
Elfgeeh is also charged with attempting to murder US soldiers.
He faces 15 years in prison for each of the three material support charges, and 20 years each for the murder charges.
