They include a U.S. Air Force veteran accused of waging war on the country he once served and a National Guard soldier who allegedly plotted to gun down his own colleagues.
Others are seemingly ordinary American citizens, including a young nurse, a pizza parlor boss and schoolgirls tricked into becoming shrouded isis brides.

Following a series of raids in April, eight Somali friends were charged with conspiracy to provide material support and attempting to provide material support to a foreign terrorist organization.
