Gregory Hubbard, 54, an ex-Marine, was arrested at Miami International Airport in July 2016 attempting to travel to Syria and fight on behalf of the Islamic State. He will receive 12 years in prison, the Justice Department announced.
Two co-defendants who plotted to provide guns and other help to the Islamic State received lesser sentences. Dayne Christian, 33, and Darren Arness Jackson, 52, were sentenced to eight and four years, respectively. Jackson drove Hubbard to the airport, prosecutors said.
