On August 15, 2007, jurors began deliberations in the trial of Jose Padilla and co-defendants Adham Amin Hassoun and Kifah Wael Jayyousi. All three defendants were accused of conspiring to murder US nationals, conspiracy to provide material support to terrorists, and providing material support to terrorists. Padilla, a US citizen, was arrested in 2002 at Chicago's O'Hare International Airport and subsequently detained as an "enemy combatant" at a Navy military brig in Charleston, North Carolina. His case raised legal controversy over the definition of enemy combatant until he was transferred to civilian custody in January 2006 as a criminal defendant. All three men were eventually convicted on all the charges against them. Padilla was sentenced to 17 years and four months in prison.
