The trial of Army Maj. Nidal Hasan, the man accused in the 2009 Fort Hood massacre, is getting underway Tuesday.
Hasan is acting as his own lawyer, meaning victims of the 2009 terrorist rampage at the Texas military base will face questioning from the very man who shot them.
The military is still classifying the attack as "workplace violence."
Army Secretary John McHugh said calling it terrorism would limit their ability to bring the case to trial. But survivors say it keeps them from receiving the same medical benefits as combat victims.
The shooter killed 13 people and wounded more than 30 in the terrorist attack in 2009.
"He jumped up, pulled his weapon, yelled Allahu Akhbar and started firing on innocent, defenseless service members," Ret. U.S. Army Staff Sgt. Alonzo Lunsford, one of the survivors, recalled.
Hasan recently renounced his U.S. citizenship, saying democracy and Islamic Sharia law cannot coexist.
He has also described the deceased al Qaeda terrorist Anwar al-Awlaki as his "teacher, mentor and friend."
