A military judge has granted U.S. Army Major Nidal Hasan permission to represent himself in his trial for the deadly 2009 terror attack at Fort Hood, Texas.
The U.S.-born Muslim is charged with 13 counts of premeditated murder and 32 counts of attempted murder.
Hasan will argue he shot Americans to protect Muslims oversees when he opened fire at the base. It's called the "defense of others" strategy.
The Army major opposed the Iraq and Afghanistan wars and was weeks away from being deployed before the mass shooting.
Victims are outraged the former Army psychiatrist will now be allowed to question the same wounded soldiers he's accused of shooting. They're concerned he will try to intimidate witnesses.
Jury selection is slated to begin Wednesday.
Hasan, who was shot in the attack, is paralyzed from the chest down. If convicted, he could face the death penalty.
