Former army psychologist Nidal Hasan, convicted of the 2009 Ft. Hood shooting massacre, is asking to become a citizen of the Islamic State.
His appeal comes one year after a military jury sentenced Hasan to death for a rampage on the Ft. Hood base in Texas that killed 13 people and injured more than 30.
Hasan wrote a letter from prison to the declared caliph of the Islamic State, Abu Bakr al-Baghdadi.
"It would be an honor for any believers to be an obedient citizen soldier to a people and its leader who don't compromise the religion of All-Mighty Allah to get along with disbelievers," he wrote.

Hasan is incarcerated at Ft. Leavenworth, Kansas. The U.S. government declared the Ft. Hood shooting to be an act of "workplace violence" rather than terrorism, despite numerous signs that Hasan's jihadist goals were the foundation for his motivation in the killings.
Critics of that decision say it's time for the government to reclassify the attack as an act of terrorism against American soldiers.
Victims of the attack have been unable to receive compensation and medical benefits due to terror victims because of the government's classification.
