The sentencing phase for Maj. Nidal Hasan is set to start this morning.
Hasan was found guilty Friday of all charges stemming from the 2009 Fort Hood shootings.
That includes 13 counts of premeditated murder and 32 counts of attempted premeditated murder.
Hasan could be put to death for his crimes. He represented himself and offered little in the way of a defense throughout the trial. Military Judge Col. Tara Osborn warned Hasan it was not a good idea for him to represent himself during sentencing.
But Hasan said he still plans to continue as his own attorney.Legal experts say Hasan will likely be allowed to present his Defense of Others argument, which was banned at trial.
He claims that the war in Afghanistan was illegal and that he shot his fellow soldiers to protect the Taliban.
Five active duty military members are on death row, but no military member has been executed in more than 50 years.
The prosecution is expected to call family members of those killed in the attack during Monday's sentencing hearing.
