I'm excited for the challenge of the Arizona Ironman and putting my body through such a test.

The possibility of friendly fire, I say the possibility, did not come from the air. It was not about bombs. So we are now investigating where this possible friendly fire came from, but it was not from an aircraft of any type.

Our thoughts and prayers are with the families and loved ones of these soldiers.

The cooperation between Afghan authorities and the coalition across southern Afghanistan will not be disrupted or broken by these acts of senseless violence.

We are investigating the incident and we will work jointly with the government of Afghanistan to determine the events that took place during this fight.
