John McCain actually said...

"Mr. Walker and Mr. McCracken, how many American or coalition instructors were there for the number of Afghan trainees?"

"Mr. Walker and Mr. McCracken, are you familiar with any incident where an Afghan trainee threatened or attacked an American or coalition instructor?"

"Mr. McCracken, what lessons learned from your experience with Paravant have you incorporated into your oversight of other contractors you oversee in Afghanistan?"

"Mr. Walker and Mr. McCracken, did the trainees have access to weapons and live ammunition?"
