I missed Graham but it doesn't suprise me. I don't trust him.
Leahey, et al, did a good job trying to force Gonzales to discuss operational details
...because actually Leahey did an atrocious, transparent, and juvenile job of trying to get Gonzales to discuss classified operational intelligence information in a public forum.
I can't recall the exact questions - some were along the lines of "How many times have you wiretapped communications in the program?" - but when Gonzales slapped him down, Leahey would come right back with "Well let me ask it this way", and then using some cheap semantic trick to ask precisely the same question, which Gonzales would spank him for again.
It really left Leahey looking like the complete dolt that he is.
